One of the World�s largest viscose fiber manufacturers, PT South Pacific Viscose has its largest unit in Purvakarta. In 2012 their water treatment plant complex consisted of several plants added to the facility according to their expansion water demand.
(A) Two clariflocculators and gravity filters of 2000 cum/hr capacity (1982).
(B) Lamella clarifier and Dynasand filters of capacity 500 cum/hr.(1994).
(C) Ultra-highrate solids contact clarifiers with Dynasand filters of capacity 500 cum/hr.
When their fifth manufacturing unit was planned, it required a dedicate Fire Water Storage Tank of 3000 cum for which there was no space available at site. Finally they decided to take one existing clariflocculator of 1000 cum/hr capacity and to convert it in to Fire Water Storage tank (FWST). The shortfall in the treated water supply was to be made-up by converting the other clariflocculator to 2000 cum/hr capacity by retrofitting it with tube settlers.
