Leading the way towards zero discharge
We continuously challenge the status quo in the deep belief that we can make our industry sustainable.
We are passionate to deliver leading and innovative solutions, enhancing people’s lives and respecting our planet. This is easy to say, more of a challenge to deliver, as our customers very well know.
Archroma operates in parts of the world where the environment presents us with extremes, to which we must show respect, manage and adapt.
Archroma has been operating a site at Jamshoro, near Hyderabad, Pakistan since 1970, where we produce dyestuffs for the local and international textile industry.
After this region of Pakistan was hit by severe floods and drinking water shortages in 2010, the local Archroma team decided to make a substantial investment (c. $3.5 million US) in the Jamshoro site to make significant changes to both water quality and quantity.
Using a sequence of processes most usually found in municipal drinking water treatment facilities, the Jamshoro plant combines flocculation, equalization, surface aeration, clarification, ultra-filtration and reverse osmosis.
CLEANER WATER, LOCAL ENERGY AND BUILDING MATERIALS FROM WASTE
While each of the treatment techniques used is not new, the combination and sequence is, we believe, unique in the textiles chemical industry. The resultant recovered water is returned for use in the production facility and so significantly reduces our demand from local water supplies.
Every day, between 1,200 and 1,300 cubic meters of effluent is generated which passes through sustainable effluent treatment. Eighty percent of the water is recovered, the remaining water is lost through evaporation and results in 3 to 4 tons of dried sludge which is then incinerated. Incinerating the sludge creates steam, which is used in the production facility.
The Sustainable Effluent Treatment facility operates with zero discharge, reduced steam energy and reclaimed water for the Jamshoro site.
