Mixed Bed Demineralizer Plant

Mixed Bed Demineralizer Plant The mixed-bed demineralizer is one of a high-quality water treatment plant’s most important (and expensive) element. Here are a few tips to keep in mind during the regeneration process:
The backwash should be extended
The cation and anion resin beads will be separated by the backwash of a mixed-bed demineralizer. A good separation is required to ensure that the correct beads are soaked in either caustic or acid. This is how a decent separation should appear. It’s worth noting that the anion beads are on top and the cation beads are at the bottom. Also, ensure the resin bed does not rise too high in the vessel, causing the backwash outlet to overflow.
Drain down the waste tank
Stop the regeneration and neutralize and drain the waste tank immediately once the backwash is completed. There will be no harm to the resin beads, and you will avoid having to cope with a sizeable waste-tank level later on in the regeneration. This technique is convenient if you’re performing a “double-regeneration” (where all chemical injection timings are practically twice) on a unit that’s completely depleted.
Increase the preheat wash downtime
The anion beads are prepared for the dilute caustic injection step during the preheating step of a mixed-bed demineralizer regeneration. The pollutants from water entering the unit during service will be flushed by soaking the anion beads in hot water. The hot water will also warm the caustic supply pipes, allowing the caustic to flow more freely throughout the regeneration. Because of these two factors, it’s advisable to leave the preheating step a little longer. Experimentation and your operational methods will determine how much time you need.The size of your hot water tank will determine how effective this tip is.
During the chemical injection, keep a keen watch
During the chemical injection phases of regeneration, a good operator will constantly check everything. Some process methods rejuvenate each resin separately, while others regenerate both simultaneously. Things will quickly become nasty if dilution water flows are not monitored during the preheating process and are incorrect. Keep an eye on chemical concentrations and deal with any problems as soon as possible.
Extend the chemical displacement step in the last phase
This is a personal preference, although it may assist with conductivity difficulties during the rinse-down process. If you have any hot water left over, run this procedure for as long as possible to eliminate any chemical residues left over from renewing the resin beads.
Neutralize the waste tank right after the air mix
Stop the regeneration process after the air mix and neutralize and empty the waste tank. The last rinse process will not cause headaches as a result of this.
Conclusion
Above all, the most crucial piece of advice is to understand your system entirely. Good luck with your mixed-bed demineralizer regenerations in the future.
