Description
Fully revised and extensively updated by two of the world’s leading experts in the field, taking into account current UK, EU, and USA water-quality standards and treatment technologies. This fourth edition of a best-selling text provides comprehensive contemporary practical guidance and remains the definitive reference for all those involved in water-treatment systems. The book focuses on the issues of most interest to practising engineers, summarizing the key issues and criteria in short and accessible sections, but with additional theory to explain and support the treatment processes considered.
The new edition includes two new chapters on private water supplies and water safety plans; new content on requirement for risk assessments in England and Wales and water re-use (legislation, present and future, treatment). Also included is expanded coverage of algae, clostridium, solids recirculation clarifiers and alternative dewatering systems. Contents
