Use for metallurgy, electric power, leather, pharmaceutical, printing and dyeing, paper, chemicals, such as sewage treatment industry, which formed floc coagulation effect (also known as alum) is fast and large particles and heavy, quick settlement. Applicable PH value in the range of 5 to 9, has to use less, low cost, high activity, easy operation, wide adaptability, low corrosive characteristics. Performance 1, hydrolysis speed, hydration weak. The formation of alum dense settlement rate. By the temperature change is small, meet shearing force in the flow process requirements. 2, the solid product is brown, reddish-brown powder, easily soluble in water. 3, PAFC can effectively remove the water after the source of aluminum ions and aluminum salts in water coagulation state residual free aluminum ions. 4, for a wide range of drinking water, industrial water, domestic water, sewage and industrial wastewater treatment. 5, less medication, the treatment effect is good, than the other coagulant cost savings of 10-20%. 6, PAFC use and packaging applications and essentially the same precautions with the PAC. Purifying Purifying promotion to improve water quality to people's life, health, great benefits. However, also with a good water filter water purification agent. Water filter, comprising: a water filter: fiber ball, shell filter, anthracite filter selection, refining quartz sand filter, filter magnetite, manganese sand filter, limestone filter, ceramic filter material, pebbles, zeolite, garnet, stone, diamond, rare earth porcelain sand, activated alumina, coconut shell charcoal, activated carbon shell, wood powdered activated carbon, coal columnar activated carbon, granular activated carbon coal quality!
