Denitrifying Bioreactors for Nitrate Removal: A Meta-Analysis.
Meta-analysis approaches were used in this first quantitative synthesis of denitrifying woodchip bioreactors. Nitrate removal across environmental and design conditions was assessed from 26 published studies, representing 57 separate bioreactor units (i.e., walls, beds, and laboratory columns). Effect size calculations weighted the data based on variance and number of measurements for each bior...

15 صفحه اولTemperature and Substrate Control Woodchip Bioreactor Performance in Reducing Tile Nitrate Loads in East-Central Illinois.
Tile drainage is the major source of nitrate in the upper Midwest, and end-of-tile removal techniques such as wood chip bioreactors have been installed that allow current farming practices to continue, with nitrate removed through denitrification. There have been few multiyear studies of bioreactors examining controls on nitrate removal rates. We evaluated the nitrate removal performance of two...
متن کاملEnhanced Biological Phosphorus Removal within Membrane Bioreactors
Several Membrane Bioreactor (MBR) facilities have been constructed with the intent of providing Enhanced Biological Phosphorus Removal (EBPR), and several additional such plants are being designed and constructed. Full-scale plant information is now available for process designers to better understand the unique design and operating issues associated with the incorporation of EBPR designs in MB...
متن کاملRemoval of Carbon and Nitrogen Compounds in Hybrid Bioreactors
Both types of biomass, despite some similarities, show also many differences. Probably as a result of complex relations (competition, migration, physical factors like flow velocity and biochemical factors like oxygen supply) the flocs and attached biomass can demonstrate many differences, e.g. texture, active surface, heterotrophs and autotrophs ratio, and especially biomass age. A compilation ...
