After double-volume regeneration of the chlor-alkali chelating resin column, the quality of the secondary brine is not up to standard. Could anyone provide an analysis of this issue?

Quality of the secondary brine after double regeneration in the chelating resin column
1. Incomplete doubling regeneration； 2. Deviation in resin caking flow ； 3. Internal leakage in the corresponding valve ； 4. Quality of single-stage brine ； 5. Excessive load ；
Agree with the comment above! The possibility of incomplete double-volume regeneration is low; it’s very important to ensure that the operating cycle of the resin tower in question matches the production load! Of course, it’s possible to check for internal valve leakage and whether the temperature of the brine fed into the resin tower meets the required specifications.
This question is difficult to answer for many reasons; the original poster hasn’t provided enough information, so one has to look up and analyze things on their own. Wanhonghui1111 and aldd761 have covered everything very comprehensively.
Even after doubling the regeneration process, the quality of the brine remains unsatisfactory. It is recommended to analyze the quality of the brine first to determine whether a high SS content is the cause.
