To provide 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, the fluid treatment element and the method, particularly an all fluoropolymer fluid treatment element and the method, are for diffusively transferring a material from one fluid stream to another fluid stream, for example, for transferring ozone into water. Further, a device and a method are for crossflow cleaning of the fluid treatment elements.
