What is polyaluminium chloride (PAC)?

Polyaluminium chloride (PAC) is a widely used water treatment chemical. It has a wide range of PH adaptation and it is not easy to produce color or other side effects. After the use of poly aluminum chloride, the content of iron, manganese and other heavy metals in water is low, which has a little corrosive effect on the equipment.

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

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.

What is Longwater® polyaluminium chloride (PAC/PACL)?

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.

What is brown PAC chemical?

Brown PAC chemical is generally mainly used for sewage treatment. The raw materials are calcium aluminate powder, hydrochloric acid, bauxite and iron powder and the production process adopts the drum drying method. Because of iron powder, the color is brown. The more iron powder is added, the darker the color.
