Hi All
I want to get a small DI Vessel as a polishing unit say 5 ltrs any idea where I should look? as I refuse to pay £36 postage required from one supplier I found
It needs to be small to fit in my trailer
Steve
Do you think i am tight ?
-
Hi mate.I know you want a small one but i have a 25ltr you can have for £50.oo if you have no luck.Im just up the road in Banbury

Thanks Gaz
Looks like I have to pay the £36 postage it was them I was refering to

Bare with me then,i`ll find you another one,Gaz

I have the RO man one at the moment, but it only has the small bore pipe I was
hoping to fined one with hoselock connectors

you can undo the threaded small bore entry and exit and change them for hoselock

How quickly would this method take to fill a 25 litre container?
I take it you use one of these to fill up 'on site'?

Hi Tosh no in my van i have two 25ltrt di vessels to polish the water after its been through ro.With the bigger vessels ie 25ltr the resin should only need changing every 18-24 months as its a bigger vessel
-
If I opted for a bigger vessel could I use it on it's side or dose it have to be upright?

Thanks, but what advantage does that give you over putting your RO water through a DI where your static tank is?
I'm not being 'smart' here, I genuinely don't understand.
I'm only small cheese and work from my car using a back pack and I'm limited by my water carrying capacity. I intend to get a trailer shortly but in the meantime, is it possible to produce 000 TDS water from an outside tap - quickly - through a DI?
I'm sure it is (I think), but haven't a clue what DI vessel to get.

Tosh
The idea of a DI vessel in my trailer is to polish off the RO water after
transfer to the trailer, but befor it goes up the pole!today for example
my tds today was .002pmm at the pole. putting it through a DI unit would
remove any small amount of impurities left over from water transfer or any
other minor contamination (belt and braces)

Thanks Steve,
So it's a 'safety' precaution, just in case your water gets contaminated before it goes up the pole.
I learn something new every day.

BUT
if you put pure water into a container / tank, the water will stay pure, well it allways has for me, and my barrels have bits of leaves and berries in the bottom of them
BUT its still 000 tds
isnt it a bit overkill ?? ?? ?? ??

Don't knock it, if it works, it works.
But can you get a DI to refill up on site? Something smallish and would it take long to get a 100 litres out of it?

Mat
I am not sure but looking at pro built systems they all seem to
have DI polishing units. now I thought the idea was thet even if the reading from the Ro went up a few TDS even over a few days
you could still go to work knowing your TDS was 000ppm
as it woulg be going through the DI unit on site
is this not right?

not knocking it, i just think its overkill and not needed
yes, you could use it to knock-out 100 L of water from a tap, the only downside is, the resin would be depleted rather quickly

in theory YES, but most pro built systems have a RO in the van aswell, as its all self-contained, so i guess the DI is part of that
Ive been chatting to a local guy who has a Ionics system, that has a DI bottle in the van, he says incase he runs out on site and needs some pure water
Im only speaking from personal useage, i have 2 Barrels sat in my front foot-well, that have bits of leaves etc in the bottom, they have been unused for about 2 weeks, they will stil be 000 TDS
000 TDS doesnt just start to rise and become impure, well not to the extent we need to worry about
-
another thing
When you see these trolley system, DIY or pro made, they dont have any resin containers built on them
Im not trying to convince you not to buy a DI container, just trying to save you a few quid if its not needed

Mat
This has been a usfull debate and I thank you all for your input,
it's through this forum we all learn
But just to confirm you use your water from the RO into barrels
and no DI Correct?
-
Tosh if you had a di 25ltr on the in you come form an outside tap and out into you static tank yes you could make pure water in seconds but it would cost a bit in resin
-
There are two ways to make "pure water"
If you water supply has a low TDI and after going through a reverse osmosis system you could have 000 water even if it comes through 000-12max you could use this every time WITHOUT any Di vessels.
If you do not have a reverse osmosis system you could make 000 water through Di as well.
To do it through di you would need one 25ltr vessel for filling into your tank or water carriers ,bottles etc and then another 25 di vessel from your water containers through the pole.
The reason for the di filler is because you wouldnt be able to remove as much minerals this way than a reverse osmosis.
Also using resin only depending on how much water you use then the cost varies.
When i first started i had one di filler and was running two di for two poles.
We got up to using 700ltr of water each day but three vessels needing filling with new resin every 2-3 weeks costing £300.oo plus so reverse osmosis is the more economically way to do it.

No, i just have a small DI after the RO
so the water goes into my rain water butt at 000 TDS then i draw it off into 25 L barrels

Hi,
Have a look at our website at http://www.andwat.co.uk/acatalog/MISCELLANEOUS.html to see the three sizes of demin columns that we do - 17", 22" & 35" high. They MUST be used upright, to prevent channeling. Our carriage charges are way below what you mentioned.
Hope this helps, Andrew
