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 PAC used in water treatment?

PAC helps reduce the overall cost of water treatment by 15-30%. Compared to inorganic coagulants or flocculants, PAC is suited to broad water temperature including at low temperature. Water treated using PAC has fewer salts content and can be used for ion-exchange treatment. PAC contains lower corrosivity level and is easy to handle and operate.

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.

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.

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.

Why is polyaluminum chloride used in water treatment?

The application of poly aluminum chloride in water treatment can ensure the quality of water sources to a certain extent and reduce the harm to human health. At present, polyaluminum chloride water treatment is not only used in industrial sewage but also widely used in urban sewage and drinking water treatment. 2.
