A STUDY ON METALS RECOVERY FROM THE WASTE WATER EFFLUENTS IN ELECTROPLATING INDUSTRY

Rapid industrializations and urbanizations were produces very huge amounts of waste water and effluents during various unit operations and the processes. It seems to huge burden to manage to supply the sufficient quantity of water and also very difficult to manage the waste water and its effluents, and it may lead to increasing of cost and maintenance of the ETP's. In this contest this present study attempt was done for reduction of total water consumption and to recovery of Nickel and Copper metals from the waste water effluents coming from electroplating industry were analyzed by Nickel Recovery Units and Copper Recovery Units, The metals, which are casted from aluminum wheel. The recovery units, which has a rinse bath – 1, rinse bath - 2, drag out bath, copper plating bath and cartridge filter, carbon filter , copper recovery. It was found that, after following of Nickel & Copper recovery systems, total water consumption is drastically reduced, sludge generation also reduced and also effluent generation in both the cases of nickel and copper were also reduced
