Poly Aluminium Chloride Brown Yellow White PAC 28%-30% Polyalumina Chloride For Water Treatment
Poly Aluminium Chloride is a solid powder. The color of polyaluminum chloride varies depending on the content and basicity, brown, yellow and white. These three colors of polyaluminum chloride are very water-soluble and dissolve immediately after entering water. During the dissolution process, hydroxide ions release a large amount of positive charges to adsorb negatively charged ions in the water, and the flocs are formed quickly and coarsely, with high activity and precipitation. Fast, achieve the purpose of decomposing and purifying sewage, and the purification effect of high turbidity water is obvious.
Brown PAC: The raw materials of brown polyaluminum chloride are calcium aluminate powder, hydrochloric acid, bauxite and iron powder. The production process adopts the drum drying method, which is generally mainly used for sewage treatment. Because iron powder is added to it, the color is brown. The more iron powder is added, the darker the color. If the iron powder exceeds a certain amount, it will be sometimes Known as polyaluminum ferric chloride, it has an excellent effect on the surface of sewage treatment.
Yellow PAC: The raw materials of yellow polyaluminum chloride are calcium aluminate powder, hydrochloric acid, and bauxite. It is mainly used for sewage treatment and drinking water treatment. If it is used for drinking water treatment, the raw materials are aluminum hydroxide powder, hydrochloric acid and a little bit. Calcium aluminate powder adopts a plate and frame filter press process or a spray drying process. Due to the strict requirements on heavy metals in drinking water treatment countries, both raw materials and production processes are better than brown polyaluminum chloride . Yellow polyaluminum chloride is generally produced by drum drying or spray tower drying, and has two solid forms, flakes and powders.
White PAC: White polyaluminum chloride is called high-purity iron-free white polyaluminum chloride, or food-grade white polyaluminum chloride. Compared with other polyaluminum chlorides, it is the highest quality product. The main raw materials are high-quality The production process of aluminum hydroxide powder and hydrochloric acid is the most advanced spray drying method in China. White polyaluminum chloride is used in papermaking sizing agent, sugar decolorization clarifier, leather tanning, medicine, cosmetics, precision casting and water treatment and other fields. Because of the high cost of white polyaluminum chloride, it is rarely used in water treatment. Generally, yellow spray-dried polyaluminum chloride is used instead.

1. Brown polyaluminum chloride: The brown polyaluminum chloride was born to meet the needs of industrial sewage. The brown polyaluminum chloride is because the content of iron is higher than that of the yellow polyaluminum chloride and the white polyaluminum chloride, so it has a color The difference. Brown polyaluminum chloride is effective for sewage with low temperature, low turbidity and high algae. It is mainly used in industrial sewage treatment, urban water supply, industrial water supply purification and other aspects. The price of the three is the cheapest.
2. Yellow polyaluminum chloride: The content of yellow polyaluminum chloride is about 29%-30% (the actual detection content is about ±1), which is mainly used in industrial water supply, industrial wastewater, industrial water recycling and urban sewage treatment. The yellow polyaluminum chloride powder is fine, uniform, good flocculation effect, stable quality, small dosage and low cost. Also loved by the majority of users.
3. White polyaluminum chloride: White polyaluminum chloride is generally used in food, drinking water, urban water supply, water purification for precision manufacturing, paper industry, medicine, sugar refining, cosmetic additives, daily chemical industry, etc.Due to its high purity, it is also called drinking-grade polyaluminum chloride PAC.. Naturally, the price is also the most expensive. It is not that white polyaluminum chloride cannot be used in industry, mainly because of price factors.
