Hi all sorry for another stupid question.  With these big 3k systems you can bye and have mounted in you're van do you just fill then straght from your garden hose and the systems purify's as you work ? Or do you still need to put pure water in then to have them work best . Once again in sorry for the stupid question as I'm sure I know the answer to this one but just want to double check with you pros . Thanks

[Don Kee]

It probably wouldn't produce pure fast enough whilst you were working if you tried to produce 'on the job'

Van mounted RO's are basically for those that dont want a static system (i.e a storage tank) but the theory is still the same

Turn RO on and fill up tank, one system fills the van, the other fills a storage tank/IBC...RO will still take the same amount of time to fill up with pure

Looking at another thread, you live in a flat. Anyone live near-ish to you that you could use their water supply? Maybe parents/other family wouldn't mind you putting an IBC in their garage/garden until you can find a more 'long term' solution..?

With a van mount and a booster pump a friend can fill his 500ltr tank from a tap in 30 mins.
So if your able to park close to your flat and run a hose from window down to your van, on that basis it may not be an inconvienience.
Or a non van mounted RO (tho depending which one you get. For instance a 450gpd is smaller and slower than the bigger RO systems you can get) you fill into storage units and can be a little slower. So are you privy to any land at your flats under a window. So same idea as above but smaller tubing you could tack to the wall and run down to a couple of slimline water butts.

But if your tds isnt overly high you could run 2 DI vessels and quickly fill your tank from a friends access point??

So very simular points to Don Key, just because your in a flat it shouldnt limit your options.

i dont believe hes making that much in half an hour, is that through 3-4 40/40 membranes or something or DI. Thats about 16lt a min of pure never mind any waste.

sorry my bad,  i've just seen his van system 

[Dan marsh]

Well thers absalouty no chance for me as I live above a shops with no parking. But my buisnes partner has a house with drive and a small let's say shed running down the side off his house.  We have spoke about doing it from his place but he wouldn't have enough space to put a big tank in his shed as not big enough and these ro systems  look like they take a long time to fill up. But if we could find an ro system that would only take 30mins to to fill our van each morning then that would defantly be something we could look on to . How do i find these ro systems ? If only found these systems that you set up near you're sink . Think there about £100 . Think pure freedom do them .

I took it to be a 500ltr tank, maybe its a 350 instead.
But whichever size it is, he told me it takes about 30mins to fill.

For those thinking about making water that live with actual ground .....  think outside the box.... bury
your tanks, combine with rain harvesting .... there is more than one way to skin a cat.

Like others have said if you land space is limited.... find a place, warehouse,  storage unit, farm unit, friends place, other similar business operators...when your choices become limited, allow your mind to think 'unlimited'.

4040 RO membrane, much better than the 450gpd RO's (I've had both)

Faster and more efficient, you should get 100litres per hour minimum (not quite the 1000 l/h quoted above though so I'm interested to see what RO that is...)

In your situation I'd van mount a 4040 at your 'business partners' with an auto shut off valve.
Connect/plug in to outdoor tap when you get back and it should take around 5 hours to fill a 500 litre tank in your van (depending on flow rate and pressure) and then will automatically shut off...
Disconnect and lock up before beddy byes and jobs a good 'un.

When you get into a better position, you can take all the RO out and set up a static system in the future

Even at 350 thats still over 11lt a minute without any waste what R/O does he use then?

He has a purefreedom van mount system with a " powerful booster" pump (his words)

Why does this seem impossible to some as i dont understand. Another lad I know also has a van mount with booster pump though not sure his tank size but again it doesnt take him long to fill the tank either.

Don Kee has given you your best option, you're going to have to be realistic about this, you're not going to get a standard 40/40 R/O unit with just 1 membrane producing 350/500lt in half an hour, to get this sort of rate your going to need to have a system with probably around 3 40/40 membranes connected with a booster pump ..something like this https://www.grippatank.co.uk/grippapro-s3800-ro-pro-static-system-800-1600lph (you would be able to get it cheaper then this if you built it yourself). Why dont you see if you can buy water for the time being from someone local who may sell it, other then that find a lockup or something to rent out.

Not sure what  a powerful booster really means a membrane is rated at 80psi or 100psi so a booster doesn't need to be any more powerful than that with 1 membrane. Even with the 350 running at 50-50 waste to pure means there needs to be at least 23 lt a min coming out of the membrane. Fair play if he does but i find it hard to believe. 
Presuming he has something like this http://purefreedom.co.uk/product/2400-gpd-high-volume-reverse-osmosis-system-40-membrane-40-hf5-2/ they say it produces 10910lt per day (24 hours) so about 454lt an hour so about 227 per half hour and we all know the claims made by these suppliers are with perfect water temp etc etc and are never actually acheived.
The above is why i seem it not possible.

Wouldn't matter as domestic plumbing wouldn't be able to cope with that sort of output, it would need to be connected
directly to the water mains or some sort of commercial supply to achieve 350/500lts in half an hour.

Domestic plumbing wouldn't be able to take the output as half inch piping restricts the flow, for him to be getting your numbers
he would have to be bypassing the house plumbing and taking it directly from the mains which is illegal.

[SB Cleaning]

Why not just buy a ro/di van mount system and run a hose from your mates house..plug the hose in a external van port and lock the doors and leave it to fill overnight? Solenoid will turn the water off so i dont see a problem here

[Dan marsh]

That's perfect . So just leave the outside tap on let the water work throgh the ro system with a hose from the ro straght out to the van with an external attachment to the van mount systems. Sorry I'm not a diy kinda guy so there is a device that can tell when the systeam is full and can automatically stop it ?
