About this document
Spent Wash Treatment Methods in Distilleries by tej pal singh katiyar is a document available to read on EtoBox.
This document discusses treatment of distillery spent wash, a highly polluting waste generated from molasses-based alcohol distilleries. It has a high biochemical oxygen demand (BOD) of 30,000-60,000 mg/L. The best treatment option is anaerobic digestion to reduce BOD, but it only lowers it to 2,000-4,000 mg/L. Additional aerobic treatment like activated sludge process is needed to further reduce BOD below discharge limits of 20-30 mg/L. However, color still persists and requires further tertiary treatment
