What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) has emerged as a valuable and versatile tool in water treatment processes, it plays a crucial role in making water safe for consumption, industrial use, and environmental preservation. Why we use Poly Aluminium Chloride (PAC) for water treatment?

Why is poly Aluminium chloride used in wastewater treatment?

Coagulation: Poly Aluminium Chloride’s initial role in wastewater treatment is coagulation. As it is introduced into the wastewater, Poly Aluminium Chloride disrupts the electrostatic repulsion among particles, thereby causing them to aggregate.

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

How does polyaluminium chloride affect wastewater treatment equipment?

After the use of Polyaluminium Chloride (PAS), the content of iron, manganese and other heavy metals in water is lowered, which has a little corrosive effect on wastewater treatment equipment.

What is the difference between polyaluminium chloride and Pac?

Polyaluminium chloride on the other hand, possesses lower doses of aluminium. It leaves a significantly fewer aluminium traces in the water, as well as sludge by-products. PAC is characterized by the degree of basification (%), which is the concentration of hydroxyl groups relative to aluminium ions.
