 Flood and drain wastewater treatment wetland study

A recent study by David Austin of North American Wetland Engineering will be published in the upcoming Volume 28 of Ecological Engineering and explores how the cation exchange capacity of an aggregate or medium effects performance in flood and drain wetland systems. The study also investigates the role of plants in flood and drain systems with different aggregate media properties. An online version of the study is available now for download at ScienceDirect by clicking on the following link: Influence of cation exchange capacity (CEC) in a tidal flow, flood and drain wastewater treatment wetland

 Design manual on small-scale wetland treatment systems

As the first publication of its kind to enable wetland design with confidence intervals, Scott Wallace P.E., Executive Vice President of North American Wetland Engineering breaks new ground with this study that incorporates data from over 1,800 small-scale wetland treatment systems. Entitled "Feasibility, Design Criteria, and O&M Requirements for Small Scale Constructed Wetland Wastewater Treatment Systems" this design manual, funded by the Water Environment Research Foundation (WERF), represents the culmination of a 3-year research project on the use, distribution, and performance of small-scale wetland treatment systems throughout the world. The report contains over 100 original figures, diagrams, and illustrations, and will be published in July 2006 by the Water Environment Research Federation and available initially to its subscribers. It will be published by IWA Publishing Limited in early fall 2006 and available to all interested parties via their website. To purchase the design manual if you are a WERF member contact the Water Environment Research Federation at www.werf.org or click here.
