What do you do with your RODI waste water?

[Blue Spot Octopus]

I used it to water my tree in the backyard. Zero waste

 

[Forsaken77]

If I had a way to heat and pressurize it, the waste water could probably fulfill any watering needs I have, including showers. Mine feeds right into the drain by the washing machine, so I never see how much, but I know by the product water that I could've supplied water to a village in Africa for a year by now.

I currently make my RODI water in my master bath. I accidentally closed the plug while making water. It wasn't closed for long. But I was shocked by how much waste water was in the tub. I hate that I'm wasting so much water. I know that I can get a more efficient RODI machine. I'm looking at putting in a pool next fall. I'm considering sending the waster water from the RODI machine to it. So that leads me to my question.

Has anyone found a use for the RODI waster water and if so, what is it?

Send it out to the lawn.

i run the waste line into the washing machine before laundry day. good use for the first part of the cycle. hardest part was convincing the wife that i was not washing the clothes in "fish water" per se.

I did this for 15 years.

I return it to the earth.
I dont have a lawn or vegetation to water.
But i let it run out to the side yard.
Beats just sending it to the sewer plant, if I had one of those.

We are in an apartment, no yard, no garden, I have no use for the waste water so it goes down the drain, eventually ending up in the ocean.

 

[ppatches24]

We use it to water our garden. I’ve also used it for freshwater tanks in the past

Ive heard and read its terrible for plants. Is this not true?

The quality of your concentrate (mis-named "waste water" in this hobby for some reason) depends entirely upon.... the quality of your feedwater. Whatever contaminants are in your feedwater will be in your concentrate, minus x percent of the H2O - the contaminants are concentrated in the concentrate... hence the name.

My house plants love the waste water (from my well, not pretreated city water) ... can’t stop them from growing!

I am always wishing I ran my waste water out to my yard.

@fishguy242

I am glad you asked this question.
I always answer the question of, is this OK for my pet as no way?

I have no idea where humans (In General) have gotten the notion that feeding something to animals, we as humans will not eat or drink is OK.

Animals do not know that something is not good for them, they have no knowledge of such things like salmonella, mold, bacteria, etc. so they will eat it. They don't have some kind of instinctual means of detecting if something is poisonous, or bad for their health.

Most of us including myself have no idea if our animal is not feeling well. They can't talk and say hey Dad I am sick. We may notice they are not sleeping, or sleeping way to much, low energy, but normally, not until the symptoms become extremely obvious.

It has been believed that somehow an animal wont consume something because of there keen smell or some other super power DNA, or some miracle transcendental levitating mental telepathy.
Or that because they will consume there own feces, somehow they are immune to everything on the planet.

This is not logical thinking on our part.

Now I am not one of the germaphob's on the planet that tosses out food on or before the expiration date. Leftover combo pizza has been on the counter for two three days, no problem, I will eat that all day long. If I have a dozen eggs that are six months past the date guess what, you bet I will cook them up and have breakfast.
Hell I have even found a loaf of bread a time or two in the pantry that has started to mold. I will find the remaining slices without mold and make toast or a sandwich.
But I wont give the moldy slices to my pets, if I won't eat it they don't get to eat it.

Sure. Your concentrate will have lower TDS than my tap water.

You know never checked it,but learned here today ,did load of laundry with! lol

 

[Buckeye Hydro]

Some RO water experts suggest not using a second membrane unless your raw water TDS is very low.

TDS of the feedwater is not really the issue. "Total Hardness" is the problem. Likelihood to scale can be measured with LSI (Langelier Saturation Index).

 

[fishguy242]

would that be freshwater gh?

 

[Buckeye Hydro]

If you give me that number I can convert it.

 

[homer1475]

Down the drain. Same place all the waste water in my house goes.
