Description
INDUSTRIAL ULTRA-LOW PRESSURE RO MEMBRANE SERIES
Pacific industrial ultra-low pressure (ULP) membrane can achieve high water production rate and high desalination rate in relatively low operating pressure with low energy consumption. Its operating pressure can be as low as 100 psi, which makes it suitable for desalinating water with salt content less than 1500–2000 ppm. It is widely applied in food processing, drinking water, electricity water supply, electronics and biotechnology industry, pharmaceuticals and other fields.
