Abstract

Wastewater is a major environmental weakness throughout the world. Mainly, the increment of textile industries causes the increment of wastewater in the environment which is the most serious threat to living organisms. The textile industries use different types of synthetic and natural dyes for their functions and discharge large amounts of highly colored wastewater. This highly colored textile wastewater harshly affects human or living creature health as well as photosynthetic function in the plant. It also has an impact on aquatic life due to low light penetration and oxygen consumption. So, this wastewater must be treated before its discharge. Among many treatment techniques, three promising methods such as adsorption, biodegradation and advanced oxidation processes (AOPs) have been discussed in this paper. In comparison, highly recommended methods are the biological method and AOPs, especially Fenton chemistry.
