摘要：Electroplating wastewater contains highly toxic cyanide, cyanide complexes and metal ions that makes treatment a complex problem. As the electroplating industries are located in tiny and unorganized sectors in India the problem becomes more grave. Due to lack of technology, Automation and process control, there is considerable change in the effluent coming from these industries. Therefore the effluent exerts variable characteristics. It is observed that effluent has high BOD/ COD, SS, DS, TS, Colour, and Turbidity and there is depletion of oxygen. Proper treatment has to be provided for the safe discharge of electroplating effluent. The paper deals with the study of different processes for the reduction of pollution load related to this industry. Basically the paper covers all the different methods that have been used for the treatment of this waste along with the recent development of treatment. The benefits and limitations of the process has been discussed. The paper will be helpful in the selection of effective treatment method based on the quantity and characteristic of the effluent generated. It will help in further optimizing the process parameters.
