Products Description
Polyaluminium Chloride (PAC), CAS 1327-41-9, is a high-efficiency inorganic polymer coagulant. Solid PAC appears as yellow, pale yellow or off-white powder/granules, while liquid PAC is light yellow transparent to turbid liquid. It dissolves rapidly in water and produces polynuclear hydroxyl aluminum complexes through hydrolysis, which can adsorb and agglomerate suspended particles. It is non-hazardous goods for transport. We provide different specifications with varied basicity. Solid is packed in 25kg woven bags, liquid in plastic drums or IBC tanks. It is widely supplied for water purification and industrial wastewater treatment projects globally.

Product Application
It is commonly used for tap water, reservoir water and river raw water purification to remove turbidity, chroma and suspended impurities. It works as main flocculant for municipal sewage, printing and dyeing wastewater, papermaking wastewater and coal washing wastewater. It can also assist in phosphorus removal and heavy metal precipitation. Combined with anionic polyacrylamide, it achieves better sedimentation performance. It is widely adopted in industrial circulating water clarification, landfill leachate pretreatment and swimming pool water treatment. Different basicity grades are selected to adapt to different water quality and treatment requirements.
