In a van mount is the water in the container tap water that get purified as it goes through the RO? If so, where does all the waste water go?
I've been told that it's better to have a static system and purify the water at home and just decant to Van.
Would most agree that static are better?
I'mthinking of getting a 40/40. Is this any good or recommended.
Thanks

Hi mate
First you need to find out how hard your tap water is, for this you need a tds meter or take a sample to a local wfp supplier or a local wfp'er to test. this will dtermine which kind of system will suite your needs best.

I've got one and it is 380 pps. I have a water softner as the water is very hard.

If you say where you are, Andrew, someone might be able to show you theirs

go for a 4040 ;)

I think that's going to be my best option rather than a cheaper RO man 300 which was what I was looking for. Any ideas where the best place to get a 4040?

are you going to fit all the stuff yourself?
I mean in van ect.

I have a couple 1000ltr ibc's at home in the garage, with a system with 4040's, then pump to van when pured. I think its better than having it in the van, just unnecessary weight, though you can fill the tank straight from the ro di. I keep them on blocks in the garage, and fill the tank in the morning.

I've spoken to Gaps water and they said it's easy to fit the 40/40 together, so I'll do that in the shed.
I will not have the RO in the fan just the tank pump etc with the pure water in. I want that fitted properly caged ply lined etc so will get that done professionaly. I'm not that DIY savvy.
Can you recommend any firms to do this fit out or any other advise re starting out?? Going live in May so just sorting things out now.

Why do you need 4040 on a static system?
-
Why do you need 4040 on a static system?
good question. Unless using more than 1000 litres per day.
-
I was told and read that in a hard water area output would be low with 300GPD. What would you recommend for a static system then?
I will have 500ltr in van and use 250 a day.
-
I'm not one to recommend - i have tds of around 380 and a 300gpd roman that gives me pure of tds 4. Buy a 4040 if you want i am just curious of the need for one that's all. :)
-
I've used the same 300gpd RO-man system for the last three years. Still the original membranes and still giving 4-5 ppm from 280 input. I can get up to 1200lt/day. Have just ordered a new 2000lt/day from RO-man as there are now 4 (soon to be 5) of us needing water every day but for a one man band you can't beat the 300 gpd.

why not have a 4040 if you have the money to :-\, I like things done quickly, I could of got a 300gpd but i didnt what it.
and in a year if you are using say 2000L a day you will have to get another RO.
No one can tell what the future holds, this is IMO thats all guys so please dont jump on my back for giving my opinion
-
yes and it depends on your tap pressure too, i have a twin 4040 system which makes 1000 litres in about 2 hours... this has an electric pump to produce that kind of water..
i also have a 300gpd pure freedom ro, which runs of my tap pressure, this is not that high and it will fill a 1000 ltr ibc in about 125 hours. So around 200 litres each day/ 24 hours i leave it on overnight. The waster is almost more than the production but i think its about 50% waster 50% pure water, i just have the waste runing around the garden watering the plants.
obviously its different where you live what water pressure you have, this is in a hard water area, and my tap tds is about 250 and goes down to 25 with the ro. Then 0 through the di. Its quite slow, but thats fine for me as this is at my other base right near my round so i can fill up from there and i dont need that much water from there.
but i would go for a single 4040, that will still make it allot quicker

twin 4040 now theres a thought, I am only getting 650l in about 4 hours maybe I should get another, then again I dont have a pump.

only 650 ltrs in 4 hours only? do you use more than that in 4 hours? whats your tap pressure like?
the only thing i dont like about the 4040s is the cost of new membranes, but regular flushing should keep them good.
its a kind of weird looking industrial electro crazy machine with a 24/7 pump & with two 4040 ro's on and di. Shown on here before. works well though! you dont really need something like this just two 4040's would be just as good or 1 on its own is still plently of water production

2000 litres a day? yeh after a couple of months you'll be using that much water with all that work you'll have, and billy whizz speed. Ian , the guys a newbie asking for advice ::)
Ian, you couldn't have used a 300gpd because you have a van mounted ro unit so you need 4040 because you have no holding tank and therefore need a fairly quick overnight fill directly to your van.
-

I know hes new, my advice would be to get a 4040. as I said in the first place.
if money is tight then a smaller 300gpd is fine.
Ian
p.s some people like the better than neded stuff, I am one of them
-
as Ian calls it 'the beast' i dont really need that industrial ro unit atall, but it will come in handy this time by next year hopefully il reach full capacity this year
i do some work in cambs too Ely area and all around there where abouts are you?
-
A newbie? right oh, lease the biggest most expensive van you can lay your hands on, buy the most expensive poles you can get, buy the dearest most elaborate ro unit you can buy then get some work. Good advice ??? ::)

I didnt say get a expensive van or the most expensive pole at all, I said get a 4040.
a 4040 is not the most expensive RO you can get but why get a cheap one as this is one of the main things to make the water.
-
Andew44 ask your questions to someone like Alex Gardiner or several other suppliers tell them the kind of work you have, how much you want to spend, they will then ask you a few simple questions like what is your tds? How much water pressure you have etc. Alex will even send you a tds meter and a pressure guage and advise you on what you really need for your kind of work and capacity. You don't need to produce thousands of litres of water for a small domestic round. No on uses a thousand litres a day on their own.

DJW do you have a problem with me ?
I have my opinion and you clearly have yours I'm cool with that. I would still get a 4040 and I dont use 1000L a day.
Ian
-
Nope, the only problem i have is people giving out poor advice and "willy waving"

at the last part.
DJW that is your opinion m8 and I respect your opinion, mine is get a 4040 if you can afford to, thats IMO.

i've been wfp'ing for 2 years now and i started with a 100 gpd and then upgraded it to 2 x 150 membranes = 300 gpd and i use 850 litres a day and it copes with it, why buy a 4040 when a 300 ro-man unit will do the job?
why buy an RO that you have to upgrade ?
if you have to upgrade again in 2 years let me know the cost and I bet a 4040 if you had got one in the first place would have been cheaper in the long run and saved alot of messing about.
I stick by what I say, and I dont mind taking flack for it.
Go for a 4040 :P
-
Forget having an RO in the van,unless you don`t have anywhere to make water at home.It looks good but in reality it aint practical.Go out to work come home fill from static for next day stick the darts on with your feet up.
-
i use a 300gpd ro with a booster pump. Cost me £265 all in at the time. Probably cheaper now. Tds in 480ppm out 5ppm. After di vessel 0.
It will produce over 1000 litre per 24 hours, but the booster pump is critical in achieving this.
No need in having a ro in your van unless you have work that requires you to fill up on site or you can't have a static system at home. No point driving around with water in your van when you don't need to. Especially with the price of diesel nowadays. Dunno what price a 4040 is but for most sole traders its like using a sledgehammer to crack a nut.
-
You mean you don`t need a 40x40 don`t you,i think your right.
-
Well whoever it is that started this thread, you can buy my 300gpd pure freedom RO from me if you want. Its only just over 1month old, allways flushed before use, with an inline tds meter, no longer needed, with a small DI vessel and resin and tubing. Cheaper from me, cost me 150 for ro, 25 for tds meter, 25 for di and resin
scwcs@aol.com
or you can get a 4040
-
You got that from Ebay didn`t you.
-
yes pure freedom on ebay - the industrial was from ebay too . Everybody loves ebay its like some sort of hysterical giant grey monster twisting your mind sucking away your irretreavable cash

That is not a 300gpd RO. It sounds like a cheap chinese knock off. It should produce 300GPD!!! which is (us gallons) 1140 ltrs in 24 hours NOT 125 hours!!! Total rubbish.

It can produce 300gpd in 24 hours , i didnt say it couldnt, its just where i live i have a low water pressure, thats why its slow for me. It all depends on pressure, so if you have a high pressure, or booster pump upto 125 psi then its obviously going to produce much more than what im getting.
Its not total rubbish, it was bought from Purefreedom, a respected company who obviously do not sell cheap chinese knockoffs.
this is where i bought it from if you want any other information go there

Nothing wrong with a 4040 if you may want to expand the business eventually. 300 gpd ought to be sufficient initially but they don't give good results in all situations. I was getting 450 litres a day from mine - and that was with a booster pump. There were odd occasions, when I was working hard and needed high flow rates for first cleans, that I was in danger of running out of water. Typically, you should get rather more than that though. A decent compromise between a 300 gpd and a 4040 would be a Merlin. I have one of those and it would give me a bitr over 1000 litres a day (without a booster pump) if I had the storage capacity. They are said to be wasteful of water though so may not be your best option if you are on a meter or in times of supply difficulties.
