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.

What is powdered polyaluminium chloride?

Powdered polyaluminium chloride is produced from the reaction of hot HCl gas with an aluminium substrate producing a dry material. Powdered PolyAC is available as a white powder which comes in 20 or 25 kg bags.

What is the price trend of polyaluminum chloride?

Domestic mainstream quotations for industrial polyaluminum chloride were 2373.75 RMB/MT on March 29. The Chinese market had mostly stayed stable.

How to manufacture polyaluminium chloride?

Method for manufacturing polyaluminium chloride with aluminum vanadine and calcium aluminate powder CN104671269A(en) 2015-06-03 Method for producing polyaluminum chloride from hydrogen chloride waste gas and aluminum salt water waste liquid generated from anthraquinone synthesizing production

Why did polyaluminium chloride prices rise in Q1 2021?

Due to a persistent lack of feedstock chemicals and interrupted production activity, polyaluminium chloride prices rose dramatically across the region.
