Ok so I have two 3 channel TDS meters on my 7 stage RO/DI unit....
1. Water coming into unit
2. Water after sediment and carbon filters
3. Water after RO membranes
4. Concentrate out of 1st membrane (feeding 2nd membrane)
5. Concentrate out of 2nd membrane
6. Water after DI resin.
So my TDS coming in is about 210 and the concentrate coming from the membranes is about 280. I've read that anything lower than 300 is still "good" water. Soooooooo......that being said I'm wondering if I can't reuse this water for....well anything. What is everyone's thoughts? Find a way to save and reuse this water or let it go down the drain? I'm thinking about getting some 55gal blue drums from work and filling them for garden water. But what else?
