Summary Of Product:

Activated alumina drinking water defluorination has a large fluoride removal capacity, good physical performance, high strength, non-toxic, tasteless characteristics.

It does not change soft in water soaking ,not expanding and  not breaking.

It is used completely reliable, easy to regenerate, long life, fluoride removal effect is significant.

It can be used as drinking water fluoride removal or other industrial devices.

Activated alumina drinking water defluorination is also a defluorinating agent for high fluoride water. 

It is a molecular adsorbent with large surface area.

The product has a large contact area with water, a surface area up to 320 m2 / g, and a large number of micropores, which ensures a strong adsorption capacity for fluoride ions in water and a high capacity for fluoride removal.

And because of its uniform particle size, high mechanical strength and strong hygroscopicity, it remains in its original state after water absorption, non-toxic, tasteless, odorless, and insoluble in water and organic solvents. 

It is very suitable for use in the water treatment industry to reduce the fluorine content in water.

Precautions:

Before the raw water contact filter material, it should be reducing the pH value.

Its reduction value should be determined through the technical and economic comparison.

It generally should be adjusted to 6.0 ~ 7.0. Raw water 

Activated alumina can be added sulfuric acid, hydrochloric acid, acetic acid and other acidic solutions or added carbon dioxide gas to reduce the pH value.

The added amount should be calculated according to the alkalinity and pH value of the raw water or determined by test. 

The filter speed of the filter tank can be adopted in the following two ways.

(1) When the inlet pH value of the filter is greater than 7.0, the intermittent operation mode should be adopted. The designed filter speed is 2 ~ 3 m/h, the continuous operation time is 4 ~ 6 h, and the interval is 4 ~ 6 x.

(2) When the inlet pH value is less than 7.0, continuous operation can be adopted, and the filtration rate is 6 ~ 10 m/h. The flow of raw water through the filter layer can be bottom-up or top-down. 

When sulfuric acid solution is used to adjust the pH value, the top-down approach should be adopted. When carbon dioxide is used to adjust pH value, the bottom-up approach should be adopted.

The fluoride content of the effluent from a single filter at the end point of the defluorination cycle can be slightly higher than 1 mg/L, and the fluoride value at the end point should be determined according to the mixing adjustment ability, but the fluoride content of the mixed treated water should not be greater than 1.0 mg/L.
