Arsenic is a designated human carcinogen, contamination of which in drinking water supplies has been reported in many parts of the world, including Pakistan.
Much work has been done, both locally and internationally, on development of technologies for the removal of Arsenic from drinking waters. In spite of this, a 2017 study reported alarmingly high levels of arsenic in the groundwater of eastern Pakistan with potential exposure to an estimated 50 million people.
Arsenic levels in excess of 200 µg/l have been reported in Lahore and adjoining areas, against a current WHO MCL (Maximum Contaminant Level) of 10 µg/l.
Industry: Domestic
Application: Arsenic Removal Filtration
Location: Lahore
Arsenic in source water (left) between 50 and 100 µg/l, and product water (right) less than 5 µg/l.
PCC installed an Arsenic removal filter for factory workers’ potable water usage, based on one of US EPA’s classified BAT (Best Available Technology) for Arsenic removal using a coagulation-filtration multimedia filtration system with a specialized NSF/ANSI-61 approved media.
Source water with over 50 µg/l Arsenic was treated with demonstrated > 90% Arsenic removal, and < 5 µg/l Arsenic in the product water
