Activated Alumina for Water Purification
1.Activated alumina for water purification has a strong affinity for water, oxide, acetic acid, alkali and so on.
2.It is a kind of deep water adsorbent, and has a good adsorption effect on fluoride ions in water and a good defluorination effect.
3.This product also has the characteristics of high strength, low wear, constant soft, no expansion, no powder.
Product Introduction
Production Introduction:
Activated alumina for water purification is a porous,highly dispersed solid material with a large surface area,white spherical porous particles,uniform particle size,smooth surface,large mechanical strength,no swelling and cracking after water absorption,non-toxic,odorless,insoluble in water and ethanol.Placed in water can effectively absorb impurities and harmful substances in water,and has a purification effect on water quality.

Product feature and application:
Activated alumina for water purification produced by our company can be used in conjunction with household defluorination cylinders,making it an ideal drinking water defluorination device in the family.It can also be used in conjunction with the fluorine-removing device of the water plant or the fluorine-removing device for industry. Regeneration of activated alumina for household defluorinating device:configure aluminum sulfate solution (3 liters of water,0.3 kg solid aluminum sulfate),put alumina defluorinating filter material in the above solution,soak for 5-10 hours and discard the immersion liquid (soak It should be properly stirred),then washed with clean water 3-5 times,about 2 liters of water each time,or regenerated by pH adjustment method,the PH value is controlled at 7.5.Activated alumina for water purification can be used continuously for 6-8 years. When the surface appears yellowish brown,the defluorination effect is significantly reduced.This is due to the contamination of impurities in the water.The operation method is the same as the regeneration method.
