1. Name Introduction

Name: High purity white polyaluminum chloride for drinking water (abbreviated as polyaluminum or PAC)

Technical standards: GB15892-2020。

2. Product Features

This product has a fast dissolution rate, is non corrosive, and has a wide range of adaptability to water quality. It has good effects on turbidity removal, decolorization, and deodorization. This product requires minimal dosage during coagulation, resulting in rapid and large formation of flocs and rapid settling. The purified water quality fully meets the corresponding standard requirements. Low water insoluble matter, low basicity, and low iron content. Easy to dissolve in water, efficient and stable purification;

3. Production process

Spray drying: liquid raw materials ---- pressure filtration ---- spray tower spray drying ---- finished products.

Raw materials: aluminum hydroxide+hydrochloric acid.

4. Different synthesis costs

Due to the advantages of spray drying products, such as good stability, wide adaptability to water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast quality density and sedimentation, low effluent turbidity, and good dehydration performance, under the same water quality, the dosage of spray drying products is reduced. Especially under the condition of poor water quality, the dosage of spray drying products can be reduced by half compared with roller drying products, which not only reduces the labor intensity of workers, but also, more importantly, reduces the water production cost of users.

5. Main technical indicators

Aluminum trioxide: during spray drying, the centrifuge evenly sprays the mother liquor into the drying tower, so that the aluminum trioxide content is uniform, stable, and easily controlled within the index range, enhancing the adsorption capacity of particles, and achieving two effects of coagulation and flocculation, which can not be achieved by other drying methods.

Salinity: During water treatment, the alkalinity, that is, the polymerization degree, directly affects the water purification effect. The centrifugal spray drying method is used to improve the polymerization degree of the product while maintaining the original activity of the mother liquor. At the same time, the alkalinity can be adjusted according to different water quality. However, drum drying is prone to damaging the degree of polymerization, resulting in a small range of product salinity and a narrow adaptability to water quality.

Water insoluble substances: The level of water insoluble substances affects the water purification effect of the comprehensive product, improves the drug utilization rate, and has a significant comprehensive effect.

6. Purpose:

Polyaluminum chloride is an inorganic polymer flocculant. Through the action of hydroxyl ion functional groups and multivalent anion polymerization functional groups, inorganic polymers with high molecular weight and high charge are produced.

(1) Can be applied to the treatment of river water, lake water, and groundwater.

(2) Can be applied to the treatment of industrial water and industrial recycled water.

(3) Can be applied to the treatment of wastewater.

(4) Can be applied to the recovery of coal mine flushing wastewater and porcelain industry wastewater.

(5) It can be applied to printing factories, printing and dyeing factories, leather factories, breweries, meat processing factories, pharmaceutical factories, paper mills, coal washing, metallurgy, mining areas, as well as the treatment of wastewater containing fluorine, oil, and heavy metals.

(6) Can be applied to wrinkle prevention of leather and fabric.

(7) Can be applied to cement solidification and molding casting.

(8) Can be applied to the refining of pharmaceuticals, glycerol, and carbohydrates.

(9) Can serve as a good catalyst.

(10) Can be applied to paper bonding.

7. Application method

Users can determine the optimal dosage of chemicals by experimenting and adjusting their concentration based on different water quality and terrain.

(1) Liquid products can be directly dispensed or diluted before dispensing. Solid products need to be dissolved and diluted before being released. Please determine the dilution water quantity based on the water quality to be treated and the quantity of products. The dilution ratio for solid products is 2-20%, and for liquid products it is 5-50% (by weight).

(2) The dosage of liquid products is 3-40 grams/ton, and the dosage of solid products is 1-15 grams/ton. The specific dosage is subject to flocculation testing and experiments.

8. Packaging and Storage

The solid is packaged in 25kg bags, with an inner layer of plastic film and an outer layer of plastic woven bags. The product should be stored indoors in a dry, ventilated, and cool place, and should not be damp.
