Sludge reduction by advanced Oxidation fenton and modified Fenton processes through Deflocculation using citric acid

Abstract

In recent years generation of waste activated sludge WAS newlineincreased in huge quantity from urban waste water treatment plants Now a newlinedays municipal waste water treatment is mandatory as it reduces the organic newlinematter and pathogens before it discharged to water sources Disposal of newlineexcess sludge from the waste water treatment plants WWTP had become a newlineserious environmental problem Therefore sludge treatment is necessary newlinebefore its final disposal The fundamental problem faced by industries and newlinemunicipal WWTP is treatment and disposal of sludge which occupies as most newlineexpensive part of waste water treatment Conventional activated sludge newlineprocess is normally employed in many of the WWTPs due to their easy newlineoperation high treatment efficiency and low operational newline newline
