Note: mass fraction of ammonia nitrogen, arsenic, lead, cadmium, mercury, hexavalent chromium  etc impurity is  by 10.0%Al2O3

Products performance:

1,  is a kind of inorganic polymer flocculant, because the hydroxyl ions bridge function and multivalence anionic polymerization action generated bigger molecular weight , higher charge inorganic polymer water disposal reagents.

2, after purification, water quality better than minum sulfate etc inorganic flocculant , water purification cost lower than other inorganic flocculant .

3, flocculation body form quickly and settlement fast.

4, adapt to wide water pH value 5.0-9.0

product usage

1, industrial water purification and sewage treatment.

2, urban sewage and sludge treatment.

3, cosmetic raw materials.

4, catalytic carrier.

5,paper sizing

Product processing method：

Dosing quantity depending on the different water quality , generally  dosing quantity for water purification: solid products 3 -30g per ton water consumption;  Liquid products  10 - 100 g per ton water consumption.

Pakage: Solid products is packed 25kg per double lining and woven bags; Liquid products is transported by tank car.

Products guarantee period:Solid products 12 months,liquid products 6 months.
