Recent Developments of Textile Waste Water Treatment by Adsorption Process: A Review

Adsorption has been known as the most acceptable method for removal of refractory compounds in textile waste water treatment. Owing to its ability in terms of physical and chemical sorption, a wide range of precursors origin from natural resources, synthesized materials and agricultural wastes as the starting materials for adsorbents purpose have been tested via adsorption technique. Over the years, scientists have begun searching for a sustainable replacement of the conventional adsorbents due to expensiveness, poor mechanical properties and limited applications. Lately, focus has been paid on the potential of locally available materials, inexpensive, easier to obtain, good mechanical properties and high adsorption capacities that can be converted into adsorbent. The present article highlights recent developments of textile waste water treatment by adsorption process. A critical discussion with regard to textile waste water characteristics, textile operation and adsorption by various adsorbent were also included in this review.
