Download or read book Slow Sand Filtration for Disinfection of Secondary Effluent from a Wastewater Treatment Plant written by Kyle Fuller and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-cost, reliable disinfection of secondary effluent is needed at wastewater treatment plants in small communities in developing countries to reduce pathogens to a level required for reuse. There is currently a wastewater treatment plant in Sololá, Guatemala that reuses all of the effluent for crop irrigation. The reuse of this wastewater poses a public health risk to the community because the treatment plant lacks disinfection. In treatment plants such as this, a simple, gravity-fed disinfection system is needed. Five pilot scale slow sand filters were tested in three phases to determine the feasibility of slow sand filtration as a disinfection step in small wastewater treatment facilities, as well as to characterize the level of treatment achieved in the process. In the first phase, secondary effluent from the UC Davis treatment plant served as the influent to the sand filters. The time required between maintenance events in Phase 1 ranged from 7 to 114 days. In the second phase, effluent from a pilot scale wastewater treatment system (i.e. a septic tank treating municipal wastewater from UC Davis followed by a plastic-media trickling filter) intended to replicate the treatment system in Sololá was used to feed the sand filters. The third phase focused on investigating the effect of various sand sizes on maintenance frequency and treatment capability. The experimental results indicate that when fed low-turbidity influent water (e.g.

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.

This book was released on 2018-09-12 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an excellent balance between theory and applications in the ever-evolving field of water and wastewater treatment Completely updated and expanded, this is the most current and comprehensive textbook available for the areas of water and wastewater treatment, covering the broad spectrum of technologies used in practice today—ranging from commonly used standards to the latest state of the art innovations. The book begins with the fundamentals—applied water chemistry and applied microbiology—and then goes on to cover physical, chemical, and biological unit processes. Both theory and design concepts are developed systematically, combined in a unified way, and are fully supported by comprehensive, illustrative examples. Theory and Practice of Water and Wastewater Treatment, 2nd Edition: Addresses physical/chemical treatment, as well as biological treatment, of water and wastewater Includes a discussion of new technologies, such as membrane processes for water and wastewater treatment, fixed-film biotreatment, and advanced oxidation Provides detailed coverage of the fundamentals: basic applied water chemistry and applied microbiology Fully updates chapters on analysis and constituents in water; microbiology; and disinfection Develops theory and design concepts methodically and combines them in a cohesive manner Includes a new chapter on life cycle analysis (LCA) Theory and Practice of Water and Wastewater Treatment, 2nd Edition is an important text for undergraduate and graduate level courses in water and/or wastewater treatment in Civil, Environmental, and Chemical Engineering.
