Energy efficiency in waste water treatments plants: Optimization of activated sludge process coupled with anaerobic digestion

François Maréchal, Nicolas Descoins

This paper presents a study concerning the optimization of a Waste Water Treatment process. The process deals with carbon and nitrogen removal and includes activated sludge reactors coupled with an anaerobic digestion reactor. Nitrification and de-nitrific ...

Novel design of a microstructured reactor allowing fast temperature oscillations

Albert Renken, Lioubov Kiwi, Martin Luther

Two types of stainless steel microstructured reactors for catalytic gas-phase reactions have been developed and characterized with respect to their thermal behaviour under non-stationary temperature conditions. One of the reactors used (FTC-I) allowed peri ...
