Effects of Wastewater Disinfection on Human Health
Wastewater disinfection is practiced with the goal of reducing risks of human exposure to pathogenic microorganisms. Ideally, this goal is to be met without introducing other risks, such as those...
Technical Brief: Endocrine Disrupting Chemicals and Implications for Wastewater Treatment
This Technical Brief summarizes the information that is currently available from scientific research on Endocrine Disrupting Compounds (EDCs), sometimes known as hormonally active agents. It was...
Water and Wastewater Management in the Tropics
Water and Wastewater Management in the Tropics provides the necessary conceptual framework and tools to assess all appropriate aspects of water and sanitation projects in...
Mechanism and Design of Sequencing Batch Reactors for Nutrient Removal
The sequencing batch reactor (SBR) is perhaps the most promising and viable of the proposed activated sludge modifications today for the removal of organic carbon and nutrients. In a relatively...
Cryptosporidium Removal, Occurrence, and Inactivation Methods for Wastewater
Treatment of drinking water was once considered sufficient for reducing the risk of infection from pathogenic organisms. However, as our knowledge of established and emerging pathogens in water...
Technical Approaches for Setting Site-Specific Nutrient Criteria
The purpose of this project was to develop a methodology for deriving site-specific nutrient criteria (SSNC) for surface waters, including streams and rivers, lakes and reservoirs, and coastal...
Nutrient Farming and Traditional Removal
The purpose of this study was to assess the economic feasibility of using large-scale, restored wetlands to assist publicly owned treatment works (POTWs) in meeting the U.S. Environmental...
Instrumentation, Control and Automation in Wastewater Systems
Instrumentation, control and automation (ICA) in wastewater treatment systems is now an established and recognised area of technology in the profession.
There are obvious incentives for ICA...
2nd IWA Leading-Edge on Water and Wastewater Treatment Technologies
Wastewater and drinking water treatment are essential elements of urban infrastructure. In the course of the last century there has been enormous technical development, so successful that for the...
Reduction of Pathogens, Indicator Bacteria, and Alternative Indicators by Wastewater Treatment and Reclamation Processes
In wastewater reclamation systems, microbiological monitoring is conducted to ensure that the users of reclaimed water are exposed to minimal risks from exposure to pathogens. Typically, utilities...
