ULP (Ultra Low Pressure) series is the latest development of the era of Walton's ultra low pressure
aromatic polyamide composite membrane components used in surface water and groundwater
desalination, can achieve the same high water flux and high desalination rate under ultra low
operating pressure conditions. The operating pressure is about 2/3, which is about 99.5% of the
conventional low pressure composite film. So as to reduce the cost of investment and reverse
osmosis system of pump, pipeline, container and so on.
