Application of Polyaluminium Chloride

Polyaluminium chloride is cheap and widely used. When the water temperature is low, it can still maintain a stable precipitation effect. Its alkalinity is higher than other aluminium salts and iron salts, and its corrosion to equipment is less. Polyaluminium chloride is an inorganic polymer flocculant. Through the action of hydroxyl ion functional group and polyvalent anionic polymerization functional group, macromolecule can be produced, which can be used in industrial water treatment and industrial circulating water treatment, coal mine scouring wastewater and ceramic industrial wastewater recovery and reuse, printing and dyeing factories, leather factories, breweries, meat processing factories, pharmaceutical factories, paper mills, coal washing, metallurgy, mining areas. And the treatment of wastewater containing fluorine, oil and heavy metals.

1. In mining, coal preparation industry can be used as mine waste and clarifier of coal washing wastewater.

2. In the paper industry, paper can be used as dry strength agent, preservative and filter aid, which can greatly improve the quality of paper, save costs and improve the production capacity of paper. With inorganic salt ions, fibers and other organic polymers electrostatic bridge, direct, in order to improve the physical strength of paper, in the deinking process can play an important role in flocculation.

3. As a flocculant, it is mainly used in industrial solid-liquid separation processes, including precipitation, clarification, concentration and sludge dewatering. Its applications include: municipal sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgical industry, mining industry, bleaching and dyeing industry, sugar industry and various industrial wastewater treatment. It is used in the dewatering process of sludge deposited in sludge from municipal sewage and meat, poultry, food processing wastewater treatment.

4. The drainage system of asbestos-cement products which can be formed by fiber slurry (asbestos-cement products) has been improved, so that the strength of the blank can be increased, and the bonding ability and fiber additives can be improved in the insulation board.

5. Purification in phosphoric acid to help wet-process phosphoric acid gypsum separation process.

6. It can be used to treat printing and dyeing wastewater, leather wastewater, oily wastewater, turbidity and bleaching to meet discharge standards.

7. The flocculant used in water treatment of waterworks is effective and low cost, especially when combined with inorganic flocculant.

It should be noted that the preparation and storage of polyaluminium chloride PAC in Zhengzhou Yucai Phosphate Chemical Plant should be carried out in enamel, galvanized or plastic barrels. It should not be in contact with iron products. It must be kept in dry, moisture-proof and heat-proof places. During storage and transportation, toxic substances should be prevented from contaminating and damaging, and packaging should not be damaged.

Polyaluminium chloride products should be evenly and slowly added into the dissolver with stirring and heating measures. Large agglomerations and long-term severe mechanical shearing should be avoided. Solid products should be dissolved into liquids by adding water at 1:3 and then diluted into the required concentration by adding 8-10 times of clear water. The dosage can be determined according to the different turbidity of raw water. The effect of dropping this product at the water discharge outlet is more remarkable.

Yucai Phosphate Chemical Plant specializes in producing: sodium hexametaphosphate, sodium pyrophosphate, sodium tripolyphosphate, sodium hydrogen phosphate, industrial phosphoric acid, trisodium phosphate, aluminum dihydrogen phosphate, solid aluminum dihydrogen phosphate, liquid aluminum dihydrogen phosphate, sodium dihydrogen phosphate and other phosphate series products after more than 30 years of continuous pursuit and development, relying on skilled chemical technology and product development, equipment updating and many universities. Established a good cooperative and sharing relationship, in the chemical industry played a (Yucai phosphate) brand!
