Completely revised and updated, Treatment Wetlands, Second Edition is still the most comprehensive resource available for the planning, design, and operation of wetland treatment systems. The book addresses the design, construction, and operation of wetlands for water pollution control. It presents the best current procedures for sizing these systems, and describing the intrinsic processes that combine to quantify performance.

The Second Edition covers:

  • New methods based on the latest research
  • Wastewater characterization and regulatory framework analyses leading to detailed design and economics
  • State-of-the-art procedures for analyzing hydraulics, hydrology, substrates and wetlands biogeochemistry
  • Definition of performance expectations for traditional pollutants such as solids, oxygen demand, nutrients and pathogens, as well as for metals and a wide variety of individual organic and inorganic chemicals
  • Discussion of methods of configuration, construction, and vegetation establishment and startup considerations
  • Ancillary benefits of human use and wildlife habitat
  • Specific examples of numerous applications
  • Extensive reference base of current information

The book provides a complete reference that includes: detailed information on wetland ecology, design for consistent performance, construction guidance and operational control through effective monitoring. Case histories of operational wetland treatment systems illustrate the variety of design approaches presented allowing you to tailor them to the needs of your wetlands treatment projects. The sheer amount of information found in Treatment Wetlands, Second Edition makes it the resource you will turn to again and again.

Page 3 - Nature in giving natural birth to a desirable wetland. Constructed rice paddies have been responsible for feeding more people than any other enterprise on earth. 6.1 INTRODUCTION Natural wetlands are land areas that are wet during part or all of the year because of their location in the landscape. Historically, wetlands were called swamps, marshes, bogs, fens, or sloughs, depending on existing plant and water conditions and on geographic setting. Wetlands are frequently transitional between uplands...
Page 14 - Widespread use of constructed wetlands may provide a relatively simple and inexpensive solution for controlling many water pollution problems facing small communities, industries, and agricultural operations.
Page 11 - Emergent vegetation vascular, rooted plant species containing structural components that emerge above the water surface, including both herbaceous and woody plant species Natural wetlands have been used as convenient wastewater discharge sites for as long as sewage has been collected (at least 100 years in some locations). Examples of old treatment wetland sites can be found in Massachusetts, Wisconsin, Florida, and Ontario. Judging by the growing number of wetlands built for wastewater treatment...
Page 14 - Although some natural wetlands have been effectively used for water quality improvement, we do not wish to encourage additional use. We have recently become aware that natural wetlands are valuable resources that must not be wasted. Much remains to be learned about their many values and functions and the long-term consequences of wetland destruction.
Page 19 - However, the first information about the use of constructed wetlands with emergent vegetation appeared only in the early 1990s (Juwarkar et al., 1992). During the IWA conference in China in 1994, many papers on both horizontal and VF constructed wetlands from Asia, and especially China, were presented (Figure 1.21).

Page 18 - Sometimes, the aim is to provide phosphorus polishing after chemical treatment and a buffer in case of treatment failure in the conventional treatment plant (Sunblad, 1998) (Figure 1.19).
Page 19 - Since 1980, research has been conducted in Brazil on the possibility of the use of water hyacinth ponds in combination with vertical upflow constructed wetlands planted with rice (Salati, 1987).
Page 19 - Tanner et al. (2000), constructed wetlands had been adopted enthusiastically by many New Zealand communities as a cost-effective means of secondary and tertiary wastewater treatment.
Page 17 - FWS wetland in 1967 (Veenstra, 1998). The wetland had a design depth of 0.4 m and the total area was 1 ha.
