The zinc present in the dead tank wash water of plating industry is of about 300 ppm approximately. The aim of the experiment was to reduce the zinc content in the effluent. Treatment by ion exchange produces reusable water. Generally dead tank wash water contains about 1% of the plating bath concentration. If this water is sent as waste the zinc present will be left unused and it pollutes the environment, so the recovery of zinc from dead tank wash water is more important.For this process the synthetic ion exchange resin Amberlite (IR-120) was used and the resin was regenerated using acid as regenerant. Mass transfer coefficient has been derived for adsorption and desorption, adsorption mass transfer coefficient has been calculated and breakthrough curve have been drawn for experimental values. The result shows that the zinc - recovery process is feasible and effective in ion exchange process. |
