Book Synopsis Selecting Plant Species to Optimize Wastewater Treatment in Constructed Wetlands by : Carrie Renee Taylor
Download or read book Selecting Plant Species to Optimize Wastewater Treatment in Constructed Wetlands written by Carrie Renee Taylor and published by . This book was released on 2009 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constructed wetlands are used around the world for treating domestic, agricultural, and industrial wastewater, stormwater runoff, and acid mine drainage. Plants may affect efficacy of wastewater treatment through their influence on microbial activity by creating attachment sites and releasing carbon exudates and oxygen. My research investigated seasonal plant effects on wastewater treatment by monitoring water chemistry in model subsurface wetlands planted with monocultures of 19 plant species and unplanted controls. Chemical oxygen demand (COD) removal, an indicator of water quality, declined during colder temperatures in the unplanted control, likely caused by a decrease in microbial activity. In contrast, wetlands with most plant species had constant COD removal across seasons. Redox potential and sulfate concentrations were measured as indirect measurements of the oxygenation of the wastewater. Wetlands that had a decline in COD removal during cold temperatures had constant low redox potential and sulfate concentrations throughout the seasons. Wetlands with high COD removal across seasons had elevated redox potentials and sulfate concentrations during the winter, indicating elevated oxygen availability, which may offset the negative temperature effect on microbial processes. I measured root oxygen loss (ROL) in the summer and the winter to determine whether oxygen release was sufficient to influence wastewater treatment and cause seasonal and species-specific effects on water chemistry. COD removal and ROL were positively correlated at 4°C but not at 24°C; however, the amount of root oxygen release only accounted for a portion of the required oxygen to facilitate plant's influence on COD removal. Flooding tolerance was quantified for each species by comparing plants' biomass between flooded and drained conditions. Plants' botanical grouping, Wetland Indicator Status, and flooding tolerance were compared to plants' influences on wastewater treatment to determine whether easily measured plant traits can be used to identify plants that will optimize wastewater treatment. All the sedges and rushes, obligate wetlands species, and 8 of 9 flood-tolerant plants had greater COD removal than the control at 4°C, the coldest temperature incubation. These results can be applied for wetland design by selecting plant species to optimize wastewater treatment, especially in cold climates.
Book Synopsis Wetlands For Tropical Applications: Wastewater Treatment By Constructed Wetlands by : Norio Tanaka
Download or read book Wetlands For Tropical Applications: Wastewater Treatment By Constructed Wetlands written by Norio Tanaka and published by World Scientific. This book was released on 2011-06-24 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.

Book Synopsis Wastewater Treatment in Constructed Wetlands with Horizontal Sub-Surface Flow by : Jan Vymazal
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.

This book was released on 2012 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of constructed wetlands are used to treat agricultural runoff. Research was carried out on a small pond located on private property in Fairfield Township, Columbiana County, Ohio. The pond receives runoff from two small streams that drain a small cattle farm and surrounding crop land. The excess of nutrients in the pond is causing heavy growth of duckweed and algae. A constructed wetland was built to remove nutrients from the pond inflow to improve as a means of improving the water quality and making the pond more aesthetically appealing. Pre-wetland construction and post construction water quality sampling and analyses were conducted to evaluate the effectiveness of the wetland in improving water quality. Water Quality parameters included: biochemical oxygen demand, total solids, total suspended solids, Escherichia coli (E. coli), coliform, dissolved oxygen and temperature. Local wetland plant species were transplanted from two established wetland sites to populate the new constructed wetland. A plant count was performed to determine the percent growth and proliferation of the wetland plants. Statistical analysis of the pre and post wetland construction water testing results showed a significant decrease in total suspended solids in 2011 from 2010. The boxplot tests showed decreases of the average number in total suspended solids, total solids, biochemical oxygen demand, E. coli, and coliform bacteria. An increase in dissolved oxygen and temperature was also shown in the SPSS boxplot tests. The univariate test between temperature and dissolved oxygen showed a slight significance between the two parameters. The total percent growth rate for both of the wetland cells was found to be 2900%, with cattails being the dominate species.
