Title: RO Unit Flow Rate
Post by: Smudger on August 24, 2009, 05:12:48 pm

Hi Guys,

I recently brought a 2nd hand WFP system that required an RO unit.

I plumped for a 400 GPD with 2 booster pumps.

i worked out that it should take around 4 hrs to fill a 250 ltr tank, BUT - it is taking over 6 hours.
i have checked with the supplier and all he could come up with is that it has a small DI unit - reducing the pipework from 3/8 to 1/4 " diameter.
but is sure its running at the correct rate as was tested and run before shipping.


Does this fill time sound good - or as i suspect its slow - at the moment my workload for WFP is reasonably light so 250 ltrs is just enough per day.

Have i made a boob with this ??

all help and advice gratefully received

Darran

Sounds low. My 300gpd with booster pump takes the same time for that amount of water. With a little di vessel.
Get a measuring jug and collect 1 minutes water from before and after the di vessel.
Is there any difference between the 2?

sorry I am a wally, no DSI on this system - would the width of hose make a difference?
