Is this going into a storage tank and then pumped into van / barrels. My psi is 23 and have a booster pump that boosts it to 100. I have a 40/40 though. I'm sure @Iron Giant has something similar to yours with a booster pump.
Thanks. At the moment I’m just going into 25l barrels but may look at a larger storage.
Can you recommend an upgrade, would that be say a 600gpd? Sorry not up on this subject.
Neither am I on the smaller R/O's as I've only ever had a 40/40, that's why I tagged IG in but by a previous post he might be asleep now. Fairly sure someone that uses a GPD R/O will pick this up soon.
Nope still awake not long got back from the allotment.
If you have 3 membrane housings you can just change the membranes to 150gpd. If you have a tap that you use to adjust the amount of water to waste then this will need a slight tweak.
You're only removing 82.5% of the impurities and it should really be between 96-98% so the TDS after R/O should be 11 or below. This could be the membrane needs replacing or your water pressure is to low.
Awesome, thanks for the advice guys. I’ve got a booster pump. It’s going through the RO at 85psi. It is a second hand Merlin RO unit, so maybe the membrane needs replacing. Will run it for a bit to see if it comes down first ??
I think I might buy a new R/O because I am dumb founded with mine I have changed practically everything on it over time since my nightmare 2 years ago and production should be on par with yours
No. Its time to get shot of the r/o. Sorry to be blunt. Not only does it have a high water consumption but its poor efficiency means you will spend more on resin than you have to. Eventually a new r/o will pay for itself on resin saving alone. At one time the r/o put 5 liters of water to waste to produce 1 liter of pure. This means the single Fiberdyne sediment/carbon block filter had a shorter service life which in turn effected the membranes (you have to replace 2 membranes).
My 450gpd needed around 28 hours to fill a 1000 IBC tank with 50psi water pressure - no booster. That was in summer. In winter with colder water it was nearer 36 hours to achieve that.
Bruce, thank you!!, In years gone by I would have no issue in producing 300ltrs of pure in 6 hours in Summer without a booster pump and not too much longer even in cold weather maybe 8-9 hours, it's now taking the same time with a booster pump it's like there is a blockage or issue with my R/O but absolutely nothing is visibly wrong.
He is in his twilight years I am been gentle and accommodating for a chap in his 70's , if I offered you an 8 pack you would be on it like car bonnet even if you sank 12 cans you would go home sober or drink more and phone your son ??
