Membrane integrity is in an interesting combination of science, engineering, and regulations. The book introduces the reader to the subject in the context of drinking water filtration. Both theoretical and practical aspects of membrane integrity testing are discussed along with historical and future technologies. Discussed are the types and causes of integrity breaches, tests to perform to discover them, how to establish a membrane integrity testing program and government disinfection regulations.This indicator can be pressure decay, vacuum decay, air flow, or the flow displaced water, depending on the particular method used. The applied pressure (vacuum) is lower than the bubble point of the membrane. Because ... of the form, all those methods are based on the same working principle: flow of fluid through the membrane breach under a pressure differential during the testing. ... This method is described in great detail in the USEPAa#39;s Membrane Filtration Guidance Manual.
