Abstract

In order to purify industrial effluent, in particular effluent produced in cleaning vehicles, it is proposed that the effluent should be received in a receiving chamber (2) and harmful pollutants such as hydrocarbons broken down aerobically by micro-organisms. To that end, use is made of a submergible fixed-bed unit (4) to which a biofilm or "lawn" of micro-organisms adheres. The fixed bed (4) is formed by the surface of carrier particles (20) of synthetic waste material which are held together in a cage (21). At least 50 % of the interior space of the cage is accounted for by free space between carrier particles (20). Flushing operations flush dead micro-organisms and other solids from the cage (21), thereby ensuring that the free spaces do not become choked and that the biological filter has a long operating life. This considerably enhances the activity of the bioculture by preventing the formation of dead or otherwise damaging material, thereby allowing the harmful pollutants led through the device to react continuously.
