Wastewater Treatment Project

Problem Statement: Treatment process of slaughterhouse wastewater is complex due to the presence of high amounts of organic matter such as proteins, blood, and fat. Untreated slaughterhouse wastewater if enter municipal sewage system would pose problems due to the significantly higher concentrations of biological oxygen demand, chemical oxygen demand, total nitrogen, and total phosphorus. A number of processes including aerobic, anaerobic, and hybrid have been extensively applied for their treatment. In order to address some of the challenges associated with the established processes such as high energy demand, electrochemical treatment process has been recently introduced.

In this project, slaughterhouse wastewaters from Aligarh area will be evaluated for their BOD, COD, total nitrogen, total phosphorus, suspended solid, and total coliform. Based on the concentrations of these contaminants, appropriate treatment process mainly electrochemical methods will be extensively evaluated for waste water treatment. Long term plan is to develop a method to convert high organic containing sludge from slaughter wastewater into biodiesel.
