"AAA" PROCESS HELPS TREAT 1.5 MLD OF HIGHLY COLOURED TEXTILE PROCESS EFFLUENT

A.T.E. Envirotech ETP for textile manufacturing

Background

This Italian textile company manufactures premium yarn-dyed fabrics. Their Western Maharashtra facility is well-equipped with modern processes for dyeing yarn, warping, sizing, and weaving.

Challenge

The client already had an Effluent Treatment Plant (ETP) for treatment of 1.5 MLD of process effluent, which was characterized by its high colour content due to their use of vat dyes. The problems faced by the company for treating effluent in their existing ETP included:
Extensive use of chemicals, high amount of sludge generation, and high sludge handling and disposal cost.
Inconsistencies in effluent discharge characteristics, leading to challenges in meeting the discharge norms set by the Pollution Control Board

Solution

A.T.E. understood the current issues faced by the company. Instead of focusing on a typical approach of providing treatment scheme to client based on characteristics of effluent, A.T.E. adopted a scientific approach and undertook an adequacy audit and treatability study of the generated effluent. These studies helped finalise A.T.E.'s state-of-the-art AAA™ process, i.e. Air floatation, Anaerobic, Aerobic which helped the client overcome their challenges.

Result

• 1.5 MLD effluent treatment plant based on the state-of-the-art "AAA" process was designed, installed and successfully commissioned by A.T.E.
• Sludge generation and chemical consumption both, reduced by about 70%.
• Consistent treated effluent quality has also led to the possibility of effluent recycling in the future. This will result in considerable reduction of fresh water intake.
• This win-win situation prompted the MD of the company to comment that 'Adopting an advanced technology like "AAA" for wastewater treatment and recycle should be every entrepreneur's endeavour.'
