<p>An apparatus for producing biogas includes a fermenting tank (1) with conveying members for removal of surface scum and/or sediment. A downwardly extending baffle wall (15) has its lowest edge immersed in the scum and a first conveying member (16) moves across that wall and downwardly into the top of the scum, carrying scum to below the wall and pushing it toward the outlet (7). A second conveyor (16a) scoops sediment and lifts it to the outlet where it is dumped. <IMAGE></p> |
