2. Product Advantage

1. Application is wide, adapting water extensively.

2. Don't need to add an alkalescence to help, if meet to deliquesce, its result is constant.

3. Become a big alum flower easily and quickly, precipitate function like.

4. Feat pH value scope compare breadth(5 9), and processing aqueous pH value and alkalinity

5. Descend behind small.when the water temperature is low, still can keep to precipitate result stablely.

6. Alkali turn one degree higher than the other aluminum salts, iron salts, erode a function to the equipments small.

7. The valid composition is high, easy to storage, conveyance.
