PAC Polyaluminium Chloride White Powder 25 KG /BAG Industrial Wastewater Treatment
Polyaluminium chloride (PAC) is an inorganic substance, an emerging water purification material, and an inorganic polymer coagulant, referred to as polyaluminium.
The color of polymeric aluminum chloride is yellow or light yellow, dark brown, dark gray resin-like solid. The product has strong bridging adsorption properties, and in the process of hydrolysis, accompanied by the occurrence of cohesion, adsorption and precipitation and other physicochemical processes.
In form, it can be further divided into solid and liquid. The solid is divided into tan, beige, golden yellow and white according to different colors, and the liquid can be presented as colorless transparent, slightly yellow, light yellow to yellowish brown. Different colors of polymeric aluminum chloride in the application and production technology also have a big difference.

The dosage of aluminum chloride in different water quality:
1. In low turbidity water, dilute the solid aluminum chloride product with tap water according to the ratio of 1:3 (by weight), and stir until completely dissolved.
2. In the life production of sewage, refer to each ton of sewage first add about 30g of polymerized aluminum chloride products. Then add the diluted polyacrylamide products (If the effect is not obvious, please reduce or increase the amount of product dosage as appropriate.)
3. In the paper mill wastewater treatment, the use of low turbidity water put in the proportion of configuration, such as the effect is not obvious can be added at discretion.
4. the turbidity of raw water in 100-500mg / L, the dosage of 5-10mg per thousand tons of water, that is, the dosage of 5-10kg, it is best to carry out a small test according to the characteristics of the water quality before use, select the optimal value, and then put into use.
