Description

Polyaluminium Chloride is an acidic solution. Classified as corrosive at higher concentrations, it is typically yellow in colour. It is miscible with water at all concentrations although dilute solutions hydrolyse to precipitate Aluminium Hydroxide (Al(OH)3).
Polyaluminium Chloride is not a single product, but a spectrum of polymers which are characterised by their strength (usually in % Al2O3) and basicity – the latter gives an indication of the polymeric composition of PAC.

Product Information

The main use of Polyaluminium Chloride is in water treatment:

Drinking water treatment – coagulant
Waste water treatment – coagulant and precipitant
Process water treatment – coagulant
Effluent treatment – coagulant
Swimming pool water treatment – clarification and filtration aid
Manufacture of paper
