Why Should I Add a Permeate Pump to My Reverse Osmosis System?


Benefits of Reverse Osmosis RO Permeate Pump

A typical reverse osmosis system utilizes an automatic shut-off valve (ASO) that stops the RO system from producing water when the holding tank reaches 50%-67% of the incoming water pressure. As the holding tank gets close to being full, the quality of the water produced by the system begins to diminish, as well as sending more water down the drain due to the increasing back pressure from the holding tank.

When a permeate pump is installed, the RO membrane is isolated from this back pressure and allows the RO membrane to operate with up to 85% of the incoming water pressure, even when the holding tank is nearly full. This dramatically improves the efficiency of the membrane and overall quality of your water, as well as increasing the pressure and related volume of stored water in the holding tank.


Greater Production From Your Reverse Osmosis Membrane

As a general rule, each person in a household uses about 2 gallons per day. In order to keep up with demand, reverse osmosis drinking water systems have been equipped with 35 or 50 gpd membranes with up to five stages of filtration. In actuality, a 36 gpd RO membrane produces only 15 gallons per day. With a permeate pump, production of the 36 gpd membrane will be close to, or at 36 gallons per day.


How a Reverse Osmosis Permeate Pump Works

Permeate Pumps for a reverse osmosis system are simple, yet revolutionary devices that use the energy of the water going to the drain as leverage to push the purified water into the holding tank. "Permeate" is a technical term for the purified water that is produced through the reverse osmosis membrane. The water that is sent down the drain after rinsing the membrane is called the "Brine." This device does not require any electricity because the pump is using hydraulic energy that normally goes to the drain unused. By using a permeate pump, the pump isolates the tank from the membrane and lets the membrane perform as though it were in an atmospheric tank system.




Saves Up to 80% of Your Pre-filters and Booster Pump Life

Because your permeate pump reduces the water going down the drain by up to 80%, your system is not exposed to all of that water and improve the life for your pre-filters and booster pump.
