  • Comprehensive guide and reference to WQM by two leading authorities
  • Explains aquatic ecosystems and industry pollutants that damage organisms
  • Details the many causes of surface water quality deterioration
  • Surveys a wide range of polluting elements, from metals to xenobiotics
  • Offers specialized understanding of the sources, effects, and minimization of industrial pollution
  • Shows the capital and cost effects of pollution control strategies

This professional reference presents specialized information about the sources of water pollution and the techniques now in use to improve water quality. Written by two of the world’s foremost water quality experts, Understanding Water Quality Management: Technology and Applications is a comprehensive guide to the technologies of treating point-source wastewater, such as outflow from industrial plants.

Beginning with an overview of how aquatic ecosystems operate the book reviews the many listed and regulated pollutants that deteriorate surface waters and harm organisms. Detailed explanations are given of the techniques employed to monitor, eliminate, and minimize a wide range of industrial pollutants.

Presented here are the strategies used by industries of all sizes to reduce listed pollutants and raise water quality to higher levels in rivers, streams, lakes, and oceans. Case studies based on recent installations, as well as economic and cost analyses, show the financial and environmental impacts of the technologies discussed.
