The distillery sector is one of the seventeen categories of major polluting industries in India. These units generate large volume of dark brown colored wastewater, which is known as "spent wash". Liquid wastes from breweries and distilleries possess a characteristically high pollution load and have continued to pose a critical problem of environmental pollution in many countries. The principal pollution effects of the wastewaters of these fermentation industries on a water course are multiple

... n natures. An attempt has been made to high light the treatment of distillery spent wash by using natural adsorbent. The results obtained herein indicate the feasibility of activated carbon used as an adsorbent for removal of pollutants from distillery spent wash. The results show the significant amount of reduction of pollutants by activated carbon. The study concluded that adsorbent dosage, contact time and effluent dilutions all the three are important parameters affecting the pollutants removal by adsorption.
