Polyaluminum Chloride PAC

Polyaluminium Chloride
Chemical formula AL2(OH)NCL6-NLm

It is a kind of inorganic water-soluble polymers, between the Alcl3 and Al(OH)3.
Appearance: yellow or light yellow, dark brown, dark gray resin-like solid.
Function: the product has a strong bridge adsorption properties, in the hydrolysis process, with the condensate, and other physical and chemical absorption .

the fundamental difference between traditional inorganic coagulant and pac is that f traditional inorganic coagulant has low molecular weight crystalline salt. However, PAC is formed by the complex multiple carboxy. Therefore, the flocculation and sedimentation speed, for PH value range is wide, non-corrosive for plumbing, obvious for water purification.
it can remove t SS, COD, BOD, and arsenic, mercury and other heavy metal ions in the water. It is widely used in drinking water, industrial water and wastewater treatment.

Usage :

1. The solid product dissolved in water at 1:3, after it becomes the liquid,
Together with 10-30 times the concentration of water used after dilution to the required
2. The amount of raw water according to the different turbidity...
the general turbidity of the water in the 100-500mg / L, each dosage tons 10-20kg.
packing :inner layer of plastic bag ,outer layer of plastic film woven bag
