Recycling: Water treatment plant opened
Facility not only supports recovery of 80% of water, but also allows effluent treatment based on zero liquid discharge
KARACHI:
Archroma, a global leader in specialty chemicals, announced on Tuesday that it opened its first sustainable effluent treatment (SET) facility for a textile operational site in Jamshoro, Pakistan with an investment of Rs371 million. The facility not only supports recovery of 80% of water, but also allows effluent treatment based on zero liquid discharge, meeting Pakistan’s National Environmental Quality Standards requirements, the company said. The effluent treatment plant is spread over an area of 25 acres consisting of flocculation, equalisation, surface aeration, clarification, ultra filtration and reverse osmosis to yield colourless water with COD (chemical oxygen demand) and TDS (total dissolvable solids) of less than 75 parts per notation. Archroma CEO in Pakistan Mujtaba Rahim said: “The data from the SGS testing report indicates Archroma’s commitment towards sustainable operational excellence.” The Jamshoro site is one of the biggest Archroma textile chemical sites.

Combining all of these methods of water purification is going to produce a quality of water that will be very close to pure, and as close to pure as can be. Even systems just employing the process of reverse osmosis will provide a quality of water that is near pure, especially when combined with other filter media as the pre filtration, which is usually carbon. Using ultra filtration before the reverse osmosis process will certainly be better than carbon before the RO membrane.
