Poly Aluminium Chloride (PAC)
Poly Aluminium Chloride (PAC) is an inorganic polymer coagulant that is very effective in the water treatment, wastewater treatment, and other industrial purification systems.
It is an aluminum-based chemical compound, which is pre-hydrolyzed and has been found to have a better coagulation effect as compared to conventional chemicals such as alum.
PAC can be used in liquid and powder form and has been known to exhibit high charge density, rapid floc development, low levels of sludge and good performance over a very wide pH range.
It is among the favorite water treatment chemicals with municipal corporations, industrial water treatment plants, and commercial water treatment corporations.
