Removal and Recovery of Pollutants from Wastewater by Using Continuous Liquid Membrane System: A Review

Liquid membrane has received significant interest among the researchers as it provides efficient technology in treating wastewater. However the used of liquid membrane only available in batch and laboratory scale and only a few can be found in the industries. The restriction were related to the instability of liquid membrane such as small interfacial area for bulk liquid membrane (BLM), membrane swelling for emulsion liquid membrane (ELM) and membrane breakthrough for supported liquid membrane (SLM). Thus, this review will discuss on the work of researchers to overcome those problems mostly in batch and laboratory scale. A few applications on continuous liquid membrane in industry application also will be addressed. Eventually, this review will provide the prospective of liquid membrane as the future continuous treatment method in wastewater treatment.
