Over 1500 definitions of terms for solid/liquid separation, air/gas/dust separations, filter media, contamination control etc. – from Abatement and Abrasion to Zone Settling and Zwitterion – plus a list of abbreviations and acronyms – are provided in this quick reference dictionary (303 pages).  With clear, bold type entries it gives a direct lead into the detail and use of equipment, and defines precisely the meanings of terminology. 

With this new Dictionary the authors have put together an authoritative and up to date text which is cross-referenced and illustrated by over 400 diagrams and photographs.  The aim is to provide a source of reference for all practitioners of filtration and separation, and a valuable educational and training resource.

It is an indispensable book for plant engineers, technicians, operators, and all who work with filtration and separation technology as buyers, users, and suppliers of equipment. It is also of value to managers in production and service industries, to graduate students and researchers, standards and health and safety inspectors, and all who have associated interests.

Successful industrial-scale separation of solids from liquids requires not only a thorough understanding of the principles involved, but also an appreciation of which equipment to use for best effect, and a start-to-finish plan for the various processes involved in the operation. If these factors are all correct, then successful separations should result. In this volume the authors provide the detailed information on filtration equipment and media which allow the reader to then consider the pre-treatment of suspensions, selection of the most appropriate equipment for the task, data analysis and the subsequent design of the processes involved for particular separations. The result is a comprehensive book which is designed to be used frequently, referred to regularly, thumbed through and made grubby in the interests of better industrial separations.

The book is available directly from the publishers Elsevier Advanced Technology.
