This book was released on 2000-01-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the use of constructed wetlands as a cheaper and more effective alternative method of treating domestic wastewater in tropical environments. This book determines the technical viability of the model, with respect to treatment performance under different operating conditions and the economic competitiveness of technology in Uganda and across the region. The Pilot Constructed Wetland investigated in this study was situated at the National Water and Swerage Corporation's Jinja Sewage Works at Kirinya, Uganda. The study revealed the economic viability of constructed wetland systems in the tropical regions. These could be established at competitive costs with waste stabilisation ponds.

Download or read book Constructed Wetlands for Wastewater Treatment in Hot and Arid Climates written by Alexandros Stefanakis and published by Springer Nature. This book was released on 2022-10-11 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
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 Urban Waste and Sanitation Services for Sustainable Development written by Bas van Vliet and published by Routledge. This book was released on 2013-11-12 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban sanitation and solid waste sectors are under significant pressure in East Africa due to the lack of competent institutional capacity and the growth of the region’s urban population. This book presents and applies an original analytical approach to assess the existing socio-technical mixtures of waste and sanitation systems and to ensure wider access, increase flexibility and ecological sustainability. It shows how the problem is not the current diversity in waste and sanitation infrastructures and services and variety of types and scales of technology, of formal and informal sector involvement, and of management and ownership modes. The book focuses instead on the lack of an integrative approach to managing and upgrading of the various waste and sanitation configurations and services so as to ensure wider access, flexibility and sustainability for the low income populations who happen to be the main stakeholders. This approach, coined "Modernized Mixtures", serves as a nexus throughout the book. The empirical core addresses the waste and sanitation challenges and debates at each scale - from the micro-level (households) to the macro-level (international support) - and is based on the results of a five-year-long interdisciplinary, empirical research program. It assesses the socio-technical diversity in waste and sanitation and provides viable solutions to sanitation and waste management in East Africa. This book provides students, researchers and professional in environmental technology, sociology, management and urban planning with an integrated analytical perspective on centralized and decentralized waste and sanitation configurations and tools for improvement in the technology, policy and management of sanitation and solid waste sectors.

Download or read book Treatment of Municipal Wastewater Using Constructed Wetland written by Diana Madi and published by . This book was released on 2009 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Municipal wastewater is one of the major concerns of the environment problems. As the wastewater is found to be highly contaminated, it could not be discharged directly into the environment. Therefore, wastewater treatment is essential to minimize the effect of the contaminants to nature. Based on previous studies, constructed wetland system (CWS) was proved to have high efficiency in treating industrial wastewater with low operating and maintenance cost. The industrial wastewater studied was food waste which was taken from UMP's cafeteria drainage system . In this research, lab scale of free water surface constructed wetlands was designed with the water lettuce (Pistia Stratiotes) as the wetland plant. The parameter studied including ammonia nitrogen (NH3-N) and orthophosphate (Po43-). In order to investigate the effectiveness of the systems, three variables were studied which were the number of cycle (1 and 2), the wastewater concentration (dilute and non-dilute) and the physical appearance of the plants during the treatment. The results showed that NH3-N was removed at high removal efficiency meanwhile Po43-removal appeared at low removal efficiency. Both NH3-N and Po43- removal showed better results in the CWS with 2 cycles. In term of the different municipal wastewater concentration variable, the CWS with non-dilute sample showed the highest removal efficiency for NH3-N and municipal wastewater concentration with dilute sample (DF=20) showed the highest removal efficiency for Po43-. For plant growth observation, at the end of the treatment, many of the water lettuces were wilted. As conclusion, this study showed that constructed wetland can remove contaminant in cafeteria wastewater.-Author-
