RODI speed

hi gmann,

My RO dealer suggested a use of a booster pump to extend the life of the membrane. A cheaper alternative is a permeate pump that you can get from water supply stores.

"Permeate Pump is a non-electrical device which is powered only by the hydraulic energy of brine water. The Permeate Pump forces product water into the storage tank, reducing membrane back pressure while maximizing available feed pressure. This pump drastically improves the efficiency of Reverse Osmosis systems and can reduce waste water up to 80%."

More info about your unit, 75 gpd membrane? 50? 100? How many stages, sediment filters? Do you have any idea what your source water pressure is?

I get a steady flow out of my 75 gpd system with incoming water pressure of just over 100 psi. More than just a drip. Also do water changes of 20 to 23 gallons. Takes about 5 hours or so to fill my mixing container.

Before you run out & buy booster/permeate pumps, confirm your water pressure. A pressure gauge is a very useful component to have on any RO system (I have 2). Once you've checked the pressure, see if there's a pressure regulating valve somewhere in your house plumbing, should be not too far downstream of your main water shut off valve. Most PRVs are adjustable & you may be able to crank up the pressure. Ensure all your plumbing is in good shape before you get too carried away.

Yea get a booster
