Mixed bed resin for uranium in well water

[Sri Dasa]

All: I have uranium level of 33 ug/l. In order to address this problem, I am looking at Anion resin exchanger. As I already have a water softener in place, I am being advised to replace the existing water softener with a mixed bed resin which will deal with both hardness and uranium. What do you guys think? Any downside of doing mixed bed exchanger?

A lot of variables there. We rarely mix uranium reduction resin with softening for a multitude of reasons but in general, it will work. It is much better to keep the beds separated.

Uranium reduction resin is fairly expensive and should be fed with soft water. When the beds are mixed the Anion resin sees the water first so no hardness protection occurs. This can lead to anion resin failure and the uranium simply passing through unnoticed. Two systems, one for hardness and one for Uranium or a specialized hybrid system that works similar to the mixed bed but separates the medias into individual tanks is preferred.

These are just a couple of the many different designs that are available.
