During the regeneration of a pure water mixed-bed resin system, if the injection of acid and alkali is interrupted for 4-5 hours, what impact will this have on the resin in the mixed bed? Also, I need advice on how to treat the regenerated water from mixed-bed systems
Interruptions in the application of acid and alkali have little impact on resin regeneration; however, it is advisable to continue applying some acid and alkali. There is no need to recalculate the amounts of acid and alkali – simply ensuring that the process continues for a longer period of time is sufficient. The most important aspect of mixed-bed regeneration is the regeneration of the resin at the interface between the anion and cation resins; the resin in other areas can generally be regenerated properly. Therefore, interruptions only lead to potential \"cross-contamination\" between the acid and alkali. By increasing the amount of acid and alkali applied, there are basically no problems.
