Filters

Abstract

There are essentially two main types of filters from a layout design point of view. There are those that are essentially ancillary fittings, such as line strainers, and those which are unit operations in their own right. Nowadays, filtration tends toward continuous operation, though batch and semibatch operation is still very important in the pharmaceutical, food, and water sectors. The most important technological advance in filtration in recent years has been the increased availability of consistent and economical membrane filters. As these tend to come in standardized packages of a fixed size, membrane plant layouts tend to be highly modularized.
