Electroplating industry wastewater treatment: advanced solutions

Summary

An innovative technology of electroplating industry wastewater treatment on the basis of electroflotation and ultrafiltration combination has been developed. From technical and economic point of view this technology provides for removing heavy metals from wastewater to 0.01 mg/l, SS and oil products to 0.05 mg/l at relatively low wastewater treatment facilities operational expenditures. The electroflotation plant and unltrafiltration unit on the basis of tubular ceramic membranes are recommended for introduction at the industrial wastewater treatment facilities that are either subject to upgrade or under construction. The main task of the technology and equipment designers is the reduction of the treatment facilities construction and operation expenses while maintaining the high quality of treatment.

Key words

wastewater treatment , ultrafiltration , heavy metals , ceramic membrane , electroflotation
