The PAC in the water treatment agent refers to a polyaluminum chloride material which can be used for treating sewage, and can be used in the fields of paper sizing agent, sugar bleaching clarifying agent, tanning leather, medicine, cosmetics and water treatment, etc., we know How is the PAC in the water treatment agent produced by the composition and application field of the PAC in the water treatment agent? Let's take a look at it together.
1. It can be made by the roller method and processed by the roller method with calcium aluminate powder and hydrochloric acid. The color of the polyaluminum chloride produced by this method is brown or brown, and the PAC in the water treatment agent. The alumina content is not high, the water insoluble matter is high, and the price is low, which is generally used for sewage treatment.
2. It can also be produced by plate-and-frame production method. The produced polyaluminum chloride agent has high chlorine content, beige color and low water insoluble matter, and is mostly used for sewage treatment and drinking water treatment.
3. Another method with higher cost is spray drying. This method requires aluminum, bauxite, aluminum powder, aluminum hydroxide, hydrochloric acid and alumina to make PAC. The color of the produced PAC is white or yellow. The water treatment agent has high content of polyaluminum chloride, low water insoluble matter, fast dissolution rate, and high processing cost, so the price is also high for drinking water and chemical tests.
