Modern water purification activated alumina high performance ingredients can bring the following benefits of unshaped refractory materials: increase body density, fluidity, strength, improve two mullite production, reducing the amount of water and porosity. In addition, activated alumina can also be used as an adsorbent, desiccant, water absorption capacity, drying speed, renewable (400 -500K baking), and water does not swell, not cracking, no deformation.

Product appearance editor

Modern water purification of activated alumina white spherical porous particles, uniform size, smooth surface, high mechanical strength, strong moisture absorption, water absorption expansion does not crack after not to maintain the status quo, non-toxic, odorless, insoluble in water, ethanol, has strong adsorption of fluoride, mainly used in high fluoride areas of drinking water fluoride removal.

Activated alumina ball

Activated alumina ball

Modern water activated alumina has selective adsorption capacity for water, gas, water and some liquids. After being saturated, the water can be heated at about 175-315 DEG C to remove water and recover. Adsorption and recovery can be repeated many times. In addition to being used as a desiccant, the vapors of the lubricating oil can also be adsorbed from the contaminated oxygen, hydrogen, carbon dioxide, natural gas, etc.. And can be used as catalyst and catalyst carrier and chromatographic analysis carrier.

Product application editor

It is widely used as catalyst and catalyst carrier in petrochemical industry and chemical fertilizer industry. Modern water activated alumina has adsorption characteristics, which is used as gas and liquid desiccant, gas purification adsorbent, water defluoridation, industrial sewage color and odor elimination agent, etc..

The utility model can be matched with a household fluoride removing cylinder, and is an ideal drinking water defluoridation device in a household. The fluoride removing filter material can also be matched with a water treatment plant defluorination device or an industrial fluoride removing device. Household defluoridation device fluoride filter material activation: configuration of aluminum sulfate solution (3 liters of water, 0.3KG solid aluminum sulfate), alumina (AL2P3) fluoride filter material in the solution, soak 5-10 hours when immersion (immersion when appropriate to stir, and then rinse) 3-5 times, each about 2 liters of water. Or with PH regeneration, pH control in 7.5. Activated alumina defluoridation filter can be used for 6-8 years, when the surface appear when Tan, the effect of fluoride removal significantly reduced, this is caused by the impurities in the water pollution, so it is best to every half a year with 3% dilute hydrochloric acid treatment, the operation method and regeneration method of the same.
