Wasterd RO/DI water

chase33 · 04/21/2007, 10:19 AM

Is there anything I can use the unfiltered waste lost from the creation of RO/DI water? I hate the fact that more than 4/5ths of the water goes down the drain. can I use it for plants or anything?

plants, cloths washing, drinking etc

You can use it for anything, it's still just H2O

By the time you get to the wastewater point you have ran it through probably 3 filters, 2 to reduce sediment and one to remove chlorine and other contaminants. It is waste water to the fact that it isn't what you want to use in your tank but it is cleaner than your tap water.

So get some of the empty 5 gallon jugs at walmart and a small water cooler, then you can have better water for your household and great water for your tank.

I use my 'waste water' for my other freshwater tanks BTW.

I added a second RO membrane and a booster pump to give me about 80psi at the inlet. Doing this has reduced my waste to about a 1:1 ratio! Take a look at thefilterguys for the specifics.

I'm glad I asked the question because until now it has been going down the drain. I have the Kent Marine Maxxima HI-S and in the directions they do not reccommend it for drinking becase of the lack of minerals and possible odd taste. As far as taste, I can be the judge of that. They do sell a add on kit for drinking water. I'll research that further along with the booster pump. At least no more waste down the drain.

Thanks

Why is there wastewater if I may ask?

That is a long running myth applicable only if you were drinking WAY more water than the human body could ever absorb.

This is true of DI water but RO water tastes great. You would use an RO by-pass kit for this. It basically allows you to drain off water after the RO membrane but before the DI unit.

As far as saving "waste" water, I forgot to mention earlier, I use the rain barrels with a hose adapter at the bottom to water plants and such. Just another idea.

It's rejection from the RO membrane - particles larger than water and water itself. Water is forced through the membrane - more than can pass through it. Something like a 4:1 waste to product ratio.
