Methods for treating industrial wastewater containing heavy metals often involve technologies for reduction of toxicity in order to meet technology-based treatment standards. This article was focused on the recently developed and newly applicable various treatment processes for the removal of heavy metals from industrial wastewater. Metal removal from wastewater using peat, fish scales, sea-shells, membrane filtration pf PGA- based nano particles, novel biofiltation methods, activated charcoal were discussed. Their advantages and drawbacks in application were evaluated.
