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.

What is polyaluminum chloride (PAC)?

Polyaluminum Chloride (PAC) is one of the most efficient water treatment chemicals utilized today. It is widely used in both potable water and wastewater treatment because it provides high coagulation efficiency and it has the widest pH and temperature application ranges compared to other water treatment chemicals.

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.

Can poly aluminum chloride be applied to sewage treatment?

It can be applied to sewage treatment because it has a wide range of application to PH value and short settling time. 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.

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.

How to make polyaluminium chloride powder?

The method using aluminum chloride powder as raw material to produce polyaluminium chloride powder is most commonly used. It can be prepared by boiling pyrolysis with crystalline aluminum chloride at 170℃, adding water for curing and polymerization,and then curing and drying to get PAC powder.
