Abstract

The T.E Maxson Wastewater Treatment Plant (WWTP) located in Memphis, TN is designed to treat 90 million gallons per day (mgd) of municipal and industrial wastewater daily. Bar screens, Primary Clarifiers, Biotowers, Activated sludge and secondary clarifiers are main treatment units.Biotowers are one of major sources of odorous emissions usually under anaerobic condition. In other words, removing more colloidal and suspended organics in primary clarifiers can improve biotowers performance ans decrease malodorous conditions in biotowers. Chemically enhanced primary treatment (CEPT) is using chemical treatment in primary clarifiers to promote particulate contaminant removal. The main goal of this research was to study contaminant removal efficiency of different coagulants, polymers and their blends on influent wastewater of Maxson WWTP. In this regard, the effect of alum, ferric sulfate, aluminum chlorohydrate(ACH), polydiallyldimethylammonium(polyDADMAC), polyamine and ACH-polyamine, and ACH-polyDADMAC were examined in terms of enhancing removal of TSS, COD, TKN, BOD5, soluble BOD5, total phosphorus, and pH.
