More information

Polyaluminium Chloride (Polyaluminium Chloride) referred to as PAC. It is a water-soluble inorganic polymer between ALCL3 and AL(OH)3. The general chemical formula is [AL2(OH)NCL6-NLm], where m represents the degree of polymerization, and n represents the neutrality of PAC products. degree. The color is yellow or light yellow, dark brown, dark gray resin-like solid. The product has strong bridging and absorption performance. During the hydrolysis process, physical and chemical processes such as condensation, adsorption and precipitation occur.

The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride is composed of multi-element carboxyl complexes with variable morphology, which has fast flocculation and precipitation speed and is suitable for Wide range of PH value, non-corrosive to pipeline equipment, obvious water purification effect, can effectively remove the color quality SS, COD, BOD, arsenic, mercury and other heavy metal ions in the water. This product is widely used in drinking water, industrial water and sewage treatment field.



1. Dissolve the solid product with water in a ratio of 1:3 to a liquid, then add 10-30 times of clear water to dilute it to the required concentration before use.

2. The dosage can be determined according to the different turbidity of the raw water to determine the best dosage. Generally, when the turbidity of the raw water is 100-500mg/L, the dosage per thousand tons is 10-20kg.
