摘要： A pleating method comprises disposing a filter material on a support surface and compressing a portion of the filter material between first and second pleating surfaces to form a pleat, where at least one of the pleating surfaces is curved or extends at an acute angle with respect to a support surface.

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.
摘要翻译： 公开了一种流体处理元件，例如过滤元件，其可在死端模式或横流模式中操作。 在某些实施例中，流体处理元件包括形成为轴向延伸的褶皱的多层复合材料。 在某些其它实施例中，相邻的褶皱处于铺设状态，并在它们的高度的大部分上彼此挤压。 流体处理元件可以是紧凑的，但具有可用于流体处理的大的表面积。 还公开了流体处理元件和方法，特别是全氟聚合物流体处理元件和方法，用于将材料从一种流体流扩散到另一种流体流中，例如用于将臭氧转移到水中。 进一步公开的是用于流体处理元件的横流清洗的装置和方法。
