WATER TREATMENT UNIT PROCESSES
by David G Stevenson (Consultant, Newbury, UK)
David Stevenson gained a PhD studying the mechanism of detergent action with the British Launderers Research Association and then moved to the UK Atomic Energy Authority to develop decontamination techniques and formulations as well as involvement with Materials Science. This was followed by a move into chemical engineering in nuclear fuel preparation. In 1968, he joined Paterson Candy International, a water treatment plant contractor, as Head of Process Technology, where he remained for 23 years, being involved in the development and specification of treatment processes and equipment. After retirement, he has continued as a consultant in water treatment. For nine years, he was on the council of the Water Research Centre (later the Foundation for Water Research), and is a Visiting Professor at University College, London. He has published many papers on subjects as diverse as detergent action, crystallisation, particle granulation, decontamination and many aspects of water treatment processes and plant.
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papers, and contains much information which is based on experience passed down within organisations and which tends not to be published.
