Ultra Low Pressure (ULP) RO Membrane
An Ultra Low Pressure Reverse Osmosis membrane is a thin-film composite (TFC) membrane engineered to operate effectively at significantly lower feed pressures than conventional RO membranes. Typical operating pressures for ULP membranes range from 5 to 10 bar (75-150 psi), compared to 15-30 bar (225-450 psi) or higher for standard brackish-water RO elements. Despite the lower driving pressure, ULP membranes deliver high water flux and excellent salt rejection owing to their highly selective polyamide active layer and optimized support structure.
Key Features
High Permeability: Specially designed for increased water passage at low pressures, yielding high productivity per unit energy.
Energy Efficiency: Reduced hydraulic pressure requirements translate directly into lower pumping energy and operating costs.
Compact System Design: Smaller pump and piping can be used, facilitating more compact and lightweight system installations.
TFC Construction: A thin polyamide active layer on a polysulfone support, with a polyester backing, ensures both performance and structural integrity.
