It operates under approximately two thirds of the operating pressure of regular low-pressure composite membranes, which can decrease the investment costs for such relevant facilities as pumps, pipelines, and containers, etc. and the operating cost for the RO system, thus increasing the economic efficiency.\u003c\/p\u003e\n\u003cp\u003eApplicable to desalination treatment of those water sources with NaCl lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, ULP series membrane elements are mainly applicable to such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production. \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTesting Conditions\u003c\/li\u003e\n\u003cli\u003eTesting Pressure: 225 psi (1.55Mpa)\u003c\/li\u003e\n\u003cli\u003eThe temperature of Testing Solution: 25 °C\u003c\/li\u003e\n\u003cli\u003eThe concentration of Testing Solution (NaCl): 2000ppm\u003c\/li\u003e\n\u003cli\u003epH Value of Testing Solution: 7.5\u003c\/li\u003e\n\u003cli\u003eRecovery Rate of Single Membrane Element: 15%\u003c\/li\u003e\n\u003cli\u003eOperation Limits \u0026amp; Conditions\u003c\/li\u003e\n\u003cli\u003eMax.
