Poly aluminium chloride(PAC),water treatment
Polyaluminium chloride(PAC)
PAC referred to as PAC, usually referred to as Basic aluminum chloride, or coagulant, it is between ALCL3 and AL (OH) 3 between a water-soluble inorganic polymers, chemical, general formula for [ AL2 (OH) NCL6-NLm] where m on behalf of the extent of aggregation. N on behalf of PAC products neutral level. The color yellow, or yellow. Dark brown, dark gray resin-like solid. The product has a strong bridge adsorption, in the hydrolysis process, accompanied by cohesion occurs, adsorption and precipitation and other physical chemical processes. It is with the traditional inorganic coagulant is the essence of inorganic coagulant for the low-molecular crystal salt. The PAC's structure consists of multiple complex patterns varied composition, coagulation and sedimentation speed, suitable for a wide range of PH value, non-corrosive to the plumbing, water purifying effect obviously can effectively support In addition to the water-color quality SS, COD, BOB, and arsenic, mercury and other heavy metal ions, the product you are widely used in drinking fountains, industrial water and wastewater processing.
Usage:
1. According to 1:3, the solid product dissolved in liquid water, together with the 10-30 times of water diluted to the required concentration before use.
2. Dosage according to the different raw water turbidity measurement of optimal dosage, the general raw water turbidity in the 100-500mg / L, the dosage for each 1000 tons of 10-20kg.
Packaging and storage:
1. Lined with plastic bags, the outer layer of plastic film for plastic woven bag packaging, bag weight of 25kg.
2. Stored in a cool place. Dry Branch, anti-sun and rain.
