Activated alumina ball use

In petrochemical and chemical fertilizer industries, it is widely used as catalyst and catalyst carrier. Modern water purification activated alumina has adsorption properties, so it is used as a desiccant for gases and liquids, an adsorbent for gas purification, a defluoridation agent for drinking water, and a color and odor eliminator for industrial sewage.
It can be used in conjunction with household defluoridation cylinders, and is an ideal drinking water defluoridation device for families. The filter material for defluoridation can also be used in conjunction with a defluoridation device in a waterworks or an industrial defluorination device. Activation of defluoridation filter material for household defluoridation device: configure aluminum sulfate solution (3 liters of water, 0.3kg solid aluminum sulfate), put aluminum oxide (AL2P3) defluoridation filter material into the above solution, soak for 5-10 hours and discard. liquid (stir properly when soaking), and then wash with clean water 3-5 times, each time with about 2 liters of water, or regenerate by adjusting the PH method, and the PH value is controlled at 7.5. Activated alumina defluoridation filter material can be used continuously for 6-8 years. When the surface appears yellow-brown, the defluoridation effect will be significantly reduced. The operation method is the same as the regeneration method.
