The issue of the amount of acid, alkali, and sodium sulfite in the dechlorination tower

This is not necessarily the case. It is related to the free chlorine at the outlet of your dechlorination tower, as well as the amount of water that has been dechlorinated. It mainly controls the pressure and acidity of the dechlorination tower. (Remember to rate me!)
Is the flow rate of the dechlorinated brackish water stable? I experience significant fluctuations; generally, the free chlorine level before adding sodium sulfite after dechlorination is 10, and the volume of low-salt water is 38 M3
The flow rate is stable; it has little to do with dechlorination. The brackish water you get should be stable as well
Under normal conditions, about 1.5 kilograms of sodium sulfite are consumed.
“Under normal conditions, about 1.5 kilograms of sodium sulfite is consumed” – that is, per ton of caustic soda produced, approximately 1.5 kilograms of sodium sulfite is required. 5# yhhgcwb
Personally, I think it’s better to make adjustments based on actual production conditions
Factors affecting consumption: 1. Electrolysis process 2. Service time of the electrolytic cell 3. Service time of the membrane 4. Membrane leakage condition 5. pH of the brine fed into the cell 6. Dechlorination tower process 7. Structure of the dechlorination tower 8. Structure of the packing 9. pH at the outlet of the dechlorination tower 10. Free chlorine at the outlet of the dechlorination tower
