Linking bacterial population dynamics and nutrient removal in the granular sludge biofilm ecosystem engineered for wastewater treatment

Christof Holliger, David Gregory Weissbrodt, Noam Shani

Intensive nutrient removal from wastewater in anaerobic–aerobic systems using granular sludge should rely on optimal balances at biofilm and microbial ecology levels. This study targets the impacts of reactor characteristics and fluctuations in operation c ...

Discussion of "Skimming, Nonaerated Flow on Stepped Spillways over Roller Compacted Concrete Dams" by Ines Meireles, Floriana Renna, Jorge Matos, and Fabian Bombardelli

Michael Pfister

The nonaerated region may occupy a large portion of the skimming flow in steep, stepped spillways, particularly for relatively high unit flow rates. In spite of the numerous contributions on the hydraulic properties at both the inception point of air entra ...

Synthesis factors affecting the catalytic performance and stability of Ru/C catalysts for supercritical water gasification

Christian Ludwig, Frédéric Vogel, Gaël Peng

Catalytic supercritical water gasification of isopropanol (450 degrees C, 30 MPa) over Ru/C catalysts was carried out in a fixed-bed plug flow reactor. In the absence of Ru, isopropanol decomposed to solid carbon (coke), and H-2 over the carbon support. Th ...

Assessment of bacterial and structural dynamics in aerobic granular sludge biofilms

Christof Holliger, David Gregory Weissbrodt, Yoan Rappaz

Aerobic granular sludge (AGS) is based on self-granulated flocs forming mobile biofilms with a gel-like consistence. Bacterial and structural dynamics from flocs to granules were followed in anaerobic-aerobic sequencing batch reactors (SBR) fed with synthe ...
