Polyaluminium Chloride - Process, Properties and Functions

Polyaluminium chlorides are synthetic polymers dissolved in water. They react to form insoluble aluminium poly-hydroxides which precipitate in big volumetric flocs.The flocs absorb suspended pollutants in the water which are precipitated with the PAC and can together be easily removed.

Polyaluminium chloride (PAC) dosing | PWTAG Technical Notes

Because there is less aluminium content there is less aluminium in the backwash water. Furthermore, aluminium residuals are minimised. The lower aluminium content products have a higher basicity, so the best advice that PWTAG can give is to use the same dosing rate for all grades of PAC, that is 0.1ml/m3 of the total flow rate.

Aluminium chlorohydrate - Wikipedia

Aluminium chlorohydrate is a group of water-soluble, [1] specific aluminium salts having the general formula Al n Cl 3n−m( O H)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification . In water purification, this compound is preferred in some cases because of its high charge, which makes it more effective at

Inorganic Polymer Flocculants? All you need to know about PAC

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.
