This book provides a detailed understanding of a new, highly innovative natural wastewater treatment method called Engineered Bioreactors (EBs), which have been shown to provide superior removal methods for many kinds of pollutants and contaminants. Treatment using EBs involves passing wastewater through excavated basins (cells) in which microbes are introduced using fixed films on permeable substrate media. The book traces the development of the biological and ecological Engineered Bioreactor technology and presents information on the types, morphologies, testing methods for, designs,...
