RO/DI waste water recycling to DI resin

eshraghi · 07/12/2010, 12:09 AM

As in intro:

I have rather low TDS water from my tap at approx 28ppm. As such, I run a BFS chloramine special and have TDS 0 output.

My question:

Can I hookup a unit like this BFS-366:

to my output water and reduce the waste to near nothing until I exhaust the DI resin? Will this backpressure reduce the efficiency of my original RODI unit?

Or should I just pump the waste water into a waste bucket, and then use a seperate pump to pump through the DI resin?

Thanks so much,

Thomas

if you contact buckeye they will be able to set you up with all the stuff you would need to make a no waste system, IMO the cost of it isn't worth it though but we have cheap water here.

If you water your plants with the wast or use it to wash clothes, then it's not wast at all.

Is your waste 0 TDS or just the product water.

Most people who want to reduce their waste water actually run it through another membrane, then DI. If you run waste directly through DI only you will exhaust the expensive DI rather quickly.

To run a dual membrane system, you'll need a min water pressure 65 PSI. You will still have waste, but it will be about 1/2 from a single membrane system. Since many homes PSI shouldn't be much higher than 65 PSI for other plumbing reasons, some people will resort to a booster pump.

I just water my lawn with the waste.
