ABSTRACT:
A description is given of a sewage treatment plant, in particular a small sewage treatment plant, having at least one activation tank for wastewater and/or having at least one secondary clarification tank for wastewater, wherein the activation tank and/or the secondary clarification tank are charged with shaped bodies which are freely floating in the wastewater, which is distinguished in that it has at least one filtration appliance for wastewater purification, which filtration appliance comprises at least one ceramic-based membrane for separating off microorganisms. In addition a method of purifying wastewater is described, comprising a biological purification of the wastewater by microorganisms in at least one activation tank and/or comprising a secondary clarification of the wastewater in at least one clarification tank, wherein the at least one activation tank and/or the at least one secondary clarification tank, for cleaning, is charged with shaped bodies, characterized in that the microorganisms situated in the wastewater are separated off by means of at least one ceramic-based membrane.
