In the context of the EU Project LIFE+ ENV/IT/075-BIOSUR (Rotating bioreactors for hydrogen sulphide sustainable removal), a full scale prototype of a Rotating Bed Biofilm Reactor was designed and constructed with the aim of using the biodiscs rotation as innovative strategy for excess biomass removal. The prototype was tested for more than one year and the Removal Efficiency was in average 80% and inlet H2S concentration reach up to 1 g S m-3.

Abstract
In the context of the EU Project LIFE+ ENV/IT/075-BIOSUR (Rotating bioreactors for hydrogen sulphide sustainable removal), a full scale prototype of a Rotating Bed Biofilm Reactor was designed and constructed with the aim of using the biodiscs rotation as innovative strategy for excess biomass removal. The prototype was tested for more than one year and the Removal Efficiency was in average 80% and inlet H2S concentration reach up to 1 g S m-3. The data collected during the test phase were used to simulate the process with a simple model implemented in Aquasim. Some parameters where taken from literature, other from previous tests with the same biomass and others, such as the Sludge Retention Time, estimated with the model. The model shows different removal efficiency in each sector of the prototype.
