Special Issue of Water Environment Research Features Two State-of-the Art Reviews and Ten Articles on Biological Treatment for Wastewater 
Read about Issues and Solutions in March 2014 Issue  
 
ALEXANDRIA, Va. – The Water Environment Federation (WEF) has issued the first of two special editions of Water Environment Research (WER). The March 2014 issue of WEF's international peer-reviewed journal includes two state-of-the art reviews and ten articles on biological treatment, including one that is available through the publication’s free open-access program. The second special edition is planned for the September 2014 issue.
 
The first of the two reviews, “Simultaneous Biological Nutrient Removal: A State-of-the-Art Review” by Glen T. Daigger and Helen X. Littleton, adds to the knowledge base about biological nutrient removal (BNR) by using tools such as computational fluid dynamics to describe situations where existing flow patterns lead to fluctuating dissolved oxygen concentrations. According to WER Editor-in-Chief Tim Ellis, who wrote a special BNR editorial for the issue, “these conditions can contribute to simultaneous biological nutrient removal (SBNR). In fact, the floc structure itself can lead to internal DO gradients sufficient to facilitate SBNR.” 
 
In another review paper, subscribed readers will enjoy an update on the latest research regarding soluble microbial products (SMP) and, in particular, their relationship to extra polymeric substances. With the increasing reliance upon membrane bioreactors, the accumulation of SMP at long sludge ages has implications for membrane design and operation, particularly with regard to membrane fouling. The influence of SMP in drinking water biotreatment is also reviewed.
 
Formerly available to subscribers only, selected WER articles are available free to the public on a monthly basis through an open-access program. Click here to download the open access article, “Simultaneous Biological Nutrient Removal: A State-of-the-Art Review” by Glen T. Daigger and Helen X. Littleton.
 
Published since 1928, WER features peer-reviewed research papers and research notes, as well as state-of-the-art and critical reviews on original, fundamental, and applied research in all scientific and technical areas related to water quality, pollution control, and management. Originally known as the Sewage Works JournalWER is available in both print and online formats and receives approximately 300 new research submissions each year.
