Abstract: Input of active biomass into suspended-growth biological processes occurs when biological processes are in series, during bioaugmentation, and when input wastewaters contain active bacteria. This paper extends mathematical ...

Abstract: Field measurements for 466 cases of plume rise from moderately sized sources were statistically analyzed for the ability of source and plume parameters to explain variations in the apparent entrainment coefficient used in ...

Abstract: Environmental biotechnology “manages microbial communities to provide services to society.” The key services today include detoxifying contaminated water and soil to reclaim lost resources and converting diffuse energy in ...

Abstract: Siloxanes, impurities in the biogas produced from anaerobic digestion of wastewater sludges, are transformed to silica dioxide sand during combustion of the biogas, which damages the heat exchanger and engine. Decamethyl ...

Abstract: The extended steady state biofilm model is utilized to predict the performance of a completely mixed biofilm reactor in terms of substrate removal, biofilm accumulation, soluble microbial products (SMP) formation, and total ...

Abstract: A methanogenic fluidized‐bed biofilm reactor was successfully operated for the removal of 1‐μm organic colloids. The removal efficiency of total suspended solids was 72–76%, and the total chemical oxygen demand removal was ...

Abstract: Particle transport and capture are essential for the successful treatment by fluidized‐bed biofilm processes of wastewaters containing suspended organic matter. Small‐scale, once‐through, fluidized‐bed filters were utilized ...
