Polyaluminum Chloride

Generally referred to by its more commonly known name Aluminium chlorhydrate, this aluminum salt is used in cosmetics such as antiperspirant, and as a coagulant in water purification processes. Due to its high charge, polyaluminum chloride is extremely effective at destabilizing and removing suspended materials from water without significant impact to the treated waters pH when compared to other aluminium and iron salts. Polyaluminum chloride is generally manufactured in a process that reacts aluminum with hydrochlorice acid to produce byproduct salts. However, this process generally creates potential for an explosion hazard due to the hydrogen that is produced during the hydrochloric acid and aluminium reaction, so the general practice is to prepare a solution of aluminum chlorohydrate by reacting aluminium hydroxide with hydrochloric acid instead. The ACH product is then reacted with aluminum ingots at 100 Celsius using steam in an open mixing tank. This prevents the pressurized buildup of highly explosive hydrogen gas inside a pressurized mixing container.
