Constructed Wetlands for Wastewater Treatment in Cold Climates


Book Description

This volume presents 17 contributions focusing on the potential, and use of, constructed wetlands for wastewater treatment in cold climate areas. The central issues examined are the long-term experiences of such wetlands, optimum design to improve purification efficiency, the intensity of the critical processes of organic matter mineralization and nutrient retention during winter, and constructed wetland use for multiple purposes.

Constructed Wetlands for Pollution Control


Book Description

The book presents a comprehensive up-to-date survey of wetland design techniques and operational experience from treatment wetlands. This book is the first and only global synthesis of information related to constructed treatment wetlands. Types of constructed wetlands, major design parameters, role of vegetation, hydraulic patterns, loadings, treatment efficiency, construction, operation and maintenance costs are discussed in depth. History of the use of constructed wetlands and case studies from various parts of the world are included as well. Constructed Wetlands for Pollution Control will be indispensable for wastewater treatment researchers and designers, decision makers in public authorities, wetland engineers, environmentalists and landscape ecologists. Contents Biological methods for the treatment of wastewaters Types of constructed wetland Aplications of the technology Framework for interpreting and predicting water quality improvement Mechanisms and results for water quality improvement Design Plants and planting System start-up Economics Case studies Scientific and Technical Report No.8

Wetlands and Natural Resource Management


Book Description

This book provides a broad and well-integrated overview of recent major scientific results in wetland science and their applications in natural resource management issues. The contributors, internationally known experts, summarize the state of the art on an array of topics, divided into four broad areas: The Role of Wetlands for Integrated Water Resources Management: Putting Theory into Practice; Wetland Science for Environmental Management; Wetland Biogeochemistry; Wetlands and Climate Change Worldwide.




Wastewater Treatment in Constructed Wetlands with Horizontal Sub-Surface Flow


Book Description

Wetlands have been used for uncontrolled wastewater disposal for centuries. However, the change in attitude towards wetlands during the 1950s and 1960s caused the minimization of the use of natural wetlands for wastewater treatment (at least in developed countries). Constructed wetlands have been used for wastewater treatment for about forty years. Constructed wetland treatment systems are engineered systems that have been designed and constructed to utilize the natural processes for removal of pollutants. They are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The aim of this book is to summarize the knowledge on horizontal s- surface flow constructed wetlands (HF CWs) and objectively evaluate their treatment efficiency under various conditions. The information on this type of wastewater treatment technology is scattered in many publications but a comprehensive summary based on world-wide experience has been lacking. The book provides an extensive overview of this treatment technology around the world, including examples from more than 50 countries and examples of various types of wastewater treated in HF CWs.







Constructed Wetlands for Wastewater Treatment in Hot and Arid Climates


Book Description

This edited book presents the first collection of case studies and research projects on the sustainable technology of constructed wetlands for wastewater management under hot and arid climates. It is the first such work that summarizes in a single reference the current international experiences and knowledge on the implementation of this nature-based solution under these diverse and often harsh climatic conditions. It covers the relevant gap in the fragmented and limited literature by providing integrated information and documentation on the feasibility of this green technology. The book presents the treatment efficiency of constructed wetland facilities and the research output from 29 different countries across South America, Africa, Asia and Oceania, while it covers various applications such as domestic and municipal wastewater, various industrial effluents and municipal sludge. Many examples and case studies further demonstrate the potential of this technology to contribute to better address the issues of water scarcity and limited fresh water resources through circular management of treated effluents e.g. reuse in irrigation. It also discusses the various challenges and technical aspects that should be considered in such climates, along with the environmental, financial and social benefits of this technology. This work is a useful handbook and guide for professional engineers, practitioners, academics, researchers, students, and water authorities who wish to get a better understanding and first-hand information on the potential of constructed wetlands for cost-effective and sustainable wastewater management in countries with hot and arid climates.
