Resin column regeneration time

During stable production or when the production load is low, many people consider extending the operating time of the resin tower from 48 hours to 60 hours or even 96 hours. Experienced colleagues, please share the advantages and disadvantages of doing so. ， ， -
This is done solely for the sake of economic operations. I believe that whether it is possible to extend the operating time of the resin tower depends on the parameters of the brine; as long as those parameters remain within acceptable limits, it should be possible to extend the operation time.
You can refer to the discussions at the following link: http://bbs.hcbbs.com/thread-574190-1-1.html
It depends on what resin is used, as well as the load on the tower. For the three-tower process, regeneration takes place every 24 hours; in other words, a switch is made every 12 hours, from the front tower to the back tower to the regeneration stage

A simple calculation shows that the cycle time = K/flow rate; generally, when the amount of resin used remains constant, K is a fixed value. Reducing the flow rate can extend the cycle time, as acid, alkali, and water also represent costs.
Reply to 5# pzhhuagong: Friend above, what does “K” in the formula you mentioned refer to? Some resin specifications list the \"exchange ratio: 30 times\" – do you know what that means?
Here, it is regenerated every 24 hours
