Conventional methods for designing water systems in industrialized countries are not appropriate in developing countries. Despite this, the use of sophisticated technologies worldwide is widespread, although in many cases it is inappropriate. There is a lack of information for those wishing to learn and apply many of the practices which are suitable for the developing world, and which can be easily operated and maintained; this book is designed to fill that gap. Now available again in print, Surface Water Treatment for Communities in Developing Countries is addressed to planners and engineers responsible for the design of water treatment plants to be built in Africa, Asia and Latin America. In particular, it is intended for small or isolated communities which may need to employ technologies which do not depend on capital-intensive mechanization and instrumentation. Many of the technologies identified in this text minimize the need for support technologies and highly skilled technicians, and some are experimental.
