Operating a two-stage microbial fuel cell–constructed wetland for fuller wastewater treatment and more efficient electricity generation
By integrating microbial fuel cells (MFCs) into constructed wetlands (CWs) the need and cost of building a reactor are eliminated, while CWs provide the simultaneous redox conditions required for optimum MFC performance. Two single-stage MFC-CWs, with dewatered alum sludge cake as the main wetland medium for enhanced phosphorus removal, were operated to determine the effects of electrode ...

Alum application to improve water quality in a municipal wastewater treatment wetland
Received for publication January 18, 2008. Nutrient removal in treatment wetlands declines during winter months due to temperature. A 3-mo (wintertime) mesocosm study was conducted to determine the effectiveness of alum in immobilizing P as well as other nutrients during this period of reduced treatment efficiency. Eighteen mesocosms, triplicate alum, and three controls or no alum were ...

New Study Links Septic Tanks to Florida Algal Blooms
State seeks millions to help residents disconnect from septic systems and connect to sewers In 2004, the first major toxic green algal blooms were noted on Florida’s tourism-reliant coastlines. Less than a decade later, the blooms earned the summer of 2013 the title “Toxic Summer.” By the summer of 2016, the toxic blooms covered more than 30 square miles of Florida’s ...
