As a new type of water treatment agent, the color of polyaluminum chloride is very different. Generally, there are brown, brown, golden yellow, light yellow and white polyaluminum chloride. The reason for this is that each manufacturer has different production processes and raw materials, and the colors produced are different. Of course, the colors are different, and the effects and applications are also different
1. Brown, brown, these three colors are products produced according to the special requirements of individual customers for water treatment, in which the iron content is higher than other polyaluminum, so the color is darker than golden yellow, which can effectively have a very good effect on low turbidity, high algae sewage, mainly used for urban sewage, industrial sewage water treatment, purification and flocculation.
2. The golden yellow raw materials are calcium aluminate powder, bauxite and hydrochloric acid. Sewage and drinking water are mainly used, which is an important link in the factory. The country has strict requirements and standards in the application of water treatment, so it is better than brown, brown and brown polyaluminum chloride in all aspects. Also known as industrial polyaluminum chloride
3. The light yellow medium high series products, second only to white polyaluminum, are mainly used for drinking water treatment. The content standard of heavy metals is very strict, the powder is fine, the particles are uniform, the flocculation effect is good, the dosage is small, and the cost is low. They are special reagents for water plants. Also known as drinking water grade polyaluminum chloride
4. The white process is very high, and can reach the edible level. It is widely used in urban water, food, medicine, sugar solution, cosmetic preparations, etc. At present, the price of polyaluminum chloride with very high purity is relatively high. It is also called high-purity polyaluminum chloride.
