Microalgal Remediation Of Electroplating Wastewater And Biomass Production -An Ecofriendly Approach

Abstract

Electroplating industrial(EPI )effluents   are the  major source of heavy and toxic metals discharged into the waste water lines. Sustainable technology through the greener path using microalgae helps to recycle the EPI effluent. In our research the removal of heavy metals in light and dark cycles using Westiellopsis was assessed and recorded the results as follows:Cr-91%,Cu-90% ,Ni-84%,Zn-86% .Response of Westiellopsis to recover the heavy metals in EPI effluent  was recorded in the descending order:Cr > Cu > Zn>Ni. The cell growth of the Westiellopsis was increased upto  95% in raw EPI effluent(T4). Cell recovery was achieved upto 100%.Among all treatments,in  T4 maximum yield of  biomass  and protein was recorded upto 97% and 95% respectively. Thus the current research on cultivating Westiellopsis in EPI effluent was an ecofriendly approach with dual advantage of reduction in heavy metal load  and high yield of dry biomass .
