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 .

Is polyaluminum chloride a stable product?

Stable product. No AlOH formation Polyaluminum chloride (PAC) and aluminum sulfate make use of agglutinative properties in the treatment of water for municipal water supplies, sewage wastewater, and industrial wastewater to adsorb (flocculate) and precipitate the fine particles and suspended solids in the processing of suspensions.

What is polyaluminium chloride?

Polyaluminium Chloride is a water purification material, inorganic polymer coagulant, also referred to as Poly aluminum, abbreviated as PAC, an inorganic polymer water treatment agent having a relatively large molecular weight and a relatively high charge is produced due to bridging action of hydroxide ions and polymerization of polyvalent anions.

Can polyaluminium chloride be applied to water with broad pH range?

Polyaluminium Chloride can be applied to water with broad pH range. Comparing to inorganic flocculants, Polyaluminium Chloride is suitable for water of broad temperature, and is functional in low temperature water. Polyaluminium Chloride reduces less basicity less, so less or no basifier needed.

How to test polyaluminum chloride PAC solution?

Test Solution Configuration according to the weight ratio (W/W), generally with 2 ~ 5%. For example, prepare 3% solution: weigh 3g of polyaluminum chloride PAC solid, put it in a 200ml measuring cylinder, add about 50ml of clear water, dilute it to 100ml scale after it is dissolved, and shake it well.

What is PAC Polyaluminium chloride water insoluble?

PAC Polyaluminium Chloride water insoluble: the use of plate and frame filter technology, the solid water insoluble mass fraction of 0.3% or less, liquid water insoluble mass fraction of 0.1% or less, to ensure the smooth flow of the user's pipeline, while improving the use of drugs, and the natural sedimentation method is not up to.
