Effect of Landfill Leachate Pretreatment and SBR Operational Parameters on Nitrification Efficiency and Activated Sludge Microbial Populations

Creator:

Miller, Kierstin M.

Abstract:

A year-long, bench-scale treatability study was performed to assess whether an activated sludge sequencing batch reactor could be used to treat an influent stream of 50/50 (v/v) municipal wastewater and landfill leachate to discharge standards established by the Oregon Department of Environmental Quality. One primary obstacle that was exposed during...

Determination of equilibrium partial pressure of ammonia gas above anaerobically digested sewage sludge

Creator:

English, Charles Joseph

Abstract:

A laboratory study of anaerobically digested sewage sludge was performed to measure equilibrium constants for ammonia in the sludge. Measured constants describing the solution and dissociation of ammonia in sludge were compared to theoretical constants obtained from thermodynamic data. No significant difference was found between these two sets of constants....
