Abstract :-Water is one of the most important key for life. Due to rapid industrialization and urbanization, huge amount of wastewater is generated on daily basis. Several hazardous pollutants are present in wastewater therefore it is very necessary to treat the wastewater before its use and discharge and it also becomes very evident to treat wastewater in order to fulfil the basic needs of freshwater. Moreover, among several pollutants, heavy metal present in the wastewater have severe hazardous impact on human being as well as on environmental, therefore removal of heavy metals from wastewater must be done before its utilization. There are various treatment techniques for the removal of heavy metals from wastewater viz. adsorption, ion exchange, solvent extraction, precipitation etc. But due to have some limitations like low efficiency, less economical, more energy consumption, non-ecofriendly etc. these methods are not so much effective. Membrane process is one of the effective methods for wastewater treatment and it also overcomes these limitations. Now a day, liquid membrane emerges as an efficient technique among membrane separation process. The present review paper deals with the type of liquid membranes used to specifically remove the heavy metals such as cadmium and cobalt from wastewater.
