Waste water?

[Hanco13]

I'm going to start collecting rainwater to purify. I just wondered, instead of letting the waste water that my RO system spits out trickle down the drain, it can be captured and then reused to purify again? I've never actually tested the purity of the 'waste' water which is ejected from my RO system, but it seems such a waste to just let it p*** down the drain. Have any of you fine gentlemen any advice when it comes to cutting costs when purifying? Thanks in advance fellas.

The waste water tds would be higher than your mains tap so it would need going through a ro again really as it'll kill any resin

 

[peter rogers]

yes i was thinking the same as but could you not loop the waste back into the incomong water ???? so it wud go

water tap> sediment>carbon>4040ro>pure water into tank

>waste water goes back to the start ie just before the sediment filter or would this cause to much pressure opr what ????

Maybe direct the waste into your bathtub and have a bath instead of a shower more often.

If you are producing a large amount of pure water per day the you will need a very large bathtub methinks for all the waste water. /emoticons/biggrin.png

I live in quite a hard water area so trying to put back through 400 plus ppm waste water back through an ro/di system would be an utter waste of time and money if you ask me. Not to mention the added running costs in doing so. Even trying to store the waste water to use on a garden etc you would soon end up have more storage tanks than actual garden to water. Unless you happen to own a farm or something then guess you will be not that bothered cleaning windows for a living.

I've already tried putting collected rain water through a ro/di system and it don't work using a submersible pump as the system needs good pressure to work. Therefore I'm curious to know how you would do this?

booster pump

It seems to me to somewhat defets the object of trying to be green if you have to start using electric to make pure water from rain water. Surely decent size booster pumps are not cheap to buy or run for long periods of time?

I only wash on special occasions, Birthdays, Xmas, etc etc, so no problems there lol.

Exactly the way you mentioned there Smurf. I've got two 650 litre tanks that I've acquired, just sitting there in the garden. I was thinking of collecting the rainwater in one, then using a submersible pump to chuck it through the RO filters, then use the other tank to store the resulting purified. Is this idea a non starter in your opinion Smurf-man?

Not fussed about being green mate, just thinking of knocking a few quid off my water bill tbh.

Save it and put it on none paying customers windows /emoticons/tongue.png

My rainwater I collect in a waterbutt & just connect a hose to it & join in to my di & let it trickle into my 2 backpacks or 2 25 litres butts. Rainwaters only about 11ppm so why need ro or pump. Just trickle it through a di. I did this yesterday & worked fine. It's only gotta trickle through unless yer all of a rush??

I get through quite a bit of water Posh and 'Er Indoors' has been on about cutting costs this year. Therefore Im just thinking about harnessing as much rainwater as I can for work. I figure if I collect as much as I can and then pump it through my filters, that way it's only costing me the electric to run the pump and it shouldn't take any more time than it does now to get a full tank.

 

[Posh]

That's right but if you had the time you could just run the hose from your but into a di & then in your tank. Remember rain water is only about 11ppm. If your tanks in yer van fill 25 litre cans up & then put it into yer tank. Obviously it take time but costs nothing.

were u live hanco like semi house or wat as u cud use next door neigbours water waste to

 

[SolarPanelCleaning]

Was thinking of irrigating a huge row of tomatoes with waste water. Just gotta find a way of reducing and splitting the pipe to send to different plants. I need to get out more.

 

[peter rogers]

u can get simple irragation tube and pipes feed of it

then u conect the waste to that

 

[SolarPanelCleaning]

Gotta be done then! Used hydroponics before but not played with soil much.

Would it be greenhouse kit type thing from garden centre?

Oooooh

The tds of your rainwater will depend what kind of roof you re collecting it from. At my house, with old tiles on the roof, it's about 45ppm whereas another place I collect it from is only 10-15ppm.
