Polyaluminium Chloride (PAC) in its light yellow powder or granular form is a high-efficiency inorganic polymer coagulant widely used across municipal and industrial sectors. It bridges the gap between traditional aluminum salts (like alum) and modern synthetic polymers, offering superior water treatment capabilities.
