Download or read book Examining Reduction of Phosphorus and Copper Release from Bioretention Soil Media Components Using Phosphorus Saturation Ratio written by Norah Kates and published by . This book was released on 2019 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioretention is an effective means of treating urban runoff, however, organic soil components are known to export P and Cu. Drinking water treatment residuals (WTRs) are cost-effective P sorbents and may also be useful in Cu retention. To optimize bioretention soil mixtures (BSMs), predictive measures of P and Cu mobility are needed for application across a range of materials. A series of batch studies was conducted with WTRs and organics to determine the relationship between P and Cu export and soil physiochemical characteristics. Materials were incubated separately and in combination, and net release was calculated on a mass basis from the media. P release from combinations increased with increases in either phosphorus saturation index (PSI) or phosphorus saturation ratio (PSR), determined by oxalate or Mehlich 3 extraction, respectively. Variation in P release increased at higher PSI and PSR values, but decreased at low values (PSI
Download or read book Monitoring Phosphorus Transport and Soil Test Phosphorus from Two Distinct Drinking Water Treatment Residual Application Methods written by Jason S. Undercoffer and published by . This book was released on 2009 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Applications of manure and soils with elevated amounts of phosphorus (P) can result in surface transport of P leading to eutrophication of surface waters. Drinking water treatment residuals (WTR) have been identified as a potential best management practice to reduce the loss of P from agricultural fields. Two field simulated rainfall studies were used to investigate the efficacy of WTR to reduce P transport, reduce soil test P (STP), and determine if relationships between STP and runoff dissolved P (RDP) are altered by soil applied WTR. In the first field study, WTR was co-blended with poultry litter to achieve a range of phosphorus to aluminum molar ratios, or phosphorus saturations (Psat), two weeks prior to land application. Blending WTR at rates of 0, 7, 21, 84 g WTR kg-1 manure resulted in phosphorus saturations of 1860% (0WTR), 600% (LWTR), 200% (MWTR) and 50% (HWTR), respectively. Manure soluble P was reduced by 33, 62, and 96% by the LWTR, MWTR, and HWTR, respectively. The treatments were broadcast at 11.3 Mg ha-1 on field plots (2m X 2m) and simulated rainfall was performed prior to, immediately following application and at 1 month intervals for 3 months. Immediately following treatment application, RDP was reduced by 68% by the MWTR treatment and 97% by the HWTR treatment when compared to the RDP of the 0WTR treatment (32.9 mg L-1). These large reductions relative to previous research suggest co-blending WTR with manure prior to land application, rather than broadcasting each material separately, may be a more effective use of WTRs P-binding capability. Currently, Ohio's P-index uses total manure P as an indicator of P transport risk. Results of this study show that the P-index should be adjusted for WTR treatments. Phosphorus source coefficients determined by soluble manure P is currently used by several states and could be used in Ohio to reflect reduced P transport from WTR co-blending. Co-blending WTR with manure to achieve a final blended Psat 100% may provide the best protection of water quality and be a useful tool for WTR/manure co-blending calibration. In the second field simulated rainfall study, WTR (10 Mg ha-1) was incorporated into field plots (2m x 2m) with a wide STP range. Soil incorporated WTR reduced STP for all soil test methods following WEP (74.8%) Psat (50.2%)> M3P (40.2%)> B1P (39.5%) and RDP (39.4%), one day after WTR application. We observed positive linear relationships between Mehlich-3 P (M3P), Bray-1 P (B1P), water extractable P (WEP), and phosphorus saturation (Psat) with RDP for all runoff events. Relationships between M3P, B1P, or Psat and RDP were not significantly altered by soil incorporated WTR while the relationship formed by WEP and RDP had a significantly higher slope when soil incorporated WTR was present. Ohio's P-index currently utilizes B1P and M3P as an indicator of environmental risk of P transport. Results from this study support the use of B1P and M3P to categorize P transport risk, regardless of previous WTR applications.

Download or read book Plant Selection for Bioretention Systems and Stormwater Treatment Practices written by William F. Hunt and published by Springer. This book was released on 2014-10-28 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: As cities develop, more land is converted into impervious surfaces, which do not allow water to infiltrate. Careful urban planning is needed to ensure that the hydrologic cycle and water quality of the catchment areas are not affected. There are techniques that can attenuate peak flow during rain events and reduce the amount of metals, nutrients, and bacteria that enter the urban water cycle. This brief gives a short introduction on bioretention systems and documents the effectiveness of some 36 plant species in removing water pollutants. A summary on the maintenance requirements is also presented.
Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book excerpt: "Stormwater infiltration is the most complete approach to stormwater management. Only infiltration can simultaneously solve problems of water quality, flood control, streambank erosion, aquifer recharge, and maintenance of downstream base flows and wetland hydroperiods. Stormwater Infiltration is the first book to explain the principles of natural science on which infiltration is based, how to apply infiltration to any region of the country, and what kinds of results can be expected. It brings into one publication the complete range of necessary information on soils, vegetation, infiltration, hydrology, design criteria, site layout, construction process for surface and subsurface basins, porous paving materials, feasibility, maintenance, and performance. It draws more than half a century's actual experiences from all over the United States to place stormwater management in a context of environmental balance and quality for human life."--Provided by publisher.

Download or read book Biochar for Environmental Management written by Johannes Lehmann and published by Routledge. This book was released on 2012-05-16 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Download or read book DayWater written by Daniel R. Thevenot and published by IWA Publishing. This book was released on 2008-03-15 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European DayWater project has developed a prototype of an Adaptive Decision Support System (ADSS) related to urban stormwater pollution source control. The DayWater ADSS greatly facilitates decision-making for stormwater source control, which is currently impeded by the large number of stakeholders involved and by the necessary multidisciplinary knowledge. This book presents the results of this project, providing new insights into both technical and management issues. The main objectives of its technical chapters are pollution source control modelling, risk and impact assessment, and evaluation and comparison of best management practices. It also covers management aspects, such as the analysis of the decision-making processes in stormwater source control, at a European scale, and stormwater management strategies in general. The combination of scientific-technical and socio-managerial knowledge, with the strong cooperation of numerous end-users, reflects the innovative character of this book which includes actual applications of the ADSS prototype in significant case studies. DayWater: an Adaptive Decision Support System for Urban Stormwater Management contains 26 chapters collectively prepared by DayWater scientific partners and end-users associated with this European Research and Development project. It includes: A general presentation of the DayWater Adaptive Decision Support System (ADSS) structure and operation modes A detailed description of the major components of this ADSS prototype The assessment of its components in significant case studies in France, Germany and Sweden The proceedings of the International Conference on Decision Support Systems for Integrated Urban Water Management, held in Paris on 3-4 November 2005. The book presents the ADSS prototype including a combination of freely accessible on-line databases, guidance documents, “road maps” and modelling or multi-criteria analysis tools. As demonstrated in several significant case studies the challenge for stormwater managers is to make the benefits of urban stormwater management visible to society, resulting in active co-operation of a diversity of stakeholders. Only then, will sustainable management succeed. DayWater: an Adaptive Decision Support System for Urban Stormwater Management advances this cause of sustainable urban management through Urban stormwater management, and makes achievable (by means of risk and vulnerability tools which are included) the goal of integrated urban water management (IUWM).

Download or read book Nature Based Solutions for Wastewater Treatment written by Katharine Cross and published by IWA Publishing. This book was released on 2021-08-15 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are 2.4 billion people without improved sanitation and another 2.1 billion with inadequate sanitation (i.e. wastewater drains directly into surface waters), and despite improvements over the past decades, the unsafe management of fecal waste and wastewater continues to present a major risk to public health and the environment (UN, 2016). There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS such as treatment wetlands. There is increasing scientific evidence that treatment systems with designs inspired by nature are highly efficient treatment technologies. The cost-effective design and implementation of ecosystems in wastewater treatment is something that exists and has the potential to be further promoted globally as both a sustainable and practical solution. This book serves as a compilation of technical references, case examples and guidance for applying nature-based solutions for treatment of domestic wastewater, and enables a wide variety of stakeholders to understand the design parameters, removal efficiencies, costs, co-benefits for both people and nature and trade-offs for consideration in their local context. Examples through case studies are from across the globe and provide practical insights into the variety of potentially applicable solutions.
