Abstract: Liquid effluent treatment module comprising at least one tank portion suitable for receiving a plurality of packing elements that may receive a biological material, the tank portion defining a horizontal longitudinal axis and comprising at least one effluent feed, characterized in that the tank portion further comprises: ∘at least one line for collecting treated effluent arranged in a central part of the tank portion and parallel to the horizontal longitudinal axis, ∘at least one air injection line arranged in a lower part of the tank portion, off-centered and parallel to the line for collecting treated effluent so as to give rise to a spiral movement of the liquid effluents.

Abstract: Device for treating aqueous effluents comprising:



A tank,
A rotary filter arranged in the tank to carry out an aqueous effluent filtration operation,
At least one UV lamp disposed in the tank so as to be immersed in the filtered aqueous effluent,
At least one catalyst element arranged to be illuminated by the UV lamp and fixed in the tank so as to be immersed in the aqueous effluents and/or fixed on the rotary filter.

Abstract: Method for treating aqueous effluents, comprising the following steps: a) simultaneously feeding the aqueous effluents into at least two basins comprising at least one upstream basin and at least one intermediate basin in the flow direction of the aqueous effluents, the basins being in fluid connection and in series with one another; b) biologically treating, in a fluid bed, the aqueous effluents to be treated in the at least two basins; c) transferring at least one portion of the biologically treated aqueous effluents to a de-aerator; d) de-aerating the biologically treated aqueous effluents in the de-aerator; e) recirculating at least one portion of the de-aerated aqueous effluents to at least the upstream basin and preferably the at least two basins.
