The performance of a sequencing batch reactor in treating complex chemical effluents was investigated with a suspended biomass configuration and operating under aerobic conditions. A total sequence of 24 h (15 min: filling phase; 23 h: reaction phase (aeration with recirculation); 30 min: setting; and 15 min: withdrawal) was employed and studied with various organic loading rates (1.0 kg COD/m3/day: 1.7 kg COD/m3/day and 3.5 kg COD/m3/day). The SBR performance was assessed by means of carbon removal and operational parameters such as pH, oxidation–reduction potential (ORP), sludge volume (SV), sludge volume index (SVI), suspended solids (SS) and volatile suspended solids (VSS), which were monitored during reactor operation. The SBR showed relatively more efficient performance over conventional suspended growth systems. About 8% sulphate was removed under anoxic conditions at all the studied organic loading rates. Enhanced performance with SBR over conventional ASP may be due to enforced short term unsteady state conditions coupled with periodic exposure of the microorganisms (physiological state) to defined process conditions which facilitate the required metabolic conditions for treating complex chemical effluents.","author":[{"@context":"https://schema.org","@type":"Person","name":"S Venkata

The comparison study was performed by varying two significant independent variables (aeration time and mixed liquor volatile suspended solids (MLVSS)). The experiments were conducted based on a central composite design (CCD) and analyzed using response surface methodology (RSM). The region of exploration for the process was taken as the area enclosed by aeration time (6-24 h) and MLVSS (2000-7000 mg/L) boundaries. The results showed that the granulated sludge system was more efficient than the flocculated sludge system in removing the nonbiodegradable COD (nbCOD), total nitrogen (TN), total phosphorus (TP) and other sludge studied characteristics. The performance of both systems was almost the same for COD removal in FIW with a maximum removal of about 70 %.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Comparative Study on Performance of Two Aerobic Sequencing Batch Reactors with Flocculated and Granulated Sludge Treating an Industrial Estate Wastewater: Process Analysis and Modeling","attachmentId":73609680,"attachmentType":"pdf","work_url":"https://www.academia.edu/59941178/A_Comparative_Study_on_Performance_of_Two_Aerobic_Sequencing_Batch_Reactors_with_Flocculated_and_Granulated_Sludge_Treating_an_Industrial_Estate_Wastewater_Process_Analysis_and_Modeling","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/59941178/A_Comparative_Study_on_Performance_of_Two_Aerobic_Sequencing_Batch_Reactors_with_Flocculated_and_Granulated_Sludge_Treating_an_Industrial_Estate_Wastewater_Process_Analysis_and_Modeling"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="89434010" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/89434010/Effect_of_Sludge_Retention_Time_on_Treating_High_Load_Synthetic_Wastewater_Using_Aerobic_Sequencing">Effect of Sludge Retention Time on Treating High Load Synthetic Wastewater Using Aerobic Sequencing</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="155874024" href="https://sbu-ir.academia.edu/SeyedHosseinHashemi">Seyed Hossein Hashemi</a></div><p class="ds-related-work--abstract ds2-5-body-sm">The main aim of this study was to investigate the effect of sludge retention time on performance of aerobic synthetic Batch Reactor for treating a high load milk synthetic wastewater. For this purpose, four lab-scale sequencing batch reactors were operated under aerobic conditions with the same conditions at different sludge retention times (SRTs), feeding by high load milk synthetic wastewater. Operating volume, influent flow rate and influent organic loading rate for all reactors were adjusted to 5.5 L, 3.5 L/d and 1400 gCOD/m 3 d, respectively. The average effluent COD for reactor 1 to 4 with SRT of 5, 10, 15 and 20 d were 108, 97, 91 and 84 mg/L, respectively. COD removal was 94.99, 95.43, 95.86 and 96.16 percent respectively and slightly changed with SRT. However, the overall trend of COD removal vs. SRT showed an increasing rate with the correlation factor (R 2) of 0.99. Reactor 2 with SRT of 10 d(SVI) had the maximum effluent TSS ave (34mg/L) and turbidity ave (5.89 mg/L) and the minimum sludge volume index (41mL/g). All reactors had SVI ave of lower than 75 mL/g and effluent turbidity ave less than 6 NTU which was lower than Iranian national discharge standards (<50 NTU). SRT had directly influenced the biomass concentration, as the MLSS ave of reactor 1 to 4 were found to be 1824, 2694, 3210 and 3864 mg/L respectively. Best performance (minimum effluent COD, TSS and turbidity) was occurred in reactor 4 with SRT of 20 d.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Effect of Sludge Retention Time on Treating High Load Synthetic Wastewater Using Aerobic Sequencing","attachmentId":93240774,"attachmentType":"pdf","work_url":"https://www.academia.edu/89434010/Effect_of_Sludge_Retention_Time_on_Treating_High_Load_Synthetic_Wastewater_Using_Aerobic_Sequencing","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/89434010/Effect_of_Sludge_Retention_Time_on_Treating_High_Load_Synthetic_Wastewater_Using_Aerobic_Sequencing"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="8342705" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/8342705/Treatment_of_agro_based_industrial_wastewater_in_sequencing_batch_reactor_Performance_evaluation_and_growth_kinetics_of_aerobic_biomass">Treatment of agro based industrial wastewater in sequencing batch reactor: Performance evaluation and growth kinetics of aerobic biomass</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="16710709" href="https://usm.academia.edu/JXLIM">JX LIM</a></div><p class="ds-related-work--abstract ds2-5-body-sm">A sequencing batch reactor (SBR) with a working volume of 8 L and an exchange ratio of 25% was used to enrich biomass for the treatment of the anaerobically treated low pH palm oil mill effluent (POME). The influent concentration was stepwise increased from 5000 ± 500 mg COD/L to 11,500 ± 500 mg COD/L. The performance of the reactor was monitored at different organic loading rates (OLRs). It was found that approximately 90% of the COD content of the POME wastewater was successfully removed regardless of the OLR applied to the SBR. Cycle studies of the SBR show that the oxygen uptake by the biomass while there is no COD reduction may be due to the oxidation of the storage product by the biomass. Further, the growth kinetic parameters of the biomass were determined in batch experiments using respirometer. The maximum specific growth rate (m max ) was estimated to be 1.143 day À1 while the half saturation constant (K s ) with respect to COD was determined to be 0.429 g COD/L. The decay coefficient (b D ) and biomass yield (Y) were found to be 0.131 day À1 and 0.272 mg biomass/mg COD consumed, respectively.</p><div class="ds-related-work--ctas"><button

class="ds-related-work--abstract ds2-5-body-sm">The physical and biochemical characteristics of the biomass in three lab-scale sequencing batch reactors (SBR) treating a synthetic wastewater at a 20-day target solids retention time (SRT) were investigated. The synthetic wastewater feed contained biogenic compounds and 22 organic priming compounds, chosen to represent a wide variety of chemical structures with different N, P and S functional groups. At a two-day hydraulic retention time (HRT), the oxidation-reduction potential (ORP) cycled between À100 (anoxic) and 100 mV (aerobic) in the anoxic/aerobic SBR, while it remained in a range of 126718 and 249718 mV in the aerobic sequencing batch biofilm reactor (SBBR) and the aerobic SBR reactor, respectively. A granular activated sludge with excellent settleability ðSVI ¼ 98 AE 31 L mg À1 Þ developed only in the anoxic/aerobic SBR, compared to a bulky sludge with poor settling characteristics in the aerobic SBR and SBBR. While all reactors had very good COD removal (490%) and displayed nitrification, substantial nitrogen removal (74%) was only achieved in the anoxic/aerobic SBR. During the entire operational period, benzoate, theophylline and 4-chlorophenol were completely removed in all reactors. In contrast, effluent 3-nitrobenzoate was recorded when its influent concentration was increased to 5 mg L À1 and dropped only to below 1 mg L À1 after 300 days of operation. The competent (active) biomass fractions for these compounds were between 0.04% and 5.52% of the total biomass inferred from substrate-specific microbial enumerations. The measured competent biomass fractions for 4-chlorophenol and 3-nitrobenzoate degradation were significantly lower than the influent COD fractions of these compounds. Correspondent to the highest competent biomass fraction for benzoate degradation among the test SOCs, benzoate oxidation could be quantified with an extant respirometric technique, with the highest specific oxygen uptake rate (SOUR benzoate , 0.026 g O 2 h À1 g À1 XCOD) in the anoxic/aerobic SBR. These combined results suggest that operating SBRs with alternative anoxic/aerobic cycles might facilitate the formation of granular sludge with good settleability, and retain comparable removal of nitrogen and synthetic organic compounds. Hence, the practice of anoxic/aerobic cycling should be considered in wastewater treatment systems whenever possible. r</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Biomass characteristics in three sequencing batch reactors treating a wastewater containing synthetic organic chemicals","attachmentId":45120207,"attachmentType":"pdf","work_url":"https://www.academia.edu/13638484/Biomass_characteristics_in_three_sequencing_batch_reactors_treating_a_wastewater_containing_synthetic_organic_chemicals","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/13638484/Biomass_characteristics_in_three_sequencing_batch_reactors_treating_a_wastewater_containing_synthetic_organic_chemicals"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="106126161" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/106126161/Optimization_of_Biological_Treatment_of_an_Industrial_Wastewater_in_an_Intermittent_Aeration_Sequencing_Batch_Reactor">Optimization of Biological Treatment of an Industrial Wastewater in an Intermittent Aeration Sequencing Batch Reactor</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="265641059" href="https://yasouj.academia.edu/AzarAsadi">Azar Asadi</a></div><p class="ds-related-work--abstract ds2-5-body-sm">In this paper, the simultaneous removal of carbon and nutrients (nitrogen and phosphorus) from Faraman's industrial wastewater (FIW) in a time-based sequencing batch reactor (SBR) was investigated. The experiments were conducted based on a central composite design (CCD) and analyzed using the response surface methodology (RSM). Reaction and aeration times were selected for the purposes of analyzing, modeling, and optimizing the process. Nine dependent parameters were monitored as process responses. The region of exploration for the process was taken as the area enclosed by the boundaries of reaction time (12-36 h) and aeration time (40-60 min/h). Reaction time was found to be the most effective variable and showed a decreasing impact on the total chemical oxygen demand (TCOD), slowly-biodegradable chemical oxygen demand (sbCOD), total nitrogen (TN), and total phosphorus (TP) removal efficiencies. The optimum operating conditions were determined in the range of 12 to 16 h for the reaction time and 40 to 60 min/h for the aeration time.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Optimization of Biological Treatment of an Industrial Wastewater in an Intermittent Aeration Sequencing Batch Reactor","attachmentId":105405428,"attachmentType":"pdf","work_url":"https://www.academia.edu/106126161/Optimization_of_Biological_Treatment_of_an_Industrial_Wastewater_in_an_Intermittent_Aeration_Sequencing_Batch_Reactor","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/106126161/Optimization_of_Biological_Treatment_of_an_Industrial_Wastewater_in_an_Intermittent_Aeration_Sequencing_Batch_Reactor"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="77076445" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/77076445/Utilization_of_a_hybrid_sequencing_batch_reactor_HSBR_as_a_decentralized_system_of_domestic_wastewater_treatment">Utilization of a hybrid sequencing batch reactor (HSBR) as a decentralized system of domestic wastewater treatment</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="171528209" href="https://independent.academia.edu/LamegoLuiz">Luiz Lamego</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Water Science & Technology, 2008</p><p class="ds-related-work--abstract ds2-5-body-sm">This paper presents the experiments carried out in a hybrid sequencing batch reactor (HSBR), used for biological treatment of sewage.

This consisted of a nylon net disposed in a grille for biofilm biomass adhesion. The reactor worked fully automated in operational cycles of maximum 8 hours each, presenting the following phases: filling, anoxic, aerobic, settle and draw of treated effluent, with 3 fillings per cycle. Increasing organic loads (0.14 to 0.51 kg TCOD/m3 day) and ammonium loads (0.002 to 0.006 kg NH4-N/m3·day) were tested.

During these studies different organic loading rates (0.29, 0.82 and 1.1 kg COD/m 3 d for Set I and Set II, and 0.29 and 0.62 kg COD/m 3 d for Set III), hydraulic retention times (11, 15, 25 h), temperatures (10, 15, 25°C) and at different anaerobic sludge concentrations (about 5, 10 g VSS/L) in the reactor were applied and the performance of the reactor was tested. It was observed that treatment of low strength wastewaters under low temperature was possible. Even at the lowest temperature applied and lowest sludge amount the total organic matter (COD) removal was 65.2%. However, the COD removal and methane production decreased with decreasing temperature and HRT. The COD removal efficiencies decreased when the system was fed with settled real domestic wastewater probably due to more complex structure of the domestic wastewater and the presence of suspended solids even in small concentrations. These results showed that the ASBR process can be used for treatment of low strength wastewaters at low temperatures.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Effects of Temperature and Biomass Concentration on the Performance of Anaerobic Sequencing Batch Reactor Treating Low Strength Wastewater","attachmentId":32177420,"attachmentType":"pdf","work_url":"https://www.academia.edu/4913982/Effects_of_Temperature_and_Biomass_Concentration_on_the_Performance_of_Anaerobic_Sequencing_Batch_Reactor_Treating_Low_Strength_Wastewater","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/4913982/Effects_of_Temperature_and_Biomass_Concentration_on_the_Performance_of_Anaerobic_Sequencing_Batch_Reactor_Treating_Low_Strength_Wastewater"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="85504559" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/85504559/Biological_nutrient_removal_from_industrial_wastewater_using_a_sequencing_batch_reactor">Biological nutrient removal from industrial wastewater using a sequencing batch reactor</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="61445134" href="https://independent.academia.edu/siphesihlekhumalo2">siphesihle khumalo</a></div><p class="ds-related-work--abstract ds2-5-body-sm">South Africa is not an exception when it comes to the issue of fresh water scarcity perpetuated by environmental pollution among many other factors.
