Polyaluminium chloride (PAC) dosing | PWTAG Technical Notes
This note clarifies the application and dosing rates for the various different grades of polyaluminium chloride being sold in the UK. Background. Filtration through a porous medium such as a sand bed is an efficient and cost effective means of reducing water turbidity. But sand filters are very limited in their ability to remove Cryptosporidium.

CN105236531A - Poly aluminum chloride preparation method
Anhydrous aluminium chloride is hygroscopic, having a very pronounced affinity for water. It fumes in moist air and hisses when mixed with liquid water as the Cl − ligands are displaced with H 2 O molecules to form the hexahydrate [Al (H2O)6]Cl3. The anhydrous phase cannot be regained on heating the hexahydrate.

Coagulation and Flocculation in Water and Wastewater
Material for this article was largely taken from reference 1. Coagulation and flocculation are essential processes in various disciplines. In potable water treatment, clarification of water using coagulating agents has been practiced from ancient times. As early as 2000 BC the Egyptians used almonds smeared around vessels to clarify river water.
