Abstract:
-The meat processing sector is proliferating with the increasing demand for meat. Facilities use a large volume of water for animal slaughtering, meat processing and cleaning. In the last three decades, meat production has doubled, which projected a sharp increase in meat production by 2050. Abattoir wastewater has a complex composition that includes nutrients, fibres, proteins, and fats from animal slaughtering. These nutrients cause eutrophication in water bodies when discharged without treatment. Therefore, it is very important to treat Abbotair's wastewater due to high BOD, COD, TDS, TSS, Nitrate and Phosphate concentrations. The study aims to treat Abbotair's wastewater by using an integrated approach and meet the National Environmental Quality Standards (NEQS) discharge standards and use it as irrigation water. The use of sludge produced as Blood Meal in vegetable growth which acts as slow-release fertilizer in the soil is also an objective of this study. In the study, Integrated approaches like preliminary, settling, aeration, chemical precipitation, coagulation, flocculation and Biochar were used for treatment. Biochar is also considered a medium for removing nutrients from wastewater due to its excellent binding structural properties. By using these approaches BOD and COD were removed from the wastewater by 98 percent. Nutrients were removed by 99 percent from Abbotair's wastewater. The TSS value of wastewater was reduced by 97 percent. Due to the treatment methods, wastewater becomes colorless and odorless which indicates the reduction of pollution load. Use of different treatment techniques, high organic loaded wastewater become reusable and meet the NEQS standards.
