This book is divided into three sections: the first reviews the main processes available for treating water for drinking (potable) purposes, the second goes into some detail about the design and operation of the non-filtration (clarification) processes, and the third deals exclusively with filtration and related applications. It is intended as a source of practical information rather than a theoretical research treatise and includes discussion of component parts of the process units with reasons for design features as well as operating principles.This book fills a gap between general reviews and research papers, and contains much information which is based on experience passed down within organisations and which tends not to be published.


Part 1 General concepts: introduction and early history; treatment processes. Part 2 Primary treatments: the behaviour of particles; equipment hydraulics; chemical reaction engineering - continuous flow systems; pretreatments; non-flocculating settlement units; single pass flocculating settlement tanks; recirculating clarifiers; floc blanket (fluidised bed) clarifiers; pulsed and unpulsed; lamellar clarifiers; disolved air flotation; other treatment processes; precipitation softening; sludge treatment and disposal. Part 3 Granular media filtration: the structure and hydraulics of granular filtration beds; process mechanisms; process design; conditioning of the feed suspension; back ashing; filter floors; top slide design; operation and control of multifilter installations; filter design; upflow filtration; continuous filters; biological applications; miscellaneous applications; commissioning and problems; filter media.
