Reproducing step:

In During the reproducing step, it is significant to manage the cation and anion resins at their proper volume. The resin interface will not occur at the proper place in the vessel if this is not completed, and a few resins will be exposed to the wrong reproducing solution. It is also important to realize which if the ion exchanger has been included along with radioactive materials; both the backwash and the reproducing solutions might be highly radioactive and must be treated as liquid radioactive waste.

The further step is the slow rinse step, display in figure, in that the flow of dilution water is continued, other than the caustic and acid supplies are cut off. In During this two-direction rinse, a last of the reproducing solutions are flushed out of the two beds and within the interface drain. Rinsing from two directions at equivalent flow rates remains the caustic solution from flowing down wiithin the cation resin and depleting it.

Within the vent and partial drain step, described in Figure, a drain valve is opened, and a few of the water is drained out of the vessel so in which there will be space for the air which is required to re-mix the resins. Within the air mix step, air is commonly supplied through a blower that forces air in by the line entering the bottom of the ion exchanger. A air mixes the resin beads and then leaves by the vent within the top of the vessel. While the resin is mixed, it is dropped within position through slowly draining the water out of the interface drain although the air mix continues.

In the last rinse step, displays in Figure, the air is turned off and the vessel is refilled along with water which is pumped in by the top. The resin is rinsed through running water by the vessel from top to bottom and out the drain, until a low conductivity reading denotes in which the ion exchanger is ready to return to service.
