Introduction to the main application areas of alumina balls: Alumina balls are widely used as catalysts and catalyst carriers in the petrochemical and fertilizer industries. Activated alumina also has adsorbility, and thus they are used as desiccants for gas and liquid, adsorbents for gas purification, fluoride agents for drinking water, and color and odor elimination agents for industrial wastewaters.
They can be used together with household fluoride removing cylinders, which are the ideal fluoride removal device for drinking water at home. The fluoride removal filter can also be used in combination with fluoride devices at water plant or fluoride removal devices for industrial use.
Fluoride removal filter activation in household fluoride devices: prepare an aluminum sulfate solution (3 liters of water, 0.3kg of solid aluminum sulfate), put the alumina fluoride removal filter into the solution, soak it for 5-10 hours, discard the infusion (stir appropriately in the soaking process), and then wash for 3-5 times with water; each time use about 2 liters of water, or perform regeneration through adjusting the PH; have the PH value controlled at 7.5. Active alumina fluoride removal filter can be used continuously for 6-8 years. When the surface appears brown, the effect of fluoride removal is significantly reduced, which is due to the impurities in the water; therefore, it's best to treat it with 3% diluted hydrochloric acid once every six months. The operation method is the same as the regeneration method.
