5 stage RODI & how can I produce more water faster?

[reefah]

Question, I have a 5 stage rodi system that currently gets about 50 PSI and 5 gallons for every 2 hours. Is there anything I can do to increase this a bit?

y;es get a booster pump to take your water pressure up... they sell a device called an ro buddy that is actually very good for this... or you can diy a pump, but the ro buddy is pretty much not more than the parts cost to build it yourself is why i highly recommend it

also whats your water temp, ideal for most brands of membranes i have come across is around 70 degrees .

I have an RO buddy and it works well tho I have never timed it. I have a float valves on both of my containers so
I just let them run, usually over night. If you go that route be sure and remove your flow restrictor.

Thank you for the tip! This is perfect!

How many GPD is your RO/DI?

The RO buddy is nice, but it does max out at only 100GPD.
if you system is larger than that, you are probably better off with the Aquatec 8800 or 8852 booster pump. That one is good up to 200 GPD.

if you do have a 55/100G GPD system currently, but think you might go up to a 150 GPD system eventually, the RO buddy pump won't be sufficient and would also need to be replaced.

You can get a 8852 kit, complete kit with all needed selonoids, switches, and even an extra pressure gauge for like $140 total so that is usually what I recommend. Google "SET88 booster" to find the whole kit for $138.

This is awesome. I might end up going with this!! thank you for your input!

I upgraded to a 1200gpd unit that growers use and added a booster pump to it and then run through anion and cation RODI resin. I can make 55g in like an hour
