This book is a state-of-the-art review of liquid filtration in the chemical process and allied industries. Interpretations of the phenomenological observations of the hydrodynamics of filtration are given in the hopes of establishing more theoretical and generalized bases of design methodology. Specific design and selection criteria are reviewed, and typical industrial problems and their solutions are presented. Nicholas Cheremisinoff is known internationally as one of the foremost engineers with Exxon and as the author of numerous books, articles and periodical contributions. Most recently his international consulting role has seen him active the Ukraine, part of the former Soviet Union, where the modernising of these industrial processes has been key. Liquid Filtration is a fundamental unit operation extensively practiced throughout the chemical process, petroleum, and allied industries. It involves the separation, removal, and collection of a discrete phase of matter existing in a dispersed or colloidal state in suspension. This separation is most often performed in the presence of a complex media structure in which physical, physiochemical and/or electrokinetic forces interact.
