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.
