Methods for treating softened water in boilers
Thread Content
Our company currently has two ion exchangers for softening water. They worked fine at first; it took about four to five days for the water to need to be replaced once. Now however, it only takes two days. I’m not sure whether the resin inside needs to be cleaned or replaced, or if there is some other issue. I don’t know much about this, so I was wondering if anyone here could help me out?
Check whether there are any fluctuations in the pH level of the chemicals used for regeneration, the turbidity of the incoming water, and whether there are significant changes in the efficiency of the filters
Is it resin poisoning? First of all, what kind of ion exchanger are you using??
“Our company’s current water softening equipment consists of two ion exchangers. Is it a demineralized water system or a soft water system? Demineralized water is produced by anion and cation resins; the soft water system consists only of the first part, namely the “cation bed” (cation exchanger). “Does “replace the water once” refer to the water production cycle? The original poster could please provide details such as the inlet and outlet water parameters, water production volume, type of bed, and the regeneration method used, so that everyone can see if they can help further. Overall, the water production cycle (total amount of water produced per cycle) decreases significantly, and this is usually due to incomplete regeneration, large fluctuations in the quality of the feed water (suspended solids, conductivity of raw water), and contamination of the resin. For reference
A soft water system works by replacing cations such as calcium and magnesium in water, thereby softening it and preventing scaling in boilers; one cycle of water treatment involves the process from backwashing to refilling the water
If no errors occur during the regeneration process, then the resin is contaminated. Contamination can be caused by organic substances, high-valent metal ions, impure regenerants, oils, suspended particles, and other such factors
