PAC (PAC), also known as basic aluminum chloride (BAC). By a series of different degree of polymerization of inorganic polymers composed of the main component of the highly charged polymeric chain polymerization of aluminum ions in water and colloidal particles with high efficiency electric neutralization and bridging flocculation, which can effectively remove the water turbidity, color degrees, heavy metals and trace organic toxicants. use The product can sterilization, deodorant, fluorine, aluminum, chromium, oil, turbidity, in addition to heavy metal salts, except for radioactive contaminants, has a variety of water purification process of a wide range of uses. 1, water treatment: drinking water, industrial water, mining and oil field injection water purification flocculation. , 2, industrial wastewater treatment: such as wastewater treatment and sludge dewatering and sewage treatment and dyeing, leather, paper,, coal washing, metallurgy, heavy metals, food industry, chemical industry and so on. 3, industrial production applications: paper sizing precipitating agent, bleaching and dyeing, ceramic adhesive, cement accelerator, hardener precision casting, refractory adhesive, refined glycerin, wrinkle-free fabric, medicine, and other industries, waste water can be recycled use. 4, not in refining industry, for no water separation, the effect is very good. Features 1, floc forming fast, good activity, good filtration. 2, without adding alkaline additives, such as the case of deliquescence, the effect is the same. 3, adapted to a wide PH value, adaptable and versatile. 4, treated water, less salt. 5, can remove heavy metals and radioactive substances to water pollution. Using the methods and precautions 1, the solid products to be dissolved into an aqueous solution of dosing: (1) The solid product 1: 3 was dissolved in water after the liquid, together with 10-30 times of water diluted to the desired concentrations (greater the source water turbidity, the more diluted the secondary water). (2) an amount according to different raw water turbidity, determination of optimal dosage, general raw water turbidity in 100-500mg / L, the dosage per thousand tonne 10-20kg 2, the liquid product is usually diluted with water to about 1% Al2O3 content dosing. 3, moisture does not affect the results. But do not let them try to damp, moisture easily dissolved.
