Recent Developments of Membrane Technology for Wastewater Treatment

Abstract

The worldwide one major and important issue is the increasing shortage of freshwater. Water is polluted by various category of pollutant such as heavy metal, organic toxic chemical, dyes and others. In such situation providing better solutions for water treatment is a major challenge for researchers. Various techniques have been used in wastewater treatment applications but among those techniques the membrane technology is the most promising technology. This chapter contains recent progress of membrane technology for advanced wastewater treatment, is systematically summarize. This review includes introduction about different membrane technology such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). Current status of each membrane separation techniques, membrane cleaning techniques, challenges and promising solutions for various wastewater treatment have been discussed.
