<p>The invention relates to an effluent treatment plant and to a method for treating effluent. The plant comprises a pair of elongate vessels (5, 12), one vessel (12) being for aerobic and the other (5) being for anoxic metabolisation of effluent by microorganisms, each vessel having a downcomer zone (4, 11) and a riser zone (7, 14). The first riser zone (7) of the vessel (5) for anoxic metabolisation communicates with the downcomer zone (11) of the vessel (12) for aerobic metabolisation.</p> |
