Making RO water

[PNWReefer17]

Just looking for a little feedback here. What's your average time to filter 5 gallons of water? Here's what I just did.

TDS in: 345-350ppm
TDS out: 0 ppm
62-72 psi
Time to produce 5 gallons: 1 hr 25 minutes.

Is this average/above average/below average?

I’ll time it tomorrow. Never have seems like I can make five gallons what seems to be fairly quickly when needed. How many gpd system do you have?

 

[AdamNC]

Summer time when it’s warm about 1 1/2 hours. Now that it’s cold about 2 - 2 1/2 hours.
100 GPD system.

I picked it up second hand and never got a manual for it so I had to poke around the internets a little. It's a Triton D100 4 stage system. The book I found online says 100 GPD and 4 GPH so I guess it's doing pretty well as far as time is concerned. Just kind of curious what other folks get out of theirs. Wife's gonna get mad that her kitchen sink is taken up every night to make water....HAHA!

My suggestion would be to make enough a week to do weekly water change and top off water and store it in buckets.

PIGGYBACK QUESTION : How long can the RO/DI water stand in a clean container before fouling?

 

[EriksOasis]

I keep my Rodi in a 30 gallon brute trash can for weeks at a time. As long as contamination doesn’t occur and the container has a lid you should be able to store forever.

I'm running a BRS 6-Stage Universal Plus with auto flush and booster pump. With 75 PSI water at 250 TDS it takes me 195 minutes (3 hrs & 15 min) to fill a 25 gallon container. So, I'm about 39 minutes per 5 gallons.

Little over an hour in the summer and 2 ish in the winter

It takes me between 45 minutes and an hour (longer in cold weather) for just shy of 5 gallons. I have a cheap-o "hose timer" from [Big Box Hardware Store] so it's easy to just set it and go to bed or go to work or whatever. It doesn't even require batteries.

We have a calculator (link on our homepage) where you can plug in your water temperature, your water pressure, and see how many gpd your membrane should make./

75 minutes in my case, we are pretty close to actually even.

 

[Buckeye Hydro]

If you have one of the most common membrane capacities, and IF you have factory spec pressure and temperature, and IF you don't have any unusual conditions that would affect production, here's what you should expect (plus or minus about 15%):
150 gpd = 6.3 gallons per hour
100 gpd = 4.2 gallons per hour
75 gpd = 3.1 gallons per hour
50 gpd = 2.1 gallons per hour

I make 5 gallons on the nose in exactly 1 hr. I usually run the system for about 10 min and use that water to rinse equipment before I start my 1hr timer

Pressure higher than factory spec -> faster production
Temperature higher than factory spec -> faster production

Sweet! Thanks for the feedback. Now to work on a little storage tank....
