Wastewater treatment for pollution control and reuse [Book] / Soli J. Arceivala, Shyam R. Asolekar.

Includes index

This title cover the following important topics: Ecosystem approach in warm climates; Mechanized biological and physico-chemical treatment methods; Natural treatment methods - ponds, lagoons, constructed wetlands; Power-saving UASBs and decentralized systems; Resource recovery and reuse for creating new water resources; Reuse in industries and agriculture; and, Planning treatment plants. The last edition of this successful book dealt with disposal of wastewater for pollution control. The current edition, "Wastewater Treatment for Pollution Control and Reuse" has been thoroughly revised and extends the discussion to the many benefits and various methods for reusing wastewater. New chapters on reuse of wastewater and use of physico-chemical treatment methods, including membrane technologies that are critical for reuse, have been added. Besides the mechanized methods of wastewater treatment the authors have discussed other methods which are not only simple, natural and cost-effective, but also more dependable, especially in developing countries with warm weather. For example, the natural treatment methods - algal, hyacinth and duckweed ponds, and constructed wetlands which are now gaining worldwide acceptance. Besides new additions, the existing content has been significantly updated and made more meaningful to present day problems with the coverage of decentralized systems, sludge management, overall design of treatment plants and a thorough discussion of the factors that affect sustainable waste management. Very importantly, from their vast experience, the authors also describe how to retrofit sanitation in slums and shantytowns and outline methods to clean polluted water courses running through big cities and towns. This title highlights: simpler, more cost-effective treatment methods; a new section on groundwater recharge; a special section on retrofitting sanitation in slums, shantytowns; water conservation and reuse in industry and agriculture; case studies of wastewater treatment plants; design data with plenty of solved examples; and, interesting topics for research and development. It is useful for: faculty and graduate students of environmental, civil and chemical engineering departments; professionals from the industry, public bodies and consulting firms concerned with the control of water pollution and reuse of water; and, pollution control agencies, municipal corporations and town planning departments.
