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 is high-purity poly-aluminum chloride (PACL)?

Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high–purity PACl are needed.

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

What happens when polyaluminum chloride is dissolved in water?

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. The flocs form fast and coarse with high activity, and settle quickly, so as to achieve the purpose of decomposing and purifying sewage.

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 are the synthesis parameters of aluminum chloride hexahydrate?

The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
