Abstract

Exploratory experiments were performed to test the feasibility of coagulation and flocculation as a post treatment process for the effluent of an Upflow Anaerobic Sludge Blanket (UASB) reactor treating domestic sewage. Commonly used coagulants [Alum, Polyaluminium Chloride (PAC)] were utilized in a series of jar tests to determine the optimum coagulant dose. The optimum chemical dosage was 500 mg/L to 600mg/L for [Alum, Polyaluminium Chloride (PAC)] respectively.It was found that all the tested coagulants were effective in reducing the effluent BOD ,COD and SS Coagulation treatment is also efficient in reduction of nutrient from wastewater because by coagulation we can reduce Phosphorous and Nitrogen up to 85-92 % and 75-85% respectively. It was found Coagulation give better results than aeration for post treatment of UASB effluent.
