<p>Energy-optimised water treatment assembly comprises a pre-cleaning stage, an anaerobic solid-bed reactor and a de-nitrification stage (3), in that order in the direction of flow. The pre-cleaning stage is a heated and thermally-insulated Imhoff tank with gas (11) and sludge (14) discharge points. The anaerobic solid-bed filter (2) is an anaerobic filter with a gas outlet (11) pipe. The flow of water through the solid bed (5) is upwards, the de-nitrification stage (3) is a solid-bed reactor and the flow of water through the solid bed (3) is upwards.</p> |
