Optimization of Reactor Startup and Nitrogen Removal of Aerobic Granular Sludge Systems

Samuel Lochmatter

Aerobic granular sludge (AGS) in sequencing batch reactors (SBR) has recently made its proofs as full-scale technology for the biological treatment of urban wastewater. In contrast to conventional flocculent activated sludge, microorganisms aggregate to de ...

Distribution of denitrifying bacterial communities in the stratified water column and sediment-water interface in two freshwater lakes and the Baltic Sea

We have studied the distribution and community composition of denitrifying bacteria in the stratified water column and at the sediment-water interface in lakes Plusee and Schohsee, and a near-shore site in the Baltic Sea in Germany. Although environmental ...

Electrochemical behavior of ammonia at Ni/Ni(OH)2 electrode

Christos Comninellis, Agnieszka Kapalka

The electrochemical oxidation of ammonia was investigated on a Ni/Ni(OH)(2) electrode prepared by potential cycling of a Ni electrode in 1 M NaClO4. It was found that oxidation of ammonia is strongly pH dependent and proceeds mainly at pH values above 7. T ...

Response of terrestrial N2O and NOx emissions to abrupt climate change

Jed Oliver Kaplan, Mirjam Pfeiffer

Being a potent greenhouse gas, N2O emitted by the terrestrial biosphere during abrupt climate change events could have amplified externally forced warming. To investigate this possibility, we tested the sensitivity of terrestrial N2O emissions to an abrupt ...
