R/O Alternative? - Kati Ani De-ionizers

Everytime you recharge you need to use somewhere close to 100 litres to rinse the stuff. I'm guessing you could burn the resin out pretty fast too. Might be a great setup for people with really low TDS to begin with but then again... those folks have it made with ro/di setups already lol.

You also need a fair amount of acid, and ideally, a large box of baking soda to neutralize it before you dump it. And it's a disgusting slimy mess. I'd never do it again. I used to collect those API resins and recharge them, but not worth it.

Basically we are talking about the DI part of the RO/DI are we not?
