Removal of heavy metals from electroplating plant wastewater with using sulfide ions produced by sulfate-reducing bacteria
Five Cr(VI), Ni, Cu and Zn-contg. wastewaters from an electroplating plant were purified by addn. of sulfates-reducing bacteria in their Na(2)SO(4) and Na lactate-contg. cultures at pH 8.6. The bacteria were isolated from municipal sewage. The metals were removed as H(2)O-insol. sulfides or hydroxides with high efficiency (over 99%).
