Textile wastewater treatment

The water consumption had increased significantly due to increase in production capacity. Since treatment process involved lot of chemical treatment, disposal of chemical sludge was an issue. Water consumption had also significantly increased.

We designed and installed start-of-art treatment process for treating and recycling entire wastewater. Innovative treatment process was developed to avoid use of any chemicals in the treatment process. A scheme to use flue gas to neutralise pH from 11.5 to 7.0 in wastewater. This innovative process of use of flue gas has resulted in elimination of use of acid, chemicals and reduction in CO2 emission to atmosphere. After proper homogenisation, the effluent is fed to anoxic tank to remove ammonia followed by advanced membrane bio-reactor (MBR).

MBR permeate is stored in a tank, which is further treated through two stage RO process. Energy recovery technology is used in RO system to optimise energy consumption.
