Ballast water treatment on Alaskan coastline - Case Study
An Alaskan oil terminal had to deal with contaminated ballast water that needed to be collected and treated before discharge. They had a biological treatment process on site, but it was difficult to operate in the temperature and contaminant loading extremes the site experiences and they struggled to get it to work consistently. The plant is also required to treat spring snowmelt and rain that falls within the site boundaries, creating extremes of liquid temperatures and contaminant concentrations. QED ran...

European water policies and human health — Combining reported environmental information
Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU water legislation targeted at particular sectors: the Bathing Water Directive (BWD; EEC, 1976; EC, 2006a), the Drinking...
Pulp & Paper Water Treatment - A look at optimizing water resource management
