Abstract
Tirupur district is an important textile industry region; it is the fifth largest collection of urban areas and fourth largest city by its area located in Tamil Nadu. The city of Tirupur is virtually the knitwear capital of India. It is located about 460 km from the state capital Chennai and 50 km from Manchester of South India. The dyeing industries are the backbone of the textile industry present in Tirupur. Toxic compounds are present as liquid waste from the textile industry. The river water becomes unfit for irrigation and drinking due to its contamination by the toxic compounds. Since river water is used for agricultural purposes and as drinking source and also for household activities by the locality people in the city, it is not a good practice to allow this chemical waste into the water body. Suspended solids particles in water may choke the fish gill which leads to their death or reduces their growth rate. It also reduces algae growth and diminishes their ability to produce food and oxygen. So, proper treatment of liquid wastewater and pollution due to this liquid waste must be controlled by the authorised authority by preventing the discharge of textile wastewater into water bodies. The case study was proposed to design the wastewater treatment plant in the city of Tirupur to reduce the industrial pollution caused by the dyeing industries and sewage wastes.
