In the petrochemical industry, fertilizer industry, widely used as a catalyst, catalyst carrier. Activated alumina, in turn, has adsorptive properties and is therefore used as a desiccant for gases and liquids, as a sorbent for gas purification, as a fluoride removal agent for drinking water, as a color and odor eliminator for industrial effluents.
Can be used in conjunction with household fluoride removal tank, is ideal for drinking water fluoride removal device in the family. The de-fluoride filter can also be used with water purification plant fluoride device or industrial equipment supporting the use of. Household de-fluoride device de-fluoride filter activation: Configure the aluminum sulfate solution (3 liters of water, 0.3kg solid aluminum sulfate), the alumina fluoride filter into the solution, soak for 5-10 hours immersion immersion When appropriate mixing), and then washed with water 3-5 times, each time about 2 liters of water, or by adjusting the PH regeneration, PH control at 7.5. Activated alumina fluoride filter can be used continuously for 6-8 years, when the surface appears brown, the effect of fluoride removal significantly reduced, the Department of water pollution caused by impurities, it is best to deal with semi-annual 3% diluted hydrochloric acid once, its The same method of operation and regeneration.
