Development of integrated kenaf core cellulose nanofiltration flatsheet membrane for batik wastewater / Sharifah Abdullah

Batik Industry which is similar to Textile Industry is a popular industry in Malaysia. The industry produces wastewater that is high in color and pH, and commonly release to the nearby waterbody without any proper treatment. This practice contributed to water pollution at the nearby river. Previous studies show that color and pH are the dominant pollution in batik/textile wastewater while heavy metals are also present in the effluent. Generally, most water treatment plants utilize conventional water treatment system consists of processes such as aeration, coagulation and flocculation utilizing aluminum-based chemicals known as alum. Conventional method is insufficient to treat the batik wastewater.
