摘要：In general iron industries are present in large number when compared to other industries in Tamil Nadu. Efforts are taken to prevent the iron industry effluent pollution in India, but it is not successful due to so many factors. Hence an attempt has been taken to solve the impact of Iron industry pollution by using non conventional energy sources like solar energy. Black body Kadappa stone tank are utilized for evaporation of the iron industry effluent to zero level discharge of the effluent. Hence it is very useful for the successful effort to ensure zero level discharge. The utilization of overall depth of the primary black kadappa tank is around 9cm to 10cm just like evaporation of sea water on land for the preparation of the salt. By using solar evaporation, the chemicals and salts can be evaporated and recycled.
