Denitrification of agricultural drainage line water via immobilized denitrification sludge.
Nonpoint source nitrogen is recognized as a significant water pollutant worldwide. One of the major contributors is agricultural drainage line water. A potential method of reducing this nitrogen discharge to water bodies is the use of immobilized denitrifying sludge (IDS). Our objectives were to (1) produce an effective IDS, (2) determine the IDS reaction kinetics in laboratory column bioreacto...

متن کاملDenitrification in the Riverstrahler Model
Riverstrahler is a process-based model of nutrient transfer and biogeochemical functioning of large river systems (Billen et al., 1994; Garnier et al, 1995; Billen & Garnier, 2000) at the seasonal scale. Its essence lies in the coupling of an original representation of the drainage network, partly based on the streamorder classification of Strahler (1957), with a detailed model of biogeochemica...
متن کاملRemoval of highly elevated nitrate from drinking water by pH-heterogenized heterotrophic denitrification facilitated with ferrous sulfide-based autotrophic denitrification.
The performance of acetic acid-supported pH-heterogenized heterotrophic denitrification (HD) facilitated with ferrous sulfide-based autotrophic denitrification (AD) was investigated in upflow activated carbon-packed column reactors for reliable removal of highly elevated nitrate (42 mg NO(3)-Nl(-1)) in drinking water. The use of acetic acid as substrate provided sufficient internal carbon dioxi...
