This title presents the proceedings of the 1st International Conference, Lyon, France, 27th-29th June 1990. The book presents the specialist and those less familiar with water treatment and environmental management with up to date information from a range of international workers. The conference was a forum at which interest groups representing the research community, water companies, regulatory bodies, and designers and operators of plant were beneficially brought into contact. The spirit of information exchange is retained in this book.
