Minimum fresh water usage and emphasis on waste-water recycling/management are key factors for the growth of this industry. Concentration of impurities and toxic substances in processed water mainly limits recycling benefits because it adversely affects processes, equipments and paper quality. Organic wastes are mostly processed through biodegradation and bioremediation using anaerobic digestion (methane production) followed by aerobic digestion (inducing sludge processing). Although, biological processing is economical and eco-friendly but treatment of wastes including non-biodegradable recalcitrant compounds mostly limits its broad application. Therefore, many other innovative approaches have been exploited to tackle this problem. Advanced oxidation process (AOP), novel biodegradable polymeric flocculants, electrocoagulation and photocatalysis etc. are used as alternative ways to facilitate detoxification and recycling. In this chapter, we emphasised and provided an in-depth knowledge about the various wastewater treatment strategies linked to paper and pulp industry.</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":"Treatment and Recycling of Wastewater from Pulp and Paper Mill A","attachmentId":64841487,"attachmentType":"pdf","work_url":"https://www.academia.edu/44425432/Treatment_and_Recycling_of_Wastewater_from_Pulp_and_Paper_Mill_A","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/44425432/Treatment_and_Recycling_of_Wastewater_from_Pulp_and_Paper_Mill_A"><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="69299735" 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/69299735/Treatment_of_Wastewater_from_Pulp_and_Paper_Mill_using_Coagulation_and_Flocculation">Treatment of Wastewater from Pulp and Paper Mill using Coagulation and Flocculation</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="41831124" href="https://independent.academia.edu/BalpreetKaur15">Balpreet Kaur</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Environmental Treatment Techniques</p><p class="ds-related-work--abstract ds2-5-body-sm">In this work, an effluent sample from a local medium-scale paper mill has been treated using alum as a coagulant and chitosan (natural polymer) as a flocculant. Initially, the dose of alum has been optimized by adjusting the zeta potential to near zero for best coagulation results. The dose of 0.04 g/L was able to merely coagulate and unable to cause sweep flocculation of impurities. Then, at the optimised dose of 0.04 g/L various concentrations of chitosan in the range of 0.1-0.5 g/L were investigated for obtaining maximum flocculation of the suspended impurities. The physico-chemical parameters like pH, total suspended solids (TSS), chemical oxygen demand (COD), absorbance, and zeta potential were studied for comprehending the flocculation behavior. The observed results exhibited that the maximum flocculation was achieved at the chitosan concentration of 0.3 g/L. At the flocculant concentration of 0.3 g/L, 81% TSS removal and maximum 78% COD were reduced.

The bleaching sequence was simulated in the laboratory using four types of washing water: deionized water, whitewater, low organic load effluent, and high organic load effluent. To achieve 90% ISO pulp brightness, the ClO2 consumption increased from 8.1 kg ClO2 odt-1 when using water to 13.8 and 16.3 kgClO2 odt-1 for the low and high organic effluents. Physical and optical tests of the hand-sheet papers did not show any statistical difference between various washing waters.

This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.</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":"Wastewater Treatment and Reclamation: A Review of Pulp and Paper Industry Practices and Opportunities","attachmentId":68651923,"attachmentType":"pdf","work_url":"https://www.academia.edu/50784546/Wastewater_Treatment_and_Reclamation_A_Review_of_Pulp_and_Paper_Industry_Practices_and_Opportunities","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/50784546/Wastewater_Treatment_and_Reclamation_A_Review_of_Pulp_and_Paper_Industry_Practices_and_Opportunities"><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="4" data-entity-id="113113717" 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/113113717/Analysis_of_Pulp_and_Paper_Industrial_Effluent_and_Its_Treatment_a_Review">Analysis of Pulp and Paper Industrial Effluent and Its Treatment a Review</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="243423507" href="https://independent.academia.edu/AmbikaThakur23">Ambika Thakur</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2018</p><p class="ds-related-work--abstract ds2-5-body-sm">The pulp and paper industry is one of the water intensive industries around the world which produce a large quantity of wastewater.

One of the paper industry's prior solutions is using an acid called "p-Toluenesulfonic" to remove the lignin from water that is used in washing the pulp. This acid is soluble in water and gives a white solid material, alcohol, and other polar organic, so these materials make the water unsuitable for reuse again in the same process. In this work is presented an acid whose use does not pollute the water is called, Hydrochloric Acid (HCl). Using Hydrochloric Acid (HCl) achieved the design requirements; which are high efficiency, the water quality, which is pH, the pH of the water was equal to 3.59 and water's TDS, which was equal to 990 ppm. The prototype has been tested by washing 12g of pulp, which filled with Sodium Hydroxide (NaOH) from the previous process (cooking or firing step), with a solution of 40ml; this solution is about 39 ml of water and 1ml of Hydrochloric Acid (HCl), then the lignin precipitated and separated from the pulp and by filtering the water, it became without any lignin so that it is usable again. To conclude, using Hydrochloric Acid (HCl) is an effective way to precipitate lignin in water and make the pulp brighter.</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":"Modify process of Pulp Production in Paper Industry to Reuse Water","attachmentId":67776272,"attachmentType":"pdf","work_url":"https://www.academia.edu/49421336/Modify_process_of_Pulp_Production_in_Paper_Industry_to_Reuse_Water","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/49421336/Modify_process_of_Pulp_Production_in_Paper_Industry_to_Reuse_Water"><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="83283807" 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/83283807/Sustainable_Alternatives_for_Tertiary_Treatment_of_Pulp_and_Paper_Wastewater">Sustainable Alternatives for Tertiary Treatment of Pulp and Paper Wastewater</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="73266822" href="https://independent.academia.edu/AriannaCatenacci">Arianna Catenacci</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Sustainability</p><p class="ds-related-work--abstract ds2-5-body-sm">In this work, different alternatives to conventional tertiary treatment of pulp and paper (P&P) wastewater (WW), i.e., physicochemical coagulation-flocculation, were investigated to enhance the environmental and economic sustainability of industrial wastewater treatment. In particular, following a preliminary characterization of secondary effluents, cloth filtration and adsorption were studied, the former by pilot-scale tests, while the latter at laboratory scale. An economic analysis was finally accomplished to verify the full-scale applicability of the most promising technologies. Cloth filtration showed excellent total suspended solids (TSS) removal efficiency (mean 81% removal) but a very limited influence on chemical oxygen demand (COD) (mean 10% removal) due to the prevalence of soluble COD on particulate COD. Adsorption, instead, led to a good COD removal efficiency (50% abatement at powdered activated carbon—PAC—dosage of 400 mg/L). The economic analysis proved that adsorpti...</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":"Sustainable Alternatives for Tertiary Treatment of Pulp and Paper Wastewater","attachmentId":88681181,"attachmentType":"pdf","work_url":"https://www.academia.edu/83283807/Sustainable_Alternatives_for_Tertiary_Treatment_of_Pulp_and_Paper_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/83283807/Sustainable_Alternatives_for_Tertiary_Treatment_of_Pulp_and_Paper_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></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":89946662,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":89946662,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_89946662" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
