Product type
Poly Aluminum Chloride (PAC) is a widely used coagulant in water treatment processes. It is a type of inorganic polymer that is typically produced by the hydrolysis of aluminum chloride in an alkaline medium. PAC is effective in removing suspended solids and impurities from water, making it suitable for various applications in water purification and wastewater treatment. Its enhanced performance over traditional aluminum sulfate makes it a preferred choice in many industries.
