The appearance of spray polyaluminum chloride products is high-grade white, mid-grade light yellow powder, which is a new process product of polyaluminum chloride. The acidity of spray polyaluminium chloride is lower than that of other inorganic flocculants. Polyaluminium chloride due toSprayGood drying stability, wide adaptation to water, fast hydrolysis speed, strong adsorption capacity, large alum flower formation, fast precipitation, low turbidity of effluent, good dehydration performance, etc., in the case of the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially in the case of poor water quality, the dosage of spray drying products can be reduced by half compared with the drum drying polyaluminum chloride, which not only reduces the labor intensity of workers, but more importantly, reduces the water production cost of users. In addition, spray drying products can ensure safety, reduce water accidents, and be very safe and reliable for residents' drinking water.
The characteristics of spray-dried PAC polyaluminium chloride depend on the operating principle of the pressure spray. The aluminium chloride produced by the pressure spray drying process is small porous or hollow particles, which exhibit dustproof and smoothness. Due to its better contact with the water to be treated, its wettable and water treatment speed are stronger than other powdered products. Spray production not only dries polyaluminium chloride, but also turns it into tiny particles. Polyaluminium chloride is a water-soluble substance and exhibits good thermal stability and solubility.
Differences compared to ordinary polyaluminium chloride products:
1. The difference between the production process and ordinary polyaluminum chloride:
Spray drying: liquid raw materials - pressure filtration - spray tower spray drying - finished products.
Ordinary drying: liquid raw materials - placement - drum drying - finished products.
2. The difference between the use effect of ordinary polyaluminum chloride products:
Strong absorption, fast and large flocculation formation, low turbidity, and super dehydration. For the same water quality, spray drying products are smaller than other products, especially for highly polluted water quality, spray drying products only need half of the amount of drum drying products, which not only reduces labor intensity, but also reduces the cost of customers. In addition, too much spray drying product will not cause pollution, which can avoid accidents and ensure the safety of drinking water quality.
