Download or read book Feasibility Design Criteria and O M Requirements for Small Scale Constructed Wetland Wastewater Treatment Systems written by S. Wallace and published by IWA Publishing. This book was released on 2006-07-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expanding use of decentralized wastewater management has resulted in an increased interest in small-scale wetland treatment systems. However, there is limited information available on the use, distribution of and performance of these small-scale systems. The purpose of this study was to address this knowledge gap by developing criteria for the feasibility, design, operation, and maintenance of small-scale wetland treatment systems. Monitoring data from the assembled small-scale wetland database was used to develop sizing criteria for FWS and VSB wetlands. Loading rates and corresponding effluent quality were developed for BOD, TSS, TKN, phosphorus, and fecal coliform bacteria. Where there was adequate data, the variation in monthly vs. annual average effluent concentration was assessed to provide a factor-of-safety approach to wetland sizing. Information on internal processes, hydraulic design, operation, maintenance, cost, and industrial applications of constructed wetlands is also presented in this report.

Download or read book Artificial or Constructed Wetlands written by María del Carmen Durán-Domínguez-de-Bazúa and published by CRC Press. This book was released on 2018-06-15 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial or constructed wetlands are an emerging technology particularly for tropical areas with water scarcity. For big cities, the sustainable management of water resources taking into account proper use is always challenging. The book presents case studies illustrating the above. As plants and microorganisms are a fundamental part of the correct functioning of these systems, their contribution to the degradation of the organic matter and to the removal and transformation of the pollutant compounds present in the wastewaters is also a highlight of this book.
Download or read book Wastewater Treatment in Constructed Wetlands with Horizontal Sub Surface Flow written by Jan Vymazal and published by Springer Science & Business Media. This book was released on 2008-07-15 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Wetland Systems written by Miklas Scholz and published by Springer Science & Business Media. This book was released on 2010-11-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetland Systems covers broad water and environmental engineering aspects relevant for the drainage and treatment of storm water and wastewater. It provides a descriptive overview of complex ‘black box’ treatment systems and the general design issues involved. Standard and novel design recommendations for predominantly constructed wetlands and related sustainable drainage systems are given to take into account the interests of professional engineers and environmental scientists. Wetland Systems deals comprehensively with not only the design, operation, maintenance and water quality monitoring of traditional and novel wetland systems, but also covers: • Analysis of asset performance • Modelling of treatment processes • Performances of existing infrastructure • Sustainability and economic issues Solutions to pressing water quality problems associated with constructed treatment wetlands, integrated constructed wetlands, farm constructed wetlands and storm water ponds, and other sustainable biological filtration and treatment technologies linked to public health engineering are explained. Case study topics are diverse: natural wetlands and constructed treatment wetlands; sustainable water management; and specific applications, such as wetlands treating hydrocarbons. The research projects discussed are multi-disciplinary, holistic, experimental and modelling-orientated. Wetland Systems is a useful reference for the design and operation of wetland systems by engineers and scientists working for the water industry, non-governmental organisations, local authorities and governmental bodies. It is also a valuable text for undergraduate and postgraduate students, lecturers and researchers in civil and environmental engineering fields.

Download or read book Wetlands for Tropical Applications written by Norio Tanaka and published by World Scientific. This book was released on 2011 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic exposition of the design features of constructed wetlands, and their management (in terms of siting, physical maintenance, and operation). Only very few books (or chapters) have been published on constructed wetlands in tropical conditions and none are current. The selection of plant species, managing their growth and harvesting cycles, and the impact these have on the attenuation of organic and inorganic pollutants, nutrients, and pathogens would be of interest to students and practitioners of the art working under tropical conditions. The potential of constructed wetlands as a low-cost intervention for developing countries in tropical regions that faced water pollution problems, in particular, deserves to be explored systematically.

This book was released on 2008-04-22 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, constructed wetlands for wastewater treatment are a widely used technology for treatment of various types of wastewaters. The International Water Association (then International Association on Water Pollution Research and Control) recognized wetlands as useful tools for wastewater treatment and est- lished the series of biennial conferences on the use of wetland systems for water pollution control in 1988. In about 1993, we decided to organize a workshop on nutrient cycling in natural and constructed wetlands with the major idea to bring together researchers working on constructed and also natural wetlands. It was not our intention to compete with IWA conferences, but the workshop should rather complement the series on treatment wetlands by IWA. We believed that the exchange of information obtained from natural and constructed wetlands would be beneficial for all participants. And the time showed that we were correct. The first workshop took place in 1995 at T?ebo? in South Bohemia and most of the papers dealt with constructed wetlands. Over the years we extended the topics on natural wetlands (such as role of wetlands in the landscape or wetland restoration and creation) and during the 6th workshop held at T?ebo? from May 30 to June 3, 2006, nearly half of 38 papers presented during the workshop dealt with natural wetlands. This workshop was attended by 39 participants from 19 countries from Europe, Asia, North and South Americas and Australia. The volume contains 29 peer-reviewed papers out of 38 papers which were presented during the workshop.

Download or read book Eco Engineered Bioreactors written by James Higgins and published by CRC Press. This book was released on 2017-11-22 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive understanding of a highly innovative method of natural wastewater treatment using advanced in-groundbioreactors called Eco-Engineered Bioreactors (EEBs), and traces their evolution from the earliest aerated gravel bed versions once known as Engineered Wetlands (EWs) and now known as BREW Bioreactors (BBRs) all the way to today’s wide slate of aerobic and anaerobic varieties. Treatment using EEBs involves passing wastewaters through excavated basins in which they contact fixed films of microbial consortia on permeable substrate media. Written from the perspective of ecological engineers designing EEBs, this guide covers updated information on the state-of-the-art for EEBs, covering their morphologies, testing methods, designs, operations, and microbiology.
