Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts.

| Description | Yellow Powder | ||
The large amount of sulfide ions present in oilfield sewage is not only very harmful to the surrounding environment, but can also induce local corrosion and stress corrosion cracking of metal equipment. Using polyaluminium chloride for desulfurization in oilfield wastewater treatment can achieve obvious results. Polyaluminum chloride has a wide pH range, low cost, and good safety. Electrochemical methods are used to oxidize sulfur ions into elemental sulfur, and then polyaluminum chloride is used as a flocculant to desulfurize and treat oilfield wastewater.
