Vontron ULP21-2540 Reverse Osmosis Membrane
The Vontron ULP21-2540 is a compact and efficient ultra-low pressure reverse osmosis membrane, engineered to deliver high-performance water purification with reduced energy requirements. Designed for medium-capacity systems, it provides a permeate flow rate of 750 gallons per day (2.84 m³/d) with an impressive 99% rejection rate, ensuring high-quality, purified water.
Built with an active membrane area of 30 ft² (2.8 m²), the ULP21-2540 performs optimally under standard testing conditions (25°C water temperature, 150 psi pressure) and is ideal for residential, commercial, or light industrial RO systems. The membrane maintains a stable 15% recovery rate, balancing water efficiency with system longevity.
With a maximum working pressure of 600 psi (4.14 MPa) and feed water flow handling of up to 16 gpm (3.6 m³/h), this membrane is built for consistent, reliable operation in a wide range of water purification setups.
