Can polyaluminium chloride be used in drinking water treatment?

Drinking grade polyaluminium chloride (PAC 30%) can be used in drinking water treatment. Polyaluminum chloride is immediately dissolved in water. During the dissolution process, hydroxide ions release a large amount of positive charges to adsorb negatively charged ions in the water.

What are polyaluminium chlorides?

Polyaluminium chlorides (PAC) are synthetic polymers dissolved in water. They react to form insoluble aluminium poly-hydroxides which precipitate in big volumetric flocs. These flocs absorb suspended pollutants in the water and can together be easily removed with the PAC.

Is polyaluminium chloride a coagulant?

Water Supply (2022) 22 (3): 2793–2802. Polyaluminium chloride (PAC) with different basicity is used as a coagulant in most drinking water treatment plants (WTP). The aluminium concentration in PAC and its hydrolysis mechanism varied with the basicity of PAC.

What is polyaluminium chloride PAC?

Polyaluminium chloride PAC is a kind of water treatment chemical with a wide range of uses. It has the advantages of fast flocculation, rapid sedimentation, good solubility and low water purification cost. As a reliable polyaluminium chloride manufacturer in China, we can guarantee the high quality and competitive price.

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 to manufacture polyaluminium chloride?
