<p>Module, for the anaerobic purificn. of waste water, contains several collection hoods in a staggered formation over the whole module cross section. These hoods collect the generated biogas which is passed into a gas collection chamber via piping (1,2). The piping is extended by a pipeline (18) bent downwards, so that a gas cushion forms in the piping to act as a block to sludge pellets which float up. The lower end of the gas inlet pipe is serrated at its edge and is surrounded by a spacer device, which can also be serrated. The gas collection chamber is open at the lower end, so that the sludge sinks back into the reactor, while no sludge can enter the gas collection chamber.</p> |
