ABSTRACT:
The invention concerns a method of treating filamentous and flocculating microorganism-bearing effluent, sludge or organic substrates used in biogas installations, for reducing or avoiding the formation of bulking sludge, floating sludge and/or foam, wherein the effluent, sludge or organic substrates is or are guided in a flow passage and in the flow passage subjected to a shear loading which is sufficient to reduce the relative ratio of the number of filamentous microorganisms in relation to flocculating microorganisms. The invention further concerns an apparatus for carrying out the method.
