Book excerpt: This study evaluated the performance of sand (ES: 0.17 mm, UC: 3.13) and crushed recycled glass (ES: 3.59 mm, UC: 4.18) in pilot-scale subsurface filters treating municipal wastewater. The system provided on-site treatment for secondary lagoon effluents from the Village of Dunnottar, on the southwest shore of Lake Winnipeg, MB. Filters operated at a 24-hour HRT, with active treatment seasons from May to September. System performance was assessed over a two-year period (2017 - 2018), with regards to total suspended solids (TSS), chemical oxygen demand (COD), nitrogen (N) and phosphorus (P). TSS were removed equally well in sand and glass filters, with removal efficiencies above 90%. Sand and glass filter effluents contained mostly dissolved COD, except within the first month of operation, during which both media failed to achieve local BOD guidelines. Dissolved COD removal was 29% less in glass, due to smaller media surface area. NH4+-N reductions exceeded 90% in both filters. Effluent N guidelines were always met by sand filters, whereas glass exceeded the limit 33% of the time in 2018. Both sand and glass failed to reduce P below 1 mg/L. Sand filters seemed to predominantly remove P through mineral precipitation with Ca and Mg compounds. This contributed to concretion (hardening) of top sand filter layers. P removal was significantly less in glass, due to decreased Ca availability within the media. Obtained results indicate that crushed recycled glass can be used as filter media in tertiary wastewater treatment systems, especially to remove TSS, COD and NH4+-N.

Download or read book Recent Progress in Slow Sand and Alternative Biofiltration Processes written by Rolf Gimbel and published by IWA Publishing. This book was released on 2006-03-31 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts intensify to decrease the presence of disease-causing microorganisms and disinfection by-products in drinking water, to minimize microbial regrowth potential in distribution systems, and where operator skill levels are emphasized. Recent Progress in Slow Sand and Alternative Biofiltration Processes provides a state-of-the-art assessment on a variety of biofiltration systems from studies conducted around the world. The authors collectively represent a perspective from 23 countries and include academics, biofiltration system users, designers, and manufacturers. It provides an up-to-date perspective on the physical, chemical, biological, and operational factors affecting the performance of slow sand filtration (SSF), riverbank filtration (RBF), soil-aquifer treatment (SAT), and biological activated carbon (BAC) processes. The main themes are: comparable overviews of biofiltration systems; slow sand filtration process behavior, treatment performance and process developments; and alternative biofiltration process behaviors, treatment performances, and process developments.

Download or read book Design of Recirculating Sand Filters Using a Standardized Methodology written by JL. Ball and published by . This book was released on 1997 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recirculating sand filter is a successful wastewater treatment system for producers of small to medium (2 to 4000 m3/day or 500 to 1,000,000 gallons/day) wastewater flows. This cost effective, low-maintenance technology provides ideal treatment systems for parks, schools, office complexes, resorts, and even small communities with effluent sewer collection systems. Space requirements are reasonably small, construction costs are moderate, and maintenance and monitoring do not require highly trained personnel. The recirculating sand filter purifies septic tank effluent sufficiently that it can be disposed subsurface in most soils, or, where allowed, disinfected and disposed into surface waters.

Download or read book Masters Theses in the Pure and Applied Sciences written by W. H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing. house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Download or read book Natural Wastewater Treatment Systems Second Edition written by Ronald W. Crites and published by CRC Press. This book was released on 2014-03-14 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calling for ecologically and economically sound wastewater treatment systems, the authors of Natural Wastewater Treatment Systems explore the use of wetlands, sprinkler or deep irrigation, groundwater recharge, and other natural systems as sustainable methods for the treatment and management of wastewater. Based on work by prominent experts in natural waste treatment, this text provides a thorough explanation on how soil and plants can successfully sustain microbial populations in the treatment of wastewater. Determining that natural systems cost less to construct and operate, and require less energy than mechanical treatment alternatives, this book also explains how these processes produce lower amounts of residual solids, and use little or no chemicals. What’s New in the Second Edition: This revised edition includes current design and regulatory and operational developments in the natural wastewater treatment field. It provides detailed examples and analyses along with significant operational data in each chapter. It also considers how processes provide passive treatment with a minimum of mechanical elements, and describes new approaches to partially mixed ponds, including dual-powered aeration ponds. Introduces the planning procedures and treatment mechanisms responsible for treatment in ponds, wetlands, land application, and soil absorption systems Provides new case studies of constructed wetlands and water reuse systems Presents design criteria and methods of pond treatment and pond effluent upgrading Describes constructed wetlands design procedures, process applications, treatment performance data, and land treatment concepts and design equations Includes information on constituents of emerging concern (CEC) and their fate in natural systems The text discusses wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. It describes residuals and biosolids management, including nitrogen removal pretreatment methods, and uses U.S. customary and metric units in all chapters. It presents case studies of new applications of natural systems and includes worked examples of design equations for ponds and land treatment. It also provides a biosolids regulatory update from a top EPA scientist, and algae reduction technologies for ponds and wetlands. Designed for practicing wastewater engineers and scientists involved in the planning, design, and operation of ponds, wetlands, land treatment, biosolids, and onsite soil-based treatment systems, the book integrates many natural treatment systems into one single source.
