Application of Engineering Microorganism for the Effective Treatment of Paint Shop Wastewater

摘要

Nowadays, there are increasingly stringent regulations requiring more and more treatment of industrial effluents to generate product water which could be easily reused or disposed of to the environment without any harmful effect. Some pollutants such as high organic, inorganic matter, heavy metals or paint stuffs resist degradation by conventional treatment methods and persist in the environment. In the present article an attempt is made to access the feasibility of recycle/reuse of wastewaters from automobile industry through conventional and advanced treatment process. The present article describes the use of engineering microorganisms as an alternative method for treatment of such recalcitrant pollutants than conventional microo rganism. The Reactor performance was evaluated using parameters like pH, DO and COD at different loading rates. It has sho wn that though the efficiency of the reactor decreases with the increase in organic load still the effluent parameters are maintained well within the specified limits. It also emphasizes the need for current and future research to focus on developing econo mically feasible and environmentally sustainable wastewater treatment practices
