How can we quickly determine the quality of PAC? Polyaluminum chloride is one of the most important chemicals in water treatment chemicals, and the type of polyaluminum chloride is also very large. It can be used by experts to judge the quality of polyaluminum chloride, and can accurately determine whether to treat sewage or How to distinguish the quality of polyaluminum chloride from the quality of polyaluminum chloride, because in some conditions do not have the test conditions, how can we quickly determine the quality of polyaluminum chloride? The easiest way is to judge from the appearance and color. First of all, to talk about the less common white poly aluminum, white polyaluminium chloride because it is called high purity Wu iron white aluminum chloride, or food grade white polyaluminum chloride, compared with other polyaluminum chloride is the quality The highest product, the main raw material is high-quality aluminum hydroxide powder, hydrochloric acid, the production process is the most advanced technology spray drying method, white polyaluminum chloride for drying paper sizing agent, sugar decolorizing clarifier, medicine , Cosmetics and precision casting and water treatment and other fields, due to the high cost of white polyaluminum chloride, so rarely used in water treatment, the general use of yellow spray-dried polyaluminum chloride instead. Yellow polyaluminum chloride raw materials are calcium aluminate powder, hydrochloric acid, bauxite, the main sewage treatment and drinking water treatment, if used for drinking water treatment raw materials is aluminum hydroxide, hydrochloric acid and a little calcium aluminate , The technician to take frame filter press technology or spray drying process, due to drinking water treatment in the country on the heavy metal has strict requirements, so both raw materials and production processes are better than the brown aluminum chloride, yellow polymer chlorine Aluminum is generally produced by drum drying or spray tower drying, powdery two solid forms. The raw material of the polyaluminum chloride is calcium aluminate powder, hydrochloric acid, bauxite, and iron powder. The production process adopts a drum drying method, and is generally mainly used for sewage treatment because the iron powder is added in excess of a certain amount The amount, also known as polyaluminum chloride at some point, has excellent results in wastewater treatment.
