If so, did the membrane fit sideways in the van?

I have a Nissan Vanette if it makes any difference.

Thinking of filling up at the customers as I go 'round.

Cheers

Doesn't it make a mess when it comes to changing the membrane tho'?  Or the resin?

[mark blundell]

I did fit one sideways on in a transit. probably the worst thing I done as then I had to heat the van in the winter. I ended up taking it out and mounting it on a trolley.

I don't do window cleaning any more so sold it all. i only put it all in the van because lack of storage at home not to fill up whilst going round. i found that i could not fill up at my mum and dads house because there water pressure wasn't good enough and you would probably find this with a lot of customers.

would it not be a better idea to mount all to a trolley and just run that of off the customers hose if you are looking to use there water?

just pull the trolley out the van and wheel that round instead of using 2 hoses 1 hose from your van to the pole and 1 from there tap to your van.

put a 12v booster pump on the trolley and run it that way straight to your pole.

Forget the 4040 as no good unless pressure is high just use a spare Di vessel instead. Ok may get thru resin but my 7 litre will give about 2000 litres before its useless tds around me 130

What about running a booster pump off an inverter in the van - to get the membrane under better pressure?

[mark blundell]

inverters are ok but would just drain your battery why not just use a 12v booster

12v will never power a pump for a 4040.

3rd one down that has a 12v booster pump

RODI-B is the third one down and I would understand that this unit has 1 Shurflo pump which is to power water to the pole. The next unit down RODI - E has a 230v or 110v pump as a booster.

its a 12v booster look at the plumbing the hose connector comes out from the D/I to go to the pole, also it states that it draws its own water  • Machine will self prime ( will draw water from a tank ) 3 Litre per minute

so if it draws its own water it doesn't require the water pressure from a tap therefore is a 12v booster.

Good God, I can't believe those prices.  £3000+ for a sack truck with some bits and bobs stuck on it?  I've seen it all.

Anyway, useful to see a booster pump in those setups - if you can get water AND electric at a customer's (with permission), you could be laughing.

Got to find a way to get more room in the garage.  The water saving's no big deal really, but could be useful.

yeah there not cheap wht would anyone pay these prices?

here's the one I built with 240v booster but only used it at home to fill the van up. cost me about £600 in total. it was ideal as in the winter I just used to take it indoors. i also had my DI on a small trolley so could also take that in.

Looks ok, but what didn't look ok was the tds stayed at 20 ppm.

Was there a booster pump on that trolley?  I saw a battery, I think.

Hi Mark
I was always facinated with your 4040 r/o you built on the trolley and how much pure you were producing. I saw this video a long while back. The amount of pure coming out was amasing. You didn't show the amount of water to waste as well but I still can't see how a 12v pump will supply the amount of water a 4040 needs in full song. 

But you have superior knowledge of 4040's so I accept what you say.

What I see is the other units with 230v motors as boosters.

By the way, what pump booster pump did you use again on your trolley? I remember someone once asking that and I'm sure you did give the answer.

Thanks

Looks damned good work, and FAR cheaper than that other link.

[Blue Frog Systems]

i dont know why you would want to hook up an ro system at each house. for one its time consuming and two you would probably not produce enough water to keep you going.

im going from ro to di only soon as i will be moving into a smaller property without the option of being able to use an ro. you would be better off using a double di system. the extra jobs (say 2 @ £20) you could do each day would more than pay for your resin costs. also you wouldnt have to worry about freezing temps in the winter.

Hi I never could get the tds below 18 however I had this setup with or without booster

Hi Spruce,
yeah it really did produce pure quickly I was filling my 650ltr tank in about 2-3 hours

I don't think a 12v pump would work a well as a 240/110 but then it is only to get the water pressure up inside the r/o housing and they are 100 psi. i would be interested if anyone has one or has made one.

the pump i used was a stuart and turner cant remember the spec

cheers mark

Looking into it.
