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 powder or liquid?

Powdered PolyAC is available as a white powder which comes in 20 or 25 kg bags. Liquid PolyAC is usually sold as a 34% w/w solution, either via bulk tanker, or in smaller containers such as 20 L jerry cans, 200 L drums, or 1000 kg intermediate bulk containers (IBCs). Polyaluminium chloride is dosed as a liquid solution.

Why is polyaluminium chloride used in aquaculture?

The role of polyaluminium chloride is to increase the soil moisture content, inhibit the formation of soil crusts, as well as increase water infiltration. Used in aquaculture. The addition of PAC coagulant can precipitate and remove a large amount of organic matter in the water body. Would like The Quotation?

What is poly aluminum chloride used for?

Used in water treatment. With the properties of adsorption, aggregation and precipitation, Poly aluminum chloride is excellent coagulant in sewage treatment, industrial wastewater treatment, drinking water treatment, circulating water treatment, etc. Used in papermaking industry.

What are the advantages of spray drying polyaluminium chloride?

With the advantages of high stability, wide adaptability, fast hydrolysis speed, strong water absorption, fast and large flocculation formation, low turbidity and super dehydration, spray drying polyaluminium chloride has better performance in drinking water treatment and wastewater treatment.

How to use polyaluminium chloride PAC coagulant in sewage treatment process?

Most industries need to use polyaluminium chloride PAC chemical in the sewage treatment process. The precipitation rate of PAC chemical is much faster and the precipitation effect is better. The use method of PAC coagulant is to dissolve it in a certain proportion and then add it to water.
