        abstract = {Heavy metal pollution has become one of the most serious environmental problems today. There are several acidic waste water from chemical process industries which consist of heavy metals. The treatment
of heavy metals is of special concern due to their recalcitrance and persistence in the environment. One of the waste water from process industries has been selected to seprate selectively iron and chromium from acidic wastewater. In recent years, various methods for heavy metal removal from wastewater have been extensively studied.The concentration of both metals are in range of 500-600 ppm first precipitation of iron and chromium will be evaluated to reduce the concentration. After maximum removal reactive extraction will be applied to separate metals. Design of experiments will be applied for metals selectively. This waste water treatment has not found in literature as per our findings. It is applied first time as per methodology explained. This paper reviews the current methods that have been used to treat heavy metal wastewater and evaluates these techniques. These technologies include chemical precipitation, ion-exchange, adsorption, membrane filtration, coagulationeflocculation, flotation and electrochemical methods. It is evident from the literaturesurvey articles that ion-exchange, adsorption and membrane filtration are the most frequently studied for the treatment of heavy metal wastewater.
