Synthesis and characterization of polyethersulphone asymmetric nanofiltration membrane for batik wastewater treatment

Abstract

Batik wastewater contains high concentration of pollutants such as high colour, carcinogenic dyes, and toxic heavy metals, which required extensive treatment before being discharged into environment. This effluent is the one of most difficult to treat due to its synthetic origin and complex molecular structure of dye. The need of an environment with a minimum of pollutant has brought the need of new and useful clean technologies for the industrials production. Removal of colour and dyes from wastewater using conventional techniques are difficult and costly. Due to easy and simple operation required as well as high selectivity achieved, separation using membrane technology has becoming promising alternatives to treat colour wastewater.
