The proper treatment of heavily contaminated textile effluent is a complicated process. Although the technologies and methods have been developed in the last few decades, there are still many challenges to recycle the treated wastewater. As water scarcity and shortage become more pressing problems, wastewater recycling and sustainable water management is gaining more attention.

The annual water consumption of the textile industries (including cotton farming) is nearly 93 billion m3 which is almost 4% of the global freshwater withdrawal. A large portion of this freshwater turns into industrial effluents which contain a wide range of dyestuffs and chemicals. As a result, many of the production countries around the world are facing major challenges with water pollution and freshwater scarcity.
Local legislations obligate textile industries to treat their wastewater before discharging it into the environment. But in most countries, the local discharge standards are focused more on the conventional parameters, for example, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS) [Figure 1]. Unfortunately, treatment of the textile effluents that considers only these conventional parameters does not always ensure the water quality is good enough to be reused or recycled. The textile effluent with a high pollution load must go through advanced treatment before it could be recycled again into the process.
