Product Description

ULP series :Ultra-Low Pressure Compound RO membrane Element

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.
