Upgrading Water Treatment Plants is a comprehensive and practical guide providing the technical detail required to upgrade existing water treatment plants to increase processing efficiency and improve overall quality without the need for substantial investment into new physical plant installation.
Based on practical experience and field tested methodology, this book is an invaluable reference for civil engineers, treatment plant managers and water scientists in consultancies, water utilities, government agencies and international organisations concerned with public health and water quality.
