Ultra Low Pressure RO Membrane Element - ProTool
RO or Reverse Osmosis, is a technology commonly used for water desalination, as well, RO removes dissolved solid and other impurities from water after advanced micro treatment.
Ultra Low Pressure RO Membrane Element - ProTool
Suitable for desalting those water sources TDS lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, etc
A Quality RO Membrane that flows 0.8 to 0.88 Gallons per Minute at Tap water pressure (70psi, 72F water) amnd 1.3 gpm when running at 110psi and 70 degrees F water temperature
Ultra Low Pressure RO Membrane Specifications:
-
Active Membrane Area: 78 sq.ft.
-
Average Permeate Production: 2500 Gallons per Day
-
Testing Pressure: 150, Temperature: 77F
-
Operating Pressure: 60psi to 150psi
-
Rejection Rate: Greater than 99%
-
Max Temperature: 113FPH
-

NOTE: Store RO membranes above 34 degrees F to avoid damaging the filters. Do not let the membranes freeze.
The following chart offer a rule of thumb guide for calculating the impact of Temperature and Pressure on the Rated capacity of a RO/DI system.
For the purposes of this chars we are using an RO system rated at 1 gpm flow @ 77F water and 80psi input pressure
We can combine these two adjustments into a table and gauge the total impact on flow for Water Temp and Input Pressure
A 1gpm Rating at 77F and 80 psi will turn into these performance measures:
