Lesson 16 : Pollution Through Dyeing And Printing

Effluent's Character

• Wastewater discharged from a textile wet processing plant contains various types of impurities depending on the type of dyes, chemicals, auxiliaries and process used. Some of these impurities are considered toxic while some are not. Off course the toxicity or harmfulness also depends on the amount present in a certain amount of wastewater.


• The level of toxicity was considered for water intended to be discharged into river or canals. The wastewater generated in a textile wet processing industry can be recycled back for consumption in the plant or even can be used for drinking purposes but this is expensive enough. So wastewater is generated from different textile chemical processing has some physical and chemical properties. This is because the characteristics of textile wastewater for a factory are not always same which may be due to the variation of raw materials, dyes, chemicals and process.
