Biological sulfate reduction for batch and continuous removal of heavy metals from wastewater

Abstract

Heavy metals are extensively used for several applications and as a consequence of which these metals are discharged into the environment from different sources Owing to their non biodegradable and non persistent nature metals can merely be transformed to less toxic and insoluble forms Besides heavy metals sulfate is found abundant in wastewater streams which pose many environmental issues Therefore elimination of metals and sulfate from wastewater prior their discharge into the environme
