![]() ![]() Is often inadvertently contaminated with many toxic organic and Suitable for discharge or reuse back into the environment. Its objective is to produce a waste stream and a solid waste Sewage treatment is the process of removingĬontaminants from waste-water by physical, chemical, and biological Treated waste-water for gardening purpose and reduce the pressure on Treatment is to convert this solid portion to a manageable sludge (2 %ĭry) while leaving effluent (0.003 % dry solids) and to use this Grit is composed of proteins,Ĭarbohydrates and fats, salts etc. Greases, oils, soaps, salts, metals, detergents, solvents, dyes, and This solid material consists of a mixture of faces, food particles, ![]() Material that requires being removed amount to just 0.1 % by volume. The strength and composition of waste-waterĬhanges on an hourly, daily and seasonal basis, with average strengthĭependent on per capita water usage, infiltration, surface run off as Own waste-water prior to its disposal to the local sewer to reduce the ![]() It is generally cheaper for waste-water producer to treat its Waste-waters and finally, municipal waste- water which is a mixture of In its broadest sense waste-water canīe split into domestic waste-water also known as sewage, industrial It is a complex mixture that ends up at the waste-water Mixed with man made substances, including material washed from roads, Waste-water is a complex mixture of natural inorganic materials As global economy expands rapidlyĭevelopment of new industries exerts more and more pressure onĮnvironment in relation to the disposal of waste- water after proper Pollution of water by organic and inorganic chemicals is of seriousĮnvironmental concern. Quality was suitable for gardening purposes. The results of COD after treatment were reduced from Using aeration and settling technique in the same treatment reactor at Treatment of waste-water wasĬarried out by conventional sequencing batch reactor technique (SBR) Waste-water parameters were above the National Environmental Quality (treated waste-water) were characterized using the standard methods ofĮxamination for water and waste- water. In this study all the parametersĬOD, BOD and TSS etc of influent (untreated waste-water) and effluent Treatment of sewage mixed with waste -water of research and testing Summary: These studies were conducted on the characterization and Retrieved from īyline: NAZ IMTIAZ, MUHAMMAD TAHIR BUTT, RAUF AHMAD KHAN MUHAMMAD APA style: Treatment of Laboratory Wastewater by Sequence Batch Reactor Technology.Treatment of Laboratory Wastewater by Sequence Batch Reactor Technology."

The authors also would like to thank the Brazilian National Council for Scientific and Technological Development (CNPq). The authors acknowledge the unified scholarship program for undergraduate students from the University of São Paulo and Laboratory of Chemical Waste of the University of São Paulo – Campus of Ribeirão Preto, SP, Brazil and the Central Administration of the USP Campus of Ribeirão Preto. The proposition of a comprehensive classification for chemical wastes generated in CWTLs is also highlighted. The novelty of this work is in the fact of using production and operations management tools in the management of CWTLs to propose diagnoses to improve the management of their processes. ![]()
