Polyelectrolyte for Kolkata leather, engineering and jute plants
Kolkata's Bantala leather complex, Howrah's foundries and engineering units, the Hooghly jute mills and Haldia's refinery all need dependable clarification.
Polyacrylamide (PAM), also known as a flocculant or polyelectrolyte, has proven highly effective in water treatment. Sunfloc is the Sun Brand PAM range, in anionic and cationic grades.
