Abstract: Low pressure membrane systems are used for microorganisms control in water treatment processes. In this article, the efficiency and reliability of this process is evaluated. Microorganism rejection was shown to be effective in the low pressure membrane system provided that membrane pore size is smaller than the microorganism size and membrane fibers intact. The following techniques for monitoring membrane integrity are the use of particle counters, particle monitors, turbidimeters, bubble point test, air pressure test and sonic sensors.
