What does PAC stand for in water treatment?

Clear to slightly yellow in colour it is also referred to as PAC, PAX, or Polyaluminium Hydroxide Chloride Sulphate Solution. What is the use of Poly aluminium chloride? Poly Aluminium Chloride (PAC) is most commonly used in the water treatment industry as a coagulant.

What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) is most commonly used in the water treatment industry as a coagulant. It is characterised by the degree of basification – the higher this number the higher the polymer content which equals a more efficient product in the clarification of water products.

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

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.

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

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.
