Why is polyaluminium chloride a good flocculant?

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. The corrosivity of Polyaluminium Chloride is lower, easy to transfer, handle and operate.

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 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.

What is polyaluminium chloride (PAC) used in paper sizing?

For polyaluminium chloride (PAC) used in paper sizing, the dosage is one of three parts of aluminium sulfate, which is calculated as 2-3% according to absolute dry paper, and is used in decolorization and clarification of sugar industry.

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.

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.
