摘要： The present invention includes a device for locating defective filter elements among a plurality of filter elements. The device includes a sound monitoring apparatus and a processing circuit. The sound monitoring apparatus is associated with a plurality of filter elements to detect sounds emanating from the plurality of filter elements and produce output signals indicative of the sounds. The processing circuit is coupled to the sound monitoring apparatus to determine the location of defective filter elements among the plurality of filter elements based on the output signals. The present invention also includes a probe for locating defective filter elements based on sounds emanating from the filter elements.

摘要： Disclosed is a fluid treatment element, such as a filter element, operable in a dead end mode or a crossflow mode. In certain embodiments, the fluid treatment element includes a multilayer composite formed into axially extending pleats. In certain other embodiments, adjoining pleats are in a laid-over state and pressed against each other over a substantial portion of their height. The fluid treatment element can be compact yet have a large surface area available for fluid treatment. Also disclosed are a fluid treatment element and a method, particularly an all fluoropolymer fluid treatment element and a method, for diffusively transferring material from one fluid stream to another fluid stream, for example, for transferring ozone into water. Further disclosed are a device and method for crossflow cleaning of fluid treatment elements.
