Does resin exhaust faster at higher flow rates?

[con95a]

Wondering if there's an optimum flow rate to pump water through a di vessel, or can you pump as fast as you want?

(For example, if I theoretically pumped 100 litres through at 20 litres per minute, would the resin exhaust faster than if I pumped the same 100 litres but at a slower rate of 2 litres per minute? So same amount of water, same ppm, just faster flow)

Yes, the resin wears faster at higher flow rates. Can't remember why it is so at the moment, but it's true.

This is up to a cerrtain point of course, it won't last indefinitely if you just let it trickle through.
