Filters and Filtration Handbook (hepa filter)

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) April 8, 2011 --

A book entitled FILTERS AND FILTRATION HANKBOOK is clearly stating its purpose in those words, but the primary topic---fluid purification free of contaminants by means of mechanical separation processes---requires a somewhat broader coverage than those words imply. The title of this chapter suggets that broader coverage, even if it is a little confusing, because filtration is one form of separation. The title is, in fact, shorthand for the more cumbersome phrase: “ filtration and other related forms of separation, and has been used in that way for over 40 years, as the title of a leading magazine in the industry proclaims. Throughout this book the term ‘filtration’ should thus be read as to imply that broader term (unless the context suggests the narrower definition)

So it is perhaps as well to start with some sort of definition of these terms, in the context of this HANDBOOK. FILTRATION specifically, and separation generally, refer to the act of separating one or more distinct phases from another in a process which uses physical differences in the phases(such as particle size or density or electric charge). The whole of the phase separation spectrum is illustrated in Table 1.1---the separation of distinct phases. However, as with any attempt to classify things in the real world, there is some overlap with the first half of the table: some membrane processes normally classified with filtration actually operate by molecular diffusion, while one major filtration mechanism involves adsorption(and many adsorbers act as filters as well).
