RO waste water what do you do with it?

I use my rejection water for everything. I collect it in a 32 gallon brute bin and then use for flushing my toliets, doing my dishes, doing laundry everything. The way I look at it as free RO water for water I would have used anyway.

Anyone as nuts as I am?
 
No. Your nutzzzzzz. Mine goes right down the drain. Too much work. Flushing toilets. Come on!

Not that I can't. Too much work to take a **** and have to go get my bucket to flush. You must live in California.

In all serious if you let it go down the drain think of the waste.

Take care of mother earth.

Nope Wisconsin.

I put the waste water drain right in my washing machine. When filled I do a load of laundry. 60 gallons for wash and rinse that would have gone down the drain. See my point? Agreed the toliet thing is extreme but just saying.

The waste water is not RO water. Its waste water that have high contaminates and heavy metals. Careful this water is not for human consumption.
Even taking this water to yard I stopped doing cause grass did not look good after couple of months living on the produced waste water...

Using it for toilet flushing puts you a bit into the "nuts" column in my book..
I use plastic straws and don't think the climate is going to be destroyed in 10 years :0
 
To ohashimz comment.

How can there be more then was originaly there? I don't drink it.

Also I have a well. Coming in on my meter is .52 and going out is 0.

Flushing the toliet yea I get it. Again just saying.

No harm in doing your laundry in that case.

Its more of the contaminate per gallon ratio. Not that you will have more contaminate than the input line..
The waste output contaminate per gallon ratio will be higher than the input line contaminate per gallon ratio.. which means the contaminates more dilution on the input than what it would be on the waste line.

That's how the rodi filter work.
It seprate contaminats from the water and give u 2 outputs: one pure water, one water with contaminates...

The evidence is easy: what's the tds of your rodi output, and what's the tds of the waste?

With a 4:1 waste ratio, the output will be about 25% higher in some ions than the input. On the other hand, it'll have fewer precipitates, and the activated carbon will remove some things. For low-TDS input water, the waste water probably is fine for a wide variety of uses.

Complete PIA but you asked. I had switch my connections around

.56 on input. Waste water out .48. RODI out 0

If you don't believe me I will post pictures of my meter.

Ha ha, no, of courses believe you. Maybe am complicating things.
I just thought the. Waste water is heavy water and should not be used for drinking. I remember reading something about that on a consumer report page regarding homes RO units but again maybe I am mistaken..
I stand correct:))

Works great on my wife's flowers with chloramines removed which is not the greatest for plants/algae. I just added 50' to the drain line and drag it around to her flower pots and beds.
 
Me.. i wash my pets with it.. do you think its ok? LoL. Also i wash my toilets too

My house plants grow much better with the waste water... been using it for ~20 years!
 
If the chloramine is broken down into ammonia, a bit of it would be fine as a plant fertilizer, at least for many situations. Higher concentrations might be an issue, though.
 
Higher efficiency dual membranes, a permeate pump and keeping the membranes flushed on a regular basis can get you to a 1:1 product to waste water ratio...

Less waste water is even better for the environment!
 
Excellent.

My point was even though I may be a bit extreme is why let all that water go down the drain. I look at it as water I would have used anyway so free RO water.

I didn't realize until I started saving my rejection water just how much RO water I could make out of water I had to use anyway. Also I realized how much water I go through on an average day. One load of laundry is like 60 gallons of water. So I just put my rejection line in the washer, make RO water drain the rejection into the washer and then do a load of laundry.

My point is we take great care of our water filled boxes, so we should take care of the resources that enable us to care of those boxes.

In California they charge us to look at water. If we are in a drought that year then thinking about water can cost a pretty penny.
My point is...... they are going to charge me regardless of what I do with it so I take great satisfaction on watching it run down my driveway into the gutter and down the street :)
FYI....... that's a joke!!!! I actually have my waste line run to my fountain to replace evaporated water. Might not be as good as watering plants but at least it's a second use.
