The effects of acetate concentrations on competition between microbial populations in enhanced biological phosphorus removal from wastewater

Tu, Yunjie

Enhanced biological phosphorus removal (EBPR) is a popular modification of the activated sludge process, and has been studied and applied for decades. It was hypothesized that the bacteria responsible for EBPR, polyphosphate accumulating organisms (PAOs), have an advantage over their competitors, …

Phosphorus Retention and Fractionation in Masonry Sand and Light Weight Expanded Shale Used as Substrate in a Subsurface Flow Wetland

Forbes, Margaret G.University of North Texas2002

… technology for long-term phosphorus (P) removal. The P retention effectiveness of subsurface wetlands can be improved by using appropriate substrates. The objectives of this study were to: (i) use sorption isotherms to estimate the P sorption capacity of the two materials, masonry sand …
