Category Introduction
The Ultra Low Pressure RO Membrane series is suitable for desalination of surface water, groundwater, tap water, and municipal water sources with concentrations below 2000 ppm.
It achieves high water flux and desalination rates at low operating pressures, reducing operating costs for associated pumps, piping, and vessels, thereby improving economic efficiency.
It is widely used in a variety of industries, including packaged water, drinking water, boiler feed water, food processing, and pharmaceutical manufacturing.
