WHAT RO FOR ME?
« on: November 25, 2007, 03:44:31 pm »
At the moment I purify onboard with 2 di vessels. My tds is only 34ppm. If I ever run out of water I simply fill my tank up a little because the tds around here is extremely low.

Becausee up to know I havent ever needed to even think about RO systems i dont have a clue about them!

But a big job I have requires me to leave my low tds area and because the job is large I will need to fill my water tank up. So what can I do? I suspect the reading of the water at this job will be between 100-200 so can I put it through an RO or should I just put it through my 2 di vessels and carry some extra resin? If I do need an RO what type would allow me to fill up a 500ltr tank quickly?

Thanks for your help, Luke

Hi Luke,
if you want an affordable and qucik filling RO then the Merlin is a good choice as long as there is a decent pressure  ;)

Most wfp sellers should sell the merlin usually around £280 and it`s just one RO  ;)

a 40 will fill it quickest,

is the job a one off? if it is just take more resin, an ro would be better in the long run if you are going to do this alot, my tds is over 470  >:(

Luke.

Keep life simple.

For one or two jobs even at 100 to 200 TDS just stick with resin. RO's are really very simple but to top up or fill tank quickly your gonna need a 40 inch unit and even then you will be amazed how much slower thay are to produce than DI only. You will want it mounted in your van as well so there's quite a lot of plumbing alterations to do. Also you wont be used to waste water which you get from any RO unit. The Merlin mentioned above is just about the worst one for producing waste. Up to 5 parts waste to one part pure :(

I am stuck with TDS of 400 plus all the time so I am used to RO's but if I could do without one I would. OK ur gonna save a little on resin use but overall it wont be worth it for you.

Producing waste is only a concern if you are on a meter  ;)

I am on a meter, I look at what I earn from it maybe it does cost alot, but nothing to what you earn from it.

OK I suppose ur right but Luke is talking about filling up from other's water supplies. Waste is an issue then. My comcern for the Young Jedi (Who has probably already ordered a Merin)  lol :)  is that he is going to be well shocked at how slowly RO's produce compared to DI only...even a 4040.

No Luke.. take mine and Ian's advice.. stick with DI only for this job. :)

At the moment is sounds like DI will be a good option but keep the suggestions coming, thanks, Luke

if you going to get an RO Luke go for a 40inch, you already have one of the best poles dont go second best an get a merlin for an RO

So even with a 40inch RO im not going to be able to produce water fast enough, maybe I'll just stick to DI. So let me get this clear, can DI on its own handle high tds water, I know it will go through resin quickly but will it actually get it down to 000ppm? Luke

Problem with the merlin is the amout of waste it produces.

With an inlet tds such as yours you probably don't even need DI if you use a good 40" RO Membrane.

I sell a 40" RO membrane that will produce 4 LPM with the help of the right 12V Pump.

yes it will but will cost more in resin as you say, if you have a tap at the place then an ro would cost less as you could fill as you go, just get there with a full tank and hook-up and get more water while you are working.

havre to add the 4.5 hours for 650l of water is not with a pump thats straight out of a tap
