Audited Supplier Activated Alumina for Defluorinating
Products introduction:
1.Product Description
Appearance:white sphere, no odor, insoluble in water and in the majority of organic solvents.
Property: micro-path, large specific surface, high strength, stronger capacity of absorbing, stable, no soften in water, no expansion and no crack.
Activated alumina fluoride removal features:
1)Low equipment cost, low operating cost, easy management;
2)Filter material after regeneration, can be used multiple times, long life;
3)Good fluorine removal effect, small footprint.
2. Applications
As defluoriating agent, our product can be applied in defluorinating water device, which owes to its large specific surface. The power of removing fluorine is closely related with the PH value of water. When the PH is equal to 5.5, the power of absorption reaches the maximum. Hence, it can be widely used in water treatment, especially be using to combine with de-arsenic device.
