DI storage help needed

Waterfed Poles
1

Hi Guys,
I’ve just finished setting up my RODI unit, (two prefilters, 4040 RO and a DI canister on a sack-truck/hand trolley) and its all working well, good flow and 000ppm (from 370ppm tap water)
But I just wanted to know hows best to transport it?
I’ve been using it to just fill up a couple of barrels on my trailer, but figured I might try using the pole directly from the unit.
Ive heard that you can mess up your resin by laying the tank/canister down or knocking it over, but im not sure to what degree.
I only run the unit when its upright, but to transport it anywhere I’ld have to lie it down in the car or on the trailer, would this be ok for the resin??

Also, another quick question: How much can I reasonably restrict the waste water flow on the RO? The incoming TDS is 370ppm, and I’ll need a flow rate of atleast 2/Lpm (0.6gpm i think)
The membrane is a Filmtec BW3HR LE-4040 (rated for Brackish Water and about 2400GPD)

Thanks

Hey Sam do you have a pic? That would help me answer your transport question…

That pic was taken before I had piped it all up, but you get the idea.
the top blue housing is the DI cartridge

Hey Sam,
I’ve got a system built on a hand truck similar to that. I lay it on it’s back in my minivan everyday. It’s been working just fine for the last 4 years. I get my RO membrane cleaned once a year and I change out my DI resin when the TDS is too high for spot-free windows, but that happens whether you lay it down or not. I also always run it standing up.

Hi, thanks for that.
Would it apply for a DI tank too?

Also, still want to know how much I can restrict the waste water flow of my 40" RO??

Horizontal transportation Is okay if Resin Is packed tight. Check with Membrane manufacture for the rejection ratio.

There is nothing wrong with transporting or using DI filters horizontally.

You can not use a DI tank horizontally however due to the internal design of the DI vessels.

Yes sam, my system is a 5-stage RO/DI RHG cart. It’s got both, a 40’’ RO membrane and 40" DI cartridge, so when I lay it down, the whole thing lays down for transport. You should have 1-1 ratio of waste water to product water for best results as far as I know.

If you use the cartridge type of di it does not matter. Many of the rental tanks have a tube down the middle so laying then on side can mess that up.
