The negative bed has been running for five years and now the cycle water production is low. Do you need to intuitively judge whether the resin needs to be replaced?

consult: Our two-tower and one-unit water treatment cathode bed has been running for five years and now the cycle water production is low. Do we need to intuitively judge whether the resin needs to be replaced? This post was last written by li * Edited by ch1968 on 2009-4-17 18:45 ]
Check whether the ion exchange resin has reached the scrap standard. Generally, it can be used for 8-12 years with good management. Check whether it is contaminated and needs forced regeneration or activation. This post was last written by li * Edited by ch1968 on 2009-4-17 18:43 ]
If it still doesn't work after forced regeneration or activation, you can consider changing the resin.
We have used salt and liquid caustic soda to resuscitate and backwash the resin, but the effect is not good. The resin is going to be sent to the manufacturer for composition analysis. This post was last written by li * Edited by ch1968 on 2009-4-18 15:46 ]
The resin should be replaced and added gradually on a regular basis. Each time a part is replaced, the resin in the lower part of the intersection column will be easily broken, and the broken resin will be discharged during the regeneration process.

Clean the resin, and then regenerate it deeply by extending the alkali feeding time and increasing the alkali feeding concentration. If it doesn't work, consider resuscitating the resin. If recovery fails, consider replacing it. How can you just replace something worth hundreds of thousands?
Check to see if it is iron poisoning. After iron poisoning, the resin will turn red, and the resin exchange equivalent will be reduced due to incomplete regeneration. You can consider soaking it in hydrochloric acid for a longer time.
What medicine is best for resuscitation? How much should the concentration be controlled?
1. Part of the resin may be broken due to improper previous operations.； 2. After 5 years of use, some parts will always be lost, and some should be replenished. ； 3. Complete regeneration, concentration 5~7%
Let's revive it and see how it goes. If it still doesn't work, we can only replace the resin......
