Hi everyone,
Looking at breaking into the WFP market here in Australia.
My local TDS averages around 350-400 ppm, which is rather poor.
My thoughts where to go RODI, but i’m on a budget, which doesn’t exactly help.
I’ve bought a rather inexpensive 100gpd RO membrane off ebay, along with some 1micron sediment filters, and a couple of blue 10" x 2.5" filter housings.
I want the set up like this:
Tap —> Sediment Filter —> GAC Filter —> RO Membrane —> DI Tank (possibly 12.5L) —> Pole.
How does everyone think it’ll go? I’m concerned about the psi making it through to the (30ft) pole, and the RO doing a good enough job.
After the RO would 12.5L of resin be overkill?
Any thoughts or suggestions?
Thanks!
Sam
EDIT:
Ive crunched some numbers, again, and I think the 100gpd RO membrane wont work with how I want to use it, I think it would only produce 0.02lpm, and i’m pretty sure you need at least 2lpm to make it actually come out the end of the pole at a decent enough volume…
Ive found a rather bigger RO membrane, a 1500gpd 40" one… but no housing in sight…
How well would two 200gpd RO filters, plus my 100gpd one, (total of 500gpd/1900lpd) work on an on-site system?
1900lpd, works out to about 80lph, then 1.3lpm…is that sufficient?
Would I have to hook up the three RO filters inline, or adjacent?
If you’re all about DIY DI, here’s what supplies many of the RO systems: here
You could reverse engineer a 5 stage system. But regardless, you’re either going to have to put an inline pump (before the filters) or combine that with a holding tank for your water and transport/fill up at customers’ home and work it out from there.
Or you could save a whole bunch of money - spend $1000 to fly to a low TDS area and start life all over from scratch!
haha yeah no joke, but its otherwise quite nice where i live!
was there meant to be a link in your post? has it been removed maybe??
and I cant really cart my own pure water around, i’m just driving a small Subaru Impreza, and its been reaaaaally lowered, so I dont think i’ld survive till the end of my street with a couple of hundred liters in the back haha
Your best option is to find a 100 gal tank online. Mount it in your truck or van. Fill it up overnight with your 100 gal per day RO and a booster pump. Then use a pump box and hose reel to reach wfp. We carry everything you need. You can email me any questions you have at johnlee@windowcleaner.com
