4 Inch Low Energy RO Membranes

  • 4″ Low Energy, Energy Saving (ES), and Ultra Low Pressure (ULP) membrane elements are designed for low to moderate salinity feed water applications (with inlet TDS up to 2,000 ppm NaCl). Low-pressure membrane elements are rated for a test working pressure of 150 PSI (10.3 bar).
  • 4 Inch Extra Low energy Reverse Osmosis Membranes (4″ Extreme Low Pressure) They are designed for low salinity water to operate at ultra low pressure. These membrane elements are based around 100-110 PSI (around 7 bar) test working pressure, please check each membrane details below
  • Available Sizes: 4″ x 40″ and 4″ x 21″
