This is qualitative research, and by random sampling, it is focused on to the dry zone of Sri Lanka. The research limitation has been set to the use of Ingini seeds (Strychnos potatorum) to purify water. Here the research is based on connecting traditional knowledge regarding water purification using Ingini seeds to modern times and the advantages and disadvantages of using Ingini seeds to purify water sources. Ingini seeds have been used among villagers of the dry zone to purify water for a long time by methods such as planting Ingini plants around water sources and depositing seeds covered with a cotton cloth inside wells. Crushed Ingini seeds have been put into clay water pots to reduce the hardness of water, as well as the number of impurities present in the water. This shows that Ingini seeds have a property that is successful in precipitating dissolved impurities in water. Ingini seeds are also used to precipitate solid impurities in herbal wine. The advantages of using Ingini seeds are that it can be obtained naturally from the ecology without an additional cost and that it is completely organic forest produce. Another specialty is that in practices, it is used to treat kidney stones and other water-related diseases affecting the kidneys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=folklife" title="folklife">folklife</a>, <a href="https://publications.waset.org/abstracts/search?q=Ingini%20seeds" title=" Ingini seeds"> Ingini seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=Strychnos%20potatorum" title=" Strychnos potatorum"> Strychnos potatorum</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20forest%20produce" title=" organic forest produce"> organic forest produce</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20purification" title=" water purification"> water purification</a> </p> <a href="https://publications.waset.org/abstracts/128366/ingini-seeds-a-qualitative-study-on-its-use-in-water-purification-in-the-dry-zone-of-sri-lanka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128366.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31600</span> The Research of Water Levels in the Zhinvali Water Reservoir and Results of Field Research on the Debris Flow Tributaries of the River Tetri Aragvi Flowing in It</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Givi%20Gavardashvili">Givi Gavardashvili</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduard%20Kukhalashvili"> Eduard Kukhalashvili</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamriko%20Supatashvili"> Tamriko Supatashvili</a>, <a href="https://publications.waset.org/abstracts/search?q=Giorgi%20Natroshvili"> Giorgi Natroshvili</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantine%20Bziava"> Konstantine Bziava</a>, <a href="https://publications.waset.org/abstracts/search?q=Irma%20Qufarashvili"> Irma Qufarashvili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the article to research water levels in the Zhinvali water reservoirs by field and theoretical research and using GPS and GIS technologies has been established dynamic of water reservoirs changes in the suitable coordinates and has been made water reservoir maps and is lined in the 3D format.

In order to deliver water from resources to the users, many procedures should be taken by the water engineers. One of the main procedures to deliver water to the community is by designing pressurizer pipe networks for water. The main aim of this work is to calculate the water demand of a small town and then design a simple water network to distribute water resources among the town with the smallest losses. Literature has been mentioned to cover the main point related to water distribution. Moreover, the methodology has introduced two approaches to solve the research problem, one by the iterative method of Hardy-cross and the other by water software Pipe Flow. The results have introduced two main designs to satisfy the same research requirements. Finally, the researchers have concluded that the use of water software provides more abilities and options for water engineers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=looping%20pipe%20networks" title="looping pipe networks">looping pipe networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hardy%20cross%20networks%20accuracy" title=" hardy cross networks accuracy"> hardy cross networks accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20error%20of%20hardy%20cross%20method" title=" relative error of hardy cross method"> relative error of hardy cross method</a> </p> <a href="https://publications.waset.org/abstracts/156922/comparison-between-hardy-cross-method-and-water-software-to-solve-a-pipe-networking-design-problem-for-a-small-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156922.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31596</span> The Relation of Water Intake with Level of Knowledge Related to Water Intake in Workers of Food Production Unit, Nutrition Installation at Puspa Hospital, Jakarta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Rahmah%20Fitrianti">Siti Rahmah Fitrianti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mela%20Milani"> Mela Milani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inadequate of water intake has negative effects on the health of the body, which can cause kidney failure and death. One of the factors that can affect someone intake of water is level of knowledge about the importance of water intake itself. A good knowledge of the daily water intake can increase the awareness of daily needed of water intake. Therefore, researchers initiated a study on the relationship of water intake to the level of knowledge related with water intake in food workers, at “Puspa” Hospital. Type of this research is quantitative research with cross-sectional approach. The research data was collected by measuring the independent and dependent variable at a time. This study took place in the food production unit of Nutrition Installation in "Puspa" Hospital, Jakarta in October 2016. The population target in this study were workers in food production unit aged 30-64 years. The instrument was a questionnaire question regarding water intake and 24 hours food recall. The result is 78.6% of respondents have less knowledge about the importance of water intake. Meanwhile, as many as 85.7% of respondents have adequate water intake. Tested by Chi-Square test, showed that no significant relationship between water intake with the level of knowledge related to water intake in workers of food production unit. Adequate intake of water in food workers commonly may be not caused by the level of knowledge related to water intake, but it may be cause of work environment factor which has a high temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20production%20unit" title="food production unit">food production unit</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20workers" title=" food workers"> food workers</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20knowledge" title=" level of knowledge"> level of knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20intake" title=" water intake"> water intake</a> </p> <a href="https://publications.waset.org/abstracts/63242/the-relation-of-water-intake-with-level-of-knowledge-related-to-water-intake-in-workers-of-food-production-unit-nutrition-installation-at-puspa-hospital-jakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63242.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31595</span> Demulsification of Oil from Produced water Using Fibrous Coalescer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nutcha%20Thianbut">Nutcha Thianbut</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the petroleum drilling industry, besides oil and gas, water is also produced from petroleum production. which will have oil droplets dispersed in the water as an emulsion. Commonly referred to as produced water, most industrial water-based produced water methods use the method of pumping water back into wells or catchment areas. because it cannot be utilized further, but in the compression of water each time, the cost is quite high. And the survey found that the amount of water from the petroleum production process has increased every year. In this research, we would like to study the removal of oil in produced water by the Coalescer device using fibers from agricultural waste as an intermediary. As an alternative to reduce the cost of water management in the petroleum drilling industry. The objectives of this research are 1. To study the fiber pretreatment by chemical process for the efficiency of oil-water separation 2. To study and design the fiber-packed coalescer device to destroy the emulsion of crude oil in water. 3. To study the working conditions of coalescer devices in emulsion destruction. using a fiber medium. In this research, the experiment was divided into two parts. The first part will study the absorbency of fibers. It compares untreated fibers with chemically treated alkaline fibers that change over time as well as adjusting the amount of fiber on the absorbency of the fiber and the second part will study the separation of oil from produced water by Coalescer equipment using fiber as medium to study the optimum condition of coalescer equipment for further development and industrial application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=produced%20water" title="produced water">produced water</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber" title=" fiber"> fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20modification" title=" surface modification"> surface modification</a>, <a href="https://publications.waset.org/abstracts/search?q=coalescer" title=" coalescer"> coalescer</a> </p> <a href="https://publications.waset.org/abstracts/144197/demulsification-of-oil-from-produced-water-using-fibrous-coalescer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144197.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31594</span> Minimizing Fresh and Wastewater Using Water Pinch Technique in Petrochemical Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wasif%20Mughees">Wasif Mughees</a>, <a href="https://publications.waset.org/abstracts/search?q=Malik%20Al-Ahmad"> Malik Al-Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem"> Muhammad Naeem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research involves the design and analysis of pinch-based water/wastewater networks to minimize water utility in the petrochemical and petroleum industries.

It meets the majority of its water requirement through desalination process which is very expensive. Pressures are expected to mount on account of high population growth rate and demands posed by being the venue for 2022 FIFA World cup. This study contributes towards advancing the knowledge of the factors affecting sustainable water consumption in water-challenged societies by examining the case of Doha, Qatar. Survey research methods have been predominantly used for this research. Surveys were conducted using self-administered questionnaires. Focused group interviews and personal interviews with Qatar’s residents were also used to obtain deeper insights. Salient socio-cultural factors that drive the water consumption behavior of the public and which in turn affect sustainable water management practices are determined. Suggestions for reducing water consumption as well as fiscal and punitive measures to curb overuse and misuse of water are also identified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Middle%20East" title="Middle East">Middle East</a>, <a href="https://publications.waset.org/abstracts/search?q=Qatar" title=" Qatar"> Qatar</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20consumption" title=" water consumption"> water consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20management" title=" water management"> water management</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/88496/factors-affecting-sustainable-water-management-in-water-challenged-societies-case-study-of-doha-qatar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88496.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31591</span> An Experimental Investigation of Air Entrainment Due to Water Jets in Crossflows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mina%20Esmi%20Jahromi">Mina Esmi Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Khiadani"> Mehdi Khiadani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vertical water jets discharging into free surface turbulent cross flows result in the ingression of a large amount of air in the body of water and form a region of two-phase air-water flow with a considerable interfacial area.

It is customary that we use a water tank to create shallow water flow. While a flow in a water tank is not necessarily uniform and is sometimes wavy, we can visualize a clear supercritical flow even when we move a body manually in stationary water in a simple shallow tin box. We can visualize a blunt shock wave around a moving circular cylinder together with a shock pattern around a diamond airfoil. Another interesting analogous experiment is a hydrodynamic shock tube with water and tea. We observe the contact surface clearly due to color difference of the two liquids those are invisible in the real gas dynamics experiment. We first revisit the similarities between high-speed aerodynamics and shallow water hydraulics. Several educational and research experiments are then introduced for engineering students. Shallow water experiments in a tin box simulate properly the high-speed flows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics%20compressible%20flow" title="aerodynamics compressible flow">aerodynamics compressible flow</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20dynamics" title=" gas dynamics"> gas dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulics" title=" hydraulics"> hydraulics</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20wave" title=" shock wave"> shock wave</a> </p> <a href="https://publications.waset.org/abstracts/68545/desktop-high-speed-aerodynamics-by-shallow-water-analogy-in-a-tin-box-for-engineering-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68545.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31587</span> Revolution Biopolibag System Based on Water Hyacinth's Fiber as a Solution for Environmental Friendly Seeding and Seedling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Supriady%20R.%20P.%20Siregar">Supriady R.

The common type that used for polybag is a synthetic that made from petroleum such as polyethylene. Beside the character of the raw material that are non-renewable and limited, synthetic polybag ability to disintegrate in the environment is very low. According to that situation, we need a solution to overcome these problems by creating an environmentally friendly polybag. In this research, using the water hyacinth plant fibers (Eichornia crassipes) as a major component in manufacturing the environmentally friendly polybag, the water hyacinth (Eichornia crassipes) contains approximately 60% cellulose. The research method used is an experiment by testing the mechanical characters and biodegradability bio-polybag water hyacinth fibers (Eichornia crassipes) on three medium that is dissolved in water, river water and buried in soil. The research shows bio-polybag of hyacinth fibers can rapidly degraded. This study is expected to be the beginning of the creation bio-polybag of water hyacinth fiber (Eichornia crassipes) and can be applied in agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=revolution" title="revolution">revolution</a>, <a href="https://publications.waset.org/abstracts/search?q=biopolybag" title=" biopolybag"> biopolybag</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable" title=" renewable"> renewable</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/60186/revolution-biopolibag-system-based-on-water-hyacinths-fiber-as-a-solution-for-environmental-friendly-seeding-and-seedling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60186.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">240</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31586</span> Iraq Water Resources Planning: Perspectives and Prognoses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadhir%20Al-Ansari">Nadhir Al-Ansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20A.%20Ali"> Ammar A.

It covers an area of 433,970 square kilometres populated by about 32 million inhabitants. Iraq greatly relies in its water resources on the Tigris and Euphrates Rivers. Recently, Iraq is suffering from water shortage problems. This is due to external and internal factors. The former includes global warming and water resources policies of neighbouring countries while the latter includes mismanagement of its water resources. The supply and demand are predicted to be 43 and 66.8 Billion Cubic Meters (BCM) respectively in 2015, while in 2025 it will be 17.61 and 77 BCM respectively. In addition, future prediction suggests that Tigris and Euphrates Rivers will be completely dry in 2040. To overcome this problem, prudent water management policies are to be adopted. This includes Strategic Water Management Vision, development of irrigation techniques, reduction of water losses, use of non-conventional water resources and research and development planning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iraq" title="Iraq">Iraq</a>, <a href="https://publications.waset.org/abstracts/search?q=Tigris%20River" title=" Tigris River"> Tigris River</a>, <a href="https://publications.waset.org/abstracts/search?q=Euphrates%20River" title=" Euphrates River"> Euphrates River</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20scarcity" title=" water scarcity"> water scarcity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources%20management" title=" water resources management"> water resources management</a> </p> <a href="https://publications.waset.org/abstracts/13502/iraq-water-resources-planning-perspectives-and-prognoses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">449</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31585</span> An Artificial Intelligence Supported QUAL2K Model for the Simulation of Various Physiochemical Parameters of Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehvish%20Bilal">Mehvish Bilal</a>, <a href="https://publications.waset.org/abstracts/search?q=Navneet%20Singh"> Navneet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasir%20Mushtaq"> Jasir Mushtaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water pollution puts people's health at risk, and it can also impact the ecology. For practitioners of integrated water resources management (IWRM), water quality modelling may be useful for informing decisions about pollution control (such as discharge permitting) or demand management (such as abstraction permitting). To comprehend the current pollutant load, movement of effective load movement of contaminants generates effective relation between pollutants, mathematical simulation, source, and water quality is regarded as one of the best estimating tools. The current study involves the Qual2k model, which includes manual simulation of the various physiochemical characteristics of water. To this end, various sensors could be installed for the automatic simulation of various physiochemical characteristics of water. An artificial intelligence model has been proposed for the automatic simulation of water quality parameters. Models of water quality have become an effective tool for identifying worldwide water contamination, as well as the ultimate fate and behavior of contaminants in the water environment. Water quality model research is primarily conducted in Europe and other industrialized countries in the first world, where theoretical underpinnings and practical research are prioritized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=QUAL2K" title=" QUAL2K"> QUAL2K</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=physiochemical%20parameters" title=" physiochemical parameters"> physiochemical parameters</a> </p> <a href="https://publications.waset.org/abstracts/158566/an-artificial-intelligence-supported-qual2k-model-for-the-simulation-of-various-physiochemical-parameters-of-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158566.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31584</span> Research on Steam Injection Technology of Extended Range Engine Cylinder for Waste Heat Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiyuan%20Jia">Zhiyuan Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuxiu%20Sun"> Xiuxiu Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Chen"> Yong Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Hai"> Liu Hai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuangqing%20Li"> Shuangqing Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The engine cooling water and exhaust gas contain a large amount of available energy.

For the Gulf region, especially Saudi Arabia, with its limited potable water resources, the potential of the fresh water problem is highly considerable. In this research, the study involves the design and analysis of pinch-based water/wastewater networks. Multiple water/wastewater networks were developed using pinch analysis involving direct recycle/material recycle method. Property-integration technique was adopted to carry out direct recycle method. Particularly, a petroleum refinery was considered as a case study. In direct recycle methodology, minimum water discharge and minimum fresh water resource targets were estimated. Re-design (or retrofitting) of water allocation in the networks was undertaken. Chemical Oxygen Demand (COD) and hardness properties were taken as pollutants. This research was based on single and double contaminant approach for COD and hardness and the amount of fresh water was reduced from 340.0 m3/h to 149.0 m3/h (43.8%), 208.0 m3/h (61.18%) respectively. While regarding double contaminant approach, reduction in fresh water demand was 132.0 m3/h (38.8%). The required analysis was also carried out using mathematical programming technique. Operating software such as LINGO was used for these studies which have verified the graphical method results in a valuable and accurate way. Among the multiple water networks, the one possible water allocation network was developed based on mass exchange. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimization" title="minimization">minimization</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pinch" title=" water pinch"> water pinch</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20management" title=" water management"> water management</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution%20prevention" title=" pollution prevention"> pollution prevention</a> </p> <a href="https://publications.waset.org/abstracts/11953/pinch-technology-for-minimization-of-water-consumption-at-a-refinery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">478</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31582</span> Fairly Irrigation Water Distribution between Upstream and Downstream Water Users in Water Shortage Periods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Hashemy%20Shahdany">S.

Due to water scarcity, providing reliable amount of water is not possible for most of the irrigation districts in arid regions. In this paper, water level difference control is applied to keep the water level errors equal in adjacent reaches. Distant downstream decentralized configurations of the control method are designed and tested under a realistic scenario shows canal operation under water shortage. The simulation results show that the difference controllers share the water level error among all of the users in a fair way. Therefore, water deficit has a similar influence on downstream as well as upstream and water offtakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equitable%20water%20distribution" title="equitable water distribution">equitable water distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=precise%20agriculture" title=" precise agriculture"> precise agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20agriculture" title=" sustainable agriculture"> sustainable agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20shortage" title=" water shortage"> water shortage</a> </p> <a href="https://publications.waset.org/abstracts/39301/fairly-irrigation-water-distribution-between-upstream-and-downstream-water-users-in-water-shortage-periods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39301.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">462</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31581</span> Research Trends on Magnetic Graphene for Water Treatment: A Bibliometric Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20C.%20M.%20Santos">J.

A bibliometric analysis based on the Web of Science database was employed to analyze the global scientific outputs of magnetic graphene for water treatment until the present time (2012 to 2017), to improve the understanding of the research trends. The publication year, place of publication, institutes, funding agencies, journals, most cited articles, distribution outputs in thematic categories and applications were analyzed. Three major aspects analyzed including type of pollutant, treatment process and composite composition have further contributed to revealing the research trends. The most relevant research aspects of the main technologies using magnetic graphene for water treatment were summarized in this paper. The results showed that research on magnetic graphene for water treatment goes through a period of decline that might be related to a saturated field and a lack of bibliometric studies. Thus, the result of the present work will lead researchers to establish future directions in further studies using magnetic graphene for water treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomaterials" title=" nanomaterials"> nanomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=scientometrics" title=" scientometrics"> scientometrics</a> </p> <a href="https://publications.waset.org/abstracts/107523/research-trends-on-magnetic-graphene-for-water-treatment-a-bibliometric-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31580</span> Sources of Water Supply and Water Quality for Local Consumption: The Case Study of Eco-Tourism Village, Suan Luang Sub- District Municipality, Ampawa District, Samut Songkram Province, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paiboon%20Jeamponk">Paiboon Jeamponk</a>, <a href="https://publications.waset.org/abstracts/search?q=Tasanee%20Ponglaa"> Tasanee Ponglaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Patchapon%20Srisanguan"> Patchapon Srisanguan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research paper was based on an examination of sources of water supply and water quality for local consumption, conducted at eco-tourism villages of Suan Luang Sub- District Municipality of Amphawa District, Samut Songkram Province. The study incorporated both questionnaire and field work of water testing as the research tool and method. The sample size of 288 households was based on the population of the district, whereas the selected sample water sources were from 60 households: 30 samples were ground water and another 30 were surface water. Degree of heavy metal contamination in the water including copper, iron, manganese, zinc, cadmium and lead was investigated utilizing the Atomic Absorption- Direct Aspiration method. The findings unveiled that 96.0 percent of household water consumption was based on water supply, while the rest on canal, river and rain water. The household behaviour of consumption revealed that 47.2 percent of people routinely consumed water without boiling or filtering prior to consumption. The investigation of water supply quality found that the degree of heavy metal contamination including metal, lead, iron, copper, manganese and cadmium met the standards of the Department of Health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sources%20of%20water%20supply" title="sources of water supply">sources of water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title=" water supply"> water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=Thailand" title=" Thailand"> Thailand</a> </p> <a href="https://publications.waset.org/abstracts/3879/sources-of-water-supply-and-water-quality-for-local-consumption-the-case-study-of-eco-tourism-village-suan-luang-sub-district-municipality-ampawa-district-samut-songkram-province-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3879.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31579</span> Non-Revenue Water Management in Palestine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samah%20Jawad%20Jabari">Samah Jawad Jabari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water is the most important and valuable resource not only for human life but also for all living things on the planet. The water supply utilities should fulfill the water requirement quantitatively and qualitatively. Drinking water systems are exposed to both natural (hurricanes and flood) and manmade hazards (risks) that are common in Palestine. Non-Revenue Water (NRW) is a manmade risk which remains a major concern in Palestine, as the NRW levels are estimated to be at a high level. In this research, Hebron city water distribution network was taken as a case study to estimate and audit the NRW levels. The research also investigated the state of the existing water distribution system in the study area by investigating the water losses and obtained more information on NRW prevention and management practices. Data and information have been collected from the Palestinian Water Authority (PWA) and Hebron Municipality (HM) archive. In addition to that, a questionnaire has been designed and administered by the researcher in order to collect the necessary data for water auditing. The questionnaire also assessed the views of stakeholder in PWA and HM (staff) on the current status of the NRW in the Hebron water distribution system. The important result obtained by this research shows that NRW in Hebron city was high and in excess of 30%. The main factors that contribute to NRW were the inaccuracies in billing volumes, unauthorized consumption, and the method of estimating consumptions through faulty meters. Policy for NRW reduction is available in Palestine; however, it is clear that the number of qualified staff available to carry out the activities related to leak detection is low, and that there is a lack of appropriate technologies to reduce water losses and undertake sufficient system maintenance, which needs to be improved to enhance the performance of the network and decrease the level of NRW losses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-revenue%20water" title="non-revenue water">non-revenue water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20auditing" title=" water auditing"> water auditing</a>, <a href="https://publications.waset.org/abstracts/search?q=leak%20detection" title=" leak detection"> leak detection</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20meters" title=" water meters"> water meters</a> </p> <a href="https://publications.waset.org/abstracts/45389/non-revenue-water-management-in-palestine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45389.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31578</span> Rejuvenating the Water Edge: An Urban Design Initiative for Waterways.

However, these water bodies are major source of water for drinking, irrigation, industrial activities and fishery. Therefore, water quality assessment is paramount importance to evaluate its suitability for all these purposes. This study focus to evaluate the surface water quality of an industrial city in eastern India through integrating interdisciplinary techniques. The multi-purpose Water Quality Index (WQI) assess the suitability for drinking, irrigation as well as fishery of forty-eight sampling locations, where 8.33% have excellent water quality (WQI:0-25) for fishery and 10.42%, 20.83% and 45.83% have good quality (WQI:25-50), which represents its suitability for drinking irrigation and fishery respectively. However, the industrial water quality was assessed through Ryznar Stability Index (LSI), which affirmed that only 6.25% of sampling locations have neither corrosive nor scale forming properties (RSI: 6.2-6.8). Integration of these statistical analysis with geographical information system (GIS) helps in spatial assessment. It identifies of the regions where the water quality is suitable for its use in drinking, irrigation, fishery as well as industrial activities. This research demonstrates the effectiveness of statistical and GIS techniques for water quality assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20water" title="surface water">surface water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20assessment" title=" water quality assessment"> water quality assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20index" title=" water quality index"> water quality index</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20assessment" title=" spatial assessment"> spatial assessment</a> </p> <a href="https://publications.waset.org/abstracts/103597/an-investigation-of-surface-water-quality-in-an-industrial-area-using-integrated-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31575</span> The Risk Assessments of Water Quality in Selected White Water River in Malaysia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaffry%20Zakaria">Jaffry Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Azlina%20Hasbullah"> Nor Azlina Hasbullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research on water quality based on 'Water Quality Index' (WQI) has been on the run along Kampar River in Perak State of Malaysia.

Air conditioning (AC) condensate water could be explored as an alternative water source, which could be considered within the global calculations of the water supply. The objective of this study is to better understand the potential for recovery of condensate water from air conditioning systems. The results generated so far showed that the AC produces a high quantity of water, and data analysis revealed that the amount of water is positively and significantly correlated with the humidity (P <= 0.05). In the meantime, the amount of heavy metals has been measuring using ICP-OES. The results, in terms of quantity, clearly show that the AC can be used as an alternative source of water, especially in the regions characterized by high humidity. The results also showed that the amount of produced water depends on the type of AC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning%20systems" title="air conditioning systems">air conditioning systems</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quantity" title=" water quantity"> water quantity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%0D%0Aresources" title=" water resources"> water resources</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/114549/biochemical-evaluation-of-air-conditioning-west-water-in-jeddah-city-concept-of-sustainable-water-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">213</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31572</span> Importance of Determining the Water Needs of Crops in the Management of Water Resources in the Province of Djelfa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imessaoudene%20Y.">Imessaoudene Y.</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouhouche%20B."> Mouhouche B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Sengouga%20A."> Sengouga A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Kadir%20M."> Kadir M.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is to determine the virtual water of main crops grown in the province of Djelfa and water use efficiency (W.U.E.), Which is essential to approach the application and better integration with the offer in the region. In the case of agricultural production, virtual water is the volume of water evapo-transpired by crops. It depends on particular on the expertise of its producers and its global production area, warm and dry climates induce higher consumption. At the scale of the province, the determination of the quantities of virtual water is done by calculating the unit water requirements related to water irrigated hectare and total rainfall over the crop using the Cropwat 8.0 F.A.O. software. Quantifying the volume of agricultural virtual water of crops practiced in the study area demonstrates the quantitative importance of these volumes of water in terms of available water resources in the province, so the advantages which can be the concept of virtual water as an analysis tool and decision support for the management and distribution of water in scarcity situation. <p
