I want a small RO filter that will fit behind a small 6L DI canister so I can fill barrels from customer's outside taps.  It's got to be a 'fast fill' type, since I don't want to be hanging about.

Can anyone recommend one?

[Dave Willis]

Why not a twin DI system? would be much quicker but expensive on resin if tds is high. Can't imagine a small RO system could be made fast enough or cheap.

[Tom White]

Thanks, Dave, can you recommend a make so I can google?

[Dave Willis]

I was thinking maybe making your own. Didn't Ionics do a twin cannister system for a stupidly high price?

[Dave Willis]

Cheap aren't they?

I think I'll just stick with the DI!  Thanks, Dave.

I assume you mean I run tap water through both, using the old resin in the first; using that one as a kind of filter?  Then when the resin in the first DI is thoroughly exhausted, replace the resin and using the 'old' DI as the first one.

Hey, thanks!

whats your tds out of your tap tosh?mines 35-40 most of the time.i have a big 25L vessel for purifying at home and a small 2.7L DI vessel in the van for topping up on the job.

i take 250-300L of pure water with me every morning and ive not used more than that but that will probably change over time!!

i can always top up another 100 L while im out at work!
