Integrity testing

Integrity testing Motian membrane ultrafiltration membrane module is completeness inspection before they leave the factory. If the user is in the process of installation and use wire fracture caused by membrane, influence on water quality. This is where the component for the integrity detection. Component integrity detection principle is as follows: after membrane wetting, joined in the side of the membrane filaments compressed air, when the air pressure is below the bubble point pressure, the porosity of membrane can still moist, in addition to spread out in very small amounts of air flow, there is no clear air through wet film hole. But if film defects (e.g., fiber breakage), are far lower than bubble point pressure air will overflow at the defect observed in fluid-filled membrane silk side of bubbles in a row, or the gas side of the pressure change situation, can membrane filaments of the judgment and the integrity of the component.
