The aim of this paper was to propose a granulation mechanism in order to interpret all the experimental observations that arose during experiments on two UASB reactors, where one was supplemented with ferrous iron at a dose of 0.01 g Fe2+ per g COD feed. This supplementation with ferrous iron allowed COD removal of more than 98% at a loading rate of 9 g COD/L per day, which was 24% higher than for the reactor not receiving the ferrous iron. Moreover, in the Fe2+-dosed reactor, a higher increase of the granule diameter was observed. Indeed, the granule diameter in the Fe2+-dosed reactor at the end of the experiments was 56% greater than that of the control reactor, This mechanism describes the course of anaerobic granule growth. The formation of the inorganic precipitate of ferrous sulphide constitutes the inert nuclei around which the biomass is attached. This initiates the formation of new granules. (C) 2008 Elsevier Ltd.
