Abstract

The present method provides a solution on problems in connection with nitrogen generation in or gas supply to a continuously operating granular filter in a biological process during processing water. The solution is that the biological process is carried out in the filter bed and that the filter medium (1) is transported from the bottom of the filter bed to the upper surface thereof, however with the essential difference that the filter medium (1) is not subjected to any washing in connection with this transport (2) and altogether not at all. The water from the transport is instead mixed with the water passed through and processed in the filter bed and are discharged together, eventually to a succeeding treatment step.
