5. Directions for Use
- Dissolve the solid product with water at a ratio of 1:3 to prepare a concentrated solution, then dilute 10–30 times with clean water to the required concentration before use.
- The optimal dosage can be determined according to the turbidity of raw water. For raw water with turbidity of 100–500 mg/L, the recommended dosage is 10–20 kg per 1000 tons of water.
6. Packaging and Storage
- Packed in 25 kg plastic film woven bags with inner plastic liners.
- Store in a cool and dry place, protected from sunlight and rain. Do not store with flammable, explosive, radioactive, or hazardous chemicals.
- Deliquescence does not affect product performance, but moisture should be avoided to prevent dissolution.
- Recommended manufacturer of Polyaluminium Chloride by the Ministry of Science and Technology and other national research authorities.
