Using methods
- Mix it and water as the proportion of 1:3 (weight) and stir for 30 minutes. When the product is fully dissolved, add 30-40 times water to dilute it. The more the solution adding, the better the purification effect has. The diluted solution might be used up in 8 hours as well.
- According to the different turbidity and season of raw water, the most proper adding amount is 5－8kg/KT for (500°)turbidity. It is better to test before using and then use.
Dosage
| Raw water turbidity | 100－250 | 400-500 | 1000-5000 | 7500 |
| Dosage(kg/kT) | 4 | 8 | 15 | 20 |
| Turbidity | 3 | 5 | 6 | 8 |
