ALOK Industries ' optimised water consumption in the textile sector in India
In order to reduce pressures on the freshwater environment, ALOK Industries Ltd has taken measures including:
- Reducing chemical consumption by using canal water;
- Rainwater harvesting;
- Water saving by recovery of condensate;
- Water recovery from blanket cooling of machines and from PSF and softener;
- Optimizing soft water supply pressure to minimize wastage of water.
In the dyeing process, where chemical effluents can despoil the quality of the water, ALOK uses eco-friendly dyes. It also makes certain that the post-dyeing effluent water is suitably treated in one of Asia’s largest effluent treatment plants before being released back into the environment as ‘near potable’ water. To reduce the depletion of groundwater usage, ALOK has installed reverse osmosis units at its plants. These recover fresh water from the treated water. Simultaneously, steam condensate recovery ensures that groundwater depletion is further reduced. ALOK also harvests rainwater at all its plants to ensure that the groundwater used in production is replenished.
