Treatise on Water Science

Treatise on Water Science, Four-Volume Set Available online and in print for a limited time Water quality and management are of great significance globally, as the demand for clean, potable water far exceeds the availability. Water science research brings together the natural and applied sciences, engineering, chemistry, law and policy, and economics. The Treatise on Water Science seeks to unite these areas through contributions from a global ...

Experimental Methods in Wastewater Treatment

Over the past twenty years, the knowledge and understanding of wastewater treatment has advanced extensively and moved away from empirically based approaches to a fundamentally-based first principles approach embracing chemistry, microbiology, and physical and bioprocess engineering, often involving experimental laboratory work and techniques. Many of these experimental methods and techniques have matured to the degree that they have been ...

Renewal Engineering for Wastewater: Synthesis Report

The research presented in this report was performed in order to compile and better understand the state of the technology for wastewater pipeline renewal engineering methodologies and technologies, focusing primarily on the geographic regions of the U.S.A. An extensive literature review was performed, covering conference papers, journal articles, vendor literature, and major reports. Additionally, detailed case studies describing utility ...

Research Digest: Decision Analysis/Implementation Guidance _x0013_ Asset Management Tools Development, Phase 3

In 2006, at the direction of its members through a series of facilitated national focus groups, WERF launched a multi-year research and development project to strengthen the practice of Asset Management. The Project is called the Strategic Asset Management (SAM) project. It is comprised of four separate but integrated Tracks. Track 3 of WERFs Strategic Asset Management Project was developed to provide guidance on implementing SAM&and develop ...

Condition Assessment for Wastewater Pipelines: Synthesis Report

The research results presented in this report were compiled to provide a clearer understanding of the state of the technology for wastewater pipeline condition assessment methodologies and technologies, focusing primarily on the geographic regions of the U.S.A. An extensive literature review was performed, covering conference papers, journal articles, vendor literature, and major reports. Additionally, approximately 50 detailed case studies ...

Resource Recovery from Wastewater: A Research Agenda for Australia

Traditionally wastewater treatment involved the removal of pollutants from wastewater to allow it to be discharged to the environment. This initially concentrated on carbon removal, but as environmental requirements became more stringent it was expanded to cover nitrogen and phosphorus removal. With increasing energy costs, more stringent environmental discharge limits and greater implementation of water sensitive urban design the economic ...

Water Communication

  Water Communication aims at setting a first general outlook at what communication on water means, who communicates and on what topics. Through different examples and based on different research and contributions, this book presents an original first overview of “water communication”. It sets its academic value as one distinct scientific domain and provides tips and practical tools to professionals. The book contributes to avoid mixing ...

Cost Information for Wastewater Pipelines: Synthesis Report

The research presented in this report was performed in order to compile and better understand the total costs of some commonplace wastewater pipeline condition assessment and renewal engineering methodologies and technologies in the U.S. An extensive literature review was performed, covering all pertinent sources from the body of knowledge. Additionally, detailed case studies describing utility wastewater pipeline condition assessment and ...

Management Practice for Wastewater Pipelines: Synthesis Report

This report presents state-of-the-art literature and current practice review of management practices for wastewater pipelines. These practices focus on the pipe condition evaluation and prediction, risk analysis, and renewal prioritization. In the background part, this report introduced the basic concept and core questions of asset management. The linkage between this research focus and the asset management core questions were introduced. The ...

Research Roadmap: Towards an Economic Decision Methodology for Remaining Asset Life

This report is an output of the fourth research track (Track 4) of WERF’s strategic asset management research program ‘Asset Management Communication and Implementation’ (RFPP #06-SAM-1 CO). Track 4 was developed to address ‘remaining asset life’, with the overall objective of contributing to the development of techniques, tools and methods for estimating residual life of wastewater assets. Track 4 research was planned to be undertaken in a ...

Development of Design Criteria for Denitrifying Treatment Wetlands

Subsurface wetlands are well suited for on-site applications because they provide odor and vector control and they mitigate public access issues (U.S. EPA, 1993). Artificial subsurface wetlands are typically designed with an inert rock medium, can be either planted or unplanted, and are designed so that the water flows below the surface of the wetlands through the porous medium. The medium provides a surface area for the growth of bacterial ...

Nitrogen Removal and Sustainability of Vertical Flow Constructed Wetlands for Small Scale Wastewater Treatment

The goals of environmental sustainability, through minimizing resource use, maximizing energy efficiency, reducing waste emissions, enabling recycling, and increasing resilience are becoming primary in wastewater treatment, along with traditional goals of protecting human health and water quality. Sustainable designs, defined as design of human/industrial systems to ensure that use of natural resources and cycles do not lead to diminished ...

Trace Organic Chemicals in Biosolids-Amended Soils: State-of-the-Science Review

The presence of trace organic chemicals (TOrCs) in municipal biosolids in the U.S. has received considerable attention by the public and scientific community over the last several years.  Of particular concern is whether the presence of TOrCs in biosolids results in significant risks to public health and the environment upon land application of the biosolids.  While the U.S. Environmental Protection Agency has evaluated the risks associated with ...
