Decolorization of Anaerobically Digested Molasses Spentwash by CoagulationDOI: 10.5923/j.ajee.20120201.03 Keywords: Coagulation, Decolorization, Distillery, Spentwash Abstract: Treatment of molasses spentwash has always posed a challenge to the environmental engineers. Problem becomes more difficult in the countries like India where more harsh environmental parameters of spentwash on one hand and limitation of treatment cost on the other is crude reality. Inability to grow micro-organisms in undiluted spentwash further limits the options. In this work, various options of coagulation were tried as primary treatment to make spentwash fit for further biological treatment without dilution. Poly aluminium chloride(PAC) was found to be the best coagulant.
