The Present work deals with a study that involves examining the efficacy of introducing reverse osmosis (RO) process in distillery wastewater treatment as an alternative polishing treatment for the ultimate objective of planning zero discharge from ETP system. It specifically studies alternative systems viz., ferti-irrigation, biocomposting without RO and biocomposting with RO treatment system after anaerobic treatment for a distillery of capacity 120 KLD for comparing other alternatives in vague. The operating costs for ferti-irrigation, biocomposting without RO and biocomposting with RO...
