Flow Rate with Variable Pressure and Temperature:

When sizing a system, particularly if system output is critical for you, you need to understand that the actual flow rate GPD(Gallons Per Day) of any reverse osmosis system depends on the input water pressure, temperature, and water conditions. The higher your input water pressure and temperature, the higher the pure water output. The industry standard*, which is the same as our standard, is set at 60 psi pressure and 77° F(25° C) temperature.

Output at 77 °F VS. Various Input Water Pressure
40 psi 120 GPD 160 GPD 175 GPD
50 psi 150 GPD 200 GPD 220 GPD
60 psi 180 GPD 240 GPD 270 GPD
70 psi 220 GPD 280 GPD 317 GPD
80 psi 250 GPD 320 GPD 360 GPD

*Please note that this standard is not necessarily followed by all vendors. We have seen other RO systems claiming 100 GPD at 100 psi —very unrealistic input water pressure! So do check on these facts before you make a buying decision.

More on water temperature: While the industry standard temperature is set at 77 °F, we know that not everyone has 77 °F input water. Below is a water temperature compensation chart for you to calculate the nominal GPD of your RO system at different temperatures.

INSTRUCTIONS: find your water temperature and its factor, divide the RO system GPD by that factor, and you will get the temperature-corrected output.
