A method and apparatus (10) for the purification and/or treatment of communal and/or industrial wastewaters (11) is proposed, particularly for use in marine installations. The apparatus includes a biologically operated reaction apparatus (12) in which the wastewater (11) to be purified and/or treated is received. In the reaction apparatus (12), a biomass of high concentration is suspended. To this reaction apparatus (12), the wastewater (11) to be purified and/or treated is supplied. Subsequently, the pre-purified or, respectively, pre-treated is supplied. Subsequently, the pre-purified or, respectively, pre-treated wastewater is supplied to a membrane separation apparatus (14) in which it is separated into a permeate (150) and a retentate (160). The retentate (160) is at least partially returned to the reaction apparatus (12), whereas the permeate (150) is either discharged as useable or pure water or is returned to the reaction apparatus (12). |
