Decentralised Water and Wastewater Systems
The World Health Organization estimates that globally one billion people are without access to safe water and two billion people without adequate sanitation. The health...
Biological Nitrogen Removal Activated Sludge Process in Warm Climates
Many Biological Nitrogen Removal (BNR) activated sludge processes in warm climates are conservatively designed, because little systematic investigation has been carried out on the BNR activated...
DayWater: an Adaptive Decision Support System for Urban Stormwater Management
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...
Innovation in Dewatering Sludges
This report will only be available as a Pay-Per-View item.
Dewatering practices reduce the water content of sludges in order to minimise the volume to be handled and improve handling...
Guidelines for the Identification of Ciliates in Wastewater Treatment Plants
Ciliated protozoa are one of the most relevant biological communities in the reactors of wastewater treatment plants. These organisms are excellent tools to assess the biological...

Promoting Equitable Consideration of Decentralized Wastewater Options: Research Digest
This study, managed by the Water Environment Research Foundation (WERF) and funded by the U.S. EPA, identified the principal barriers that prevent engineers from...
An Economic Framework for Evaluating the Benefits and Costs of Biosolids Management Options
Agencies responsible for wastewater treatment have choices regarding how they manage their treatment process residuals. They can consider them waste products requiring suitable disposal (e.g.,...
Membrane Bioreactors
Membrane Bioreactors (MBR) are becoming increasingly important in the treatment of municipal wastewater. Compared to traditional treatment techniques, MBR’s require far smaller...
