Morgan Belmont, CA Thomson/Brook/Cole 2004 This text has two unifying themes: materials balances and environmental ethics. First, the book demonstrates that environmental problems need to be solved using a holistic approach instead of a fragmented, single-pollution or single-medium approach. By using the concepts of materials balances, reactions, and reactors, the authors integrate and unify the presentation of water supply, waste-water treatment, air pollution control, and solid and hazardous waste management.
