Water quality in the drum
Thread Content
The PH of the drum is normal, but the conductivity has suddenly increased by 3 times; what is the reason for the increase in chlorides as well?
Chloride ions can cause rapid corrosion of stainless steel, and this issue should be given attention. 1. It may be caused by excessive chloride ions in the boiler feed water, or there may be an issue with the components of the chemicals added to the drum; analysis is recommended. 2. Increase the drainage from the drum; analyze and compare the chloride ions in this drainage with those in the boiler feedwater. If the conductivity and chloride ion levels in the drum drainage are high while they remain normal in the feedwater, it can be concluded that there is a leak in the drainage cooler, allowing circulating water to enter the drum drainage and thereby increasing the conductivity and chloride ion levels. There shouldn’t be any other reasons.
I’m not sure if you use the ion exchange method for desalination; it’s possible that the anion exchange resin has failed.
1. Increase wastewater discharge； 2. Adjust the dosage of chemicals based on the phosphate content in the wastewater.
