How to Use PAC Powder 30% in Water Treatment
The way of PAC powder 30% phase is simple to remember. Dilute PAC into a 5-10% solution with clean water and add it to the water source to be treated with the following dosages:
- The dosage for 1m3 of river, pond, and lake water:
+ For water with low turbidity: 1- 4g/m3 PAC
+ For water with medium turbidity: 5 - 7g/m3 PAC
+ For water with high turbidity: 7 - 10g/m3 PAC
- The dosage of wastewater treatment (making paper, textile, dyeing, food processing) from 20-200g/m3, depending on the suspended matter content and the wastewater characteristics.
