Title: DI before tank or after ?
Post by: wpclean on May 14, 2012, 04:50:12 pm
I am getting a system fitted, and am thinking of not bothering with DI vessels in the van, and just filtering the water straight into the tank.  Does anyone else do this, just wondered if is was practical ?

Thanks.

I DI (O DO) after

If you ask why I would reply that this is the way I set up and it works for me. Opinions without rationale that's my bag.

I sometimes do both. Though I don't use an ro anymore.

why not just filter the water you make then pump pure in the van no need for di then, saves the weight

Surely that only works if you have somewhere to store a big tank; I don't have a garage or shed or anywhere else to put a large tank so I have two DI 's in the van.

Thanks for the replies, just to clarify I use DI only to filter the water as I have low tds water.

So you would buy a holding tank, provide the space for it, insulate it in winter, provide transfer hose & a pump, make the water then transfer it JUST to save the weight of 2 x 11ltr DI vessels on your van?


To the OP- have your vessels on the van, I recommend 2 x 11 ltr ones. There are no downsides, only benefits with this method. ;)

No I already have them, but I did also know you would post, your too predicable  ;D
benifits if you live in a soft water area I agree but as I don't tds is nearing 500 out of the tap so to do what you do would be madness imo and extra things that dont need to be there, hence my post  :-*

So who are you advising?

The OP states he has soft/low TDS water. I assume he's asking for advice on HIS circumstances & not yours- what ya think? ???

you asked on my tank , the answer would be NO it is pointless I dont insultate my tanks in winter they are in a unit made to produce water I pump pure into my vans  ;) for very low tds water I guess your right, even though I still would not do it unless it was under 30 tds but then I use quit a bit of water, Dave morris did this for a while then got an RO

Thanks.
personally I would put the di after the tank on the van, are you going to have a flow controller ?
reason being the slower the flow of water through the resin the longer the resin will last.

Your water is soft and so you will not be using an ro however mains pressure through the di will use up the resin far quicker than after the tank with a 12v pump and flow controller.

If one bag of resin only lasts 4 weeks with 50ppm then you're either purifying enough water for 5 full time vans or your doing something wrong!!

400ltrs a day & 3 to 4 bags maximum per year here with ppm of 90.

if your ro is giving out 50ppm then there is something wrong imo
