Aluminum Chlorohydrate Introduction:
Aluminum Chlorohydrate with the molecular formula Al2(OH)5Cl·2H2O. It is an inorganic polymer compound with higher alkalinity (base degree) than polyaluminum chloride, second only to aluminum hydroxide, and is bridged by hydroxyl groups, with the highest number of hydroxyl groups in the molecule. It is a white powdery solid, and its solution is a colorless transparent liquid. The content of alumina in liquid products is more than 23%, and the content of alumina in solid products is 46% to 50%. It has strong bridging adsorption properties and is easily soluble in water. The hydrolysis process is accompanied by electrochemical, condensation, adsorption and precipitation physical and chemical processes.
Aluminum Chlorohydrate Usage:
Aluminum Chlorohydrate as a flocculant is mainly used in pure water, drinking water and domestic water supply standard water quality treatment. This product is synthesized from pure aluminum and edible hydrochloric acid through multi-process, and is an internationally recognized drinking water treatment agent.
