Abstract
A process is disclosed for monitoring the integrity of hollow fiber filtration modules and for detecting leaks of treated liquid through a fiber completely or partially broken. It operates continuously and in filtration mode, without production shutdown. The process includes detecting the noise caused by the passage of the liquid through a ruptured fiber. The noise signal thus obtained is amplified. The amplified signal thus obtained is compared with a threshold noise level, within the same range of frequencies, which is characteristic of intact modules, this comparison making it possible to detect whether or not the module is intact.
