The spray-dried polyaluminum chloride products offer excellent stability, wide adaptability to water bodies, rapid hydrolysis speed, strong adsorption capability, large floc formation, dense and quick precipitation, low turbidity in the effluent, and good dehydration properties. Under the same water quality conditions, the dosage of spray-dried polyaluminum chloride is reduced, particularly in poor water quality situations. Compared to the dosage of drum-dried polyaluminum chloride, it can be cut in half, thereby not only easing the labor intensity for workers but also reducing the water production costs for users. Moreover, using spray-dried polyaluminum chloride ensures safety, minimizes water accidents, and provides very reliable drinking water for residents.

The differences between spray-dried polyaluminum chloride and regular polyaluminum chloride:

Spray Drying: Liquid raw material → Pressure filtration → Spray tower drying → finished product.

High absorbency, rapid and large flocculation formation, low turbidity, and strong dehydration properties. For the same water quality, the spray-dried product requires less dosage than other products, especially for highly polluted water, only half the amount of the drum-dried product is needed. This not only reduces labor intensity but also lowers the customer's costs. Additionally, an excessive amount of spray-dried product does not cause pollution, can prevent accidental incidents, and ensures the reliability of drinking water quality.

Spray Drying Type Aluminum Chloride Production Process: Due to the even distribution of the mother liquor by the nozzle inside the drying tower, the Al2O3 content is uniform and stable, easily controlled within the specified range, enhancing the adsorption capacity of colloidal particles, and achieving both coagulation and flocculation effects, which other drying methods cannot achieve. The basicity, or the degree of polymerization, directly affects the water purification efficiency.

1. A large supply of positively charged, morphologically stable, multinuclear hydroxylaluminum complexes that effectively promote flocculation and sizing.

3. Aluminum chloride hydroxide is a pre-hydrolyzed form of aluminum chloride, with a relatively lower degree of hydrolysis. The decrease in pulp pH is less than that of aluminum sulfate.

5. Paper performance, excluding breaking length, has seen an improvement in all other indicators to varying degrees.
