Specialty chemicals company Archroma has opened its first sustainable effluent treatment (SET) facility at its textile chemical site in Jamshoro, Pakistan.

With an investment of PKR371m (US$3.5m), the facility is Archroma's biggest-ever investment in Pakistan, and enables 80% of the water used to be recovered.

It also allows effluent treatment based on zero liquid discharge, fulfilling Pakistan's very stringent National Environmental Quality Standards (NEQS) requirements.

"Archroma puts a lot of time and engagement in developing chemical solutions that help our customers use less water," noted Alexander Wessels, CEO of the Archroma Group.

The SET 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 a COD (Chemical Oxygen Demand) and TDS (Total Dissolvable Solids) of less than 75 ppm. 

The Jamshoro site is one of the biggest textile chemical sites within Archroma. It produces dyes, chemicals, emulsions and pigment dispersions for the textile, leather, paper and coatings industries.
