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.

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

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

What is polyaluminium chloride production?

PolyAluminium Chloride production is one of the most exigent process for glass-lined equipement due to its high corrosive and abrasive effect. That's why, the experience and the qualification of De Dietrich Process Systems allow to meet qualitatively those process requirements.

Can PAC be prepared from aluminum chloride solution?

PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [16, 21], sodium hydroxide [, , ] and sodium aluminate .

Why is PAC used in papermaking?

PAC is used in the papermaking industry to increase drainage rates in neutral and alkaline processes, as a retention aid, to increase sizing efficiency and to reduce cationic demand. In 1884, Pfaudler invented the technology of corrosion resistant, glass-lined steel (Glasteel®) and is the leader still today in this technology.
