摘要
This invention relates to a process for the decolourisation of molasses based distillery effluent after secondary treatment. The process is environment friendly for color removal from the sugarcane based alcohol distillery effluent after biomethanation and activated sludge process. The ozone treatment processes are generally combined with UV, H2O2 microbial, fixed bed biofilm reactors, and coagulation treatments, to enhance the performance of decolorization. The wastewater is from industries like, Pulp and Paper, dye industry, municipal drainage, secondary effluent from a paper mill treatment plant. Spent wash is an unique effluent primarily composed of varied amount of caramel, melanoidins and lignins of uncertain characteristics. The carmels and melanoidins, which are of uncertain characteristics, pose difficulties for removal or treatment efficiently using the present treatment methods. In the present invention this effluent has been treated with ozone.
