What are polyaluminium chlorides?

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

What is alupac – poly Aluminium chloride?

(PAC) Poly Aluminium Chloride – AluPAC is a high purity product with high aluminum content. AluPAC is produced according to EN 883 (Chemicals used for the treatment of water intended for human consumption). AluPAC neutralizes the colloidal charge whereby compact flocks are formed.

What is polyaluminum chloride (PAC)?

Polyaluminum chloride (PAC): Polyaluminum chloride, known as PAC, is a blend of chemicals that can achieve the same (or better) coagulant results as alum. It was manufactured to eliminate some of the pH and alkalinity adjustments that are necessary when using traditional coagulants.
