Polyaluminium Chloride (Polyaluminium Chloride) referred to as PAC.It is usually called basic aluminum chloride or coagulant, etc. It is a water-soluble inorganic polymer between ALCL₃ and AL(OH)₃. The general chemical formula is [AL₂(OH)_nCL_6-n]_mwhere m represents the degree of polymerization and n represents the neutrality of the PAC product. 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, flocculation and precipitation speed is fast, suitable 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.

How to use:
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 raw water turbidity is 100-500mg/L, the dosage per thousand tons is 10-20kg.
Packaging and storage:
1. Lined with plastic bags, the outer layer is packed in plastic film woven bags, each bag weighs 25kg.
2. Store in a cool, dry place, protected from sunlight and rain.
