Constructed Wetlands in the Sustainable Landscape


Book Description

Constructed wetlands are gaining worldwide acceptance as effective, low-cost, and low-impact alternatives to unsightly, high-impact wastewater treatment facilities. The creative involvement of today's planners, landscape architects, developers, environmental engineers, and public officials is helping to maximize the potential of these wetland habitats—from their aesthetics to their multiple uses as water treatment plants, wildlife refuges, and recreational or educational facilities. Yet, to date, the literature has paid no attention to these aspects, focusing instead on the technical side of wetlands construction and function. Constructed Wetlands in the Sustainable Landscape is the first book to integrate aesthetic design and planning issues with the technical aspects of wetlands engineering. Renowned landscape architect Craig S. Campbell and engineer Michael H. Ogden clearly demonstrate how the successful development and management of multifunctional, sustainable wetland habitats depend on harnessing the knowledge and working principles of a number of disciplines. Richly illustrated with real-world case studies, the book: Covers the concept of sustainable development and the nature of wetland processes. Discusses designs for new and existing municipal and small community wastewater treatment facilities. Contains examples of on-site planning for, and management of, stormwater renovation, single-family residential systems, and multiple-use systems. Examines landscape engineering and planning for ponds, urban wildlife, and ecological art. Clearly written and accessible to nonengineers and nonscientists, Constructed Wetlands in the Sustainable Landscape is a crucial guide for landscape architects, environmental engineers, planners, developers, and others responsible for the design and management of our built environment.




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.







Ultraviolet Disinfection for Wastewater


Book Description

Developed in conjunction with the International Ultraviolet Association, Ultraviolet Disinfection for Wastewater: Low-Dose Application Guidance for Secondary and Tertiary Discharges serves as a guide for consultants, wastewater utilities, and operators and provides introductory information on the advantages (and disadvantages) of UV disinfection compared to other commonly used technologies. It also provides valuable information to regulatory agencies who review applications for the use of UV disinfection systems in water resource recovery facilities that are subject to discharge limits for bacteria under National Pollutant Discharge Elimination System permitting. Providing specific case study examples, UV Disinfection fills an existing gap in the design guidance that is available for UV disinfection for low-dose applications, which includes disinfection of secondary and tertiary wastewater effluent discharges to meet NPDES compliance. Table of Contents Chapter 1: Introduction Chapter 2: Ultraviolet Disinfection Process Concepts and Equipment Systems Chapter 3: Bioassay Methods to Determine the Ultraviolet Dose (Fluence) Delivery of an Ultraviolet System Chapter 4: Innovations and Advances in Ultraviolet Reactor Analysis and Validation Chapter 5: Process Design and System Sizing Chapter 6: Equipment Selection, Facility Design, and Project Delivery Chapter 7: Ultraviolet Project Delivery, Startup, and Commissioning Chapter 8: Operational Considerations Chapter 9: Case Studies
