Appearance
1. Odorless light yellow to yellowish white powder or white powder.
2. Odorless transparent to yellow liquid or yellow brown liquid.
Quality Standard
1. Executive standard : GB 15892-2009.
2. Our company complies “Safety standard of manufacturing company concerning the drinking water and it’s healthy and safety products”.
3. The product complies “Safety and healthy evaluation standard of water treatment chemicals for daily drinking water”.
Features
1. Its effective content is high with low treating costs. It is suitable for daily drinking water purification for its high active degree.
2. It is with good coagulation function by forming big and dense alumen ustum particles with high precipitation speed and separating the poisonous materials from water in this way.
3. It has the advantages of rapid coagulation reaction, strong electronic neutralization and destabilization ability with long molecular chain and bridging quickly, which can overcome the difficulties of water treatment in low temperature and low turbidity condition, as well as has a better treatment effect towards iron, fluoride, arsenic and bacteria in water.
4. Higher basicity than other aluminium salt and ferric salt, excellent solubility and less corrosion to the equipment.
5. This product is produced by industrial synthetic hydrochloric acid, activated aluminum hydroxide powder, calcium aluminate powder as raw materials.
Application Area
Especially used in drinking water purification.

How to Use
Solid product:
1. The solid product can be easily dissolved. To make it fully dissolved with tap water in dissolving tank according to a certain concentration(2-5%) before use.
2. The amount of dosage should be determined by the testing, which is usually one third to a half of the amount of solid aluminum sulfate under the same conditions.
3. To prepare it to 10% solution with good stability for 30 days.
Liquid product:
1. The liquid product can be diluted with water or be added directly before use.
2. The dosage can be confirmed by a small test of the different turbidity of original water. Generally, when the turbidity of original water is 100-500mg/L, the suitable dosage is 10-20Kg per kiloton.
