Abstract

The invention relates to an installation for the biological treatment of water, said installation comprising supply means (1) for supplying the water to be treated, supply means (40) for supplying sludge from at least one downstream clarifier, said sludge supplying the purifying biomass, at least one upstream tank (3), at least two channel tanks (2a, 2b, 2c, 2d) provided with aeration means, and means (5) for discharging a mixed liquor comprising the treated water and the purifying biomass towards said clarifier. The inventive installation is characterised in that it has an essentially circular configuration according to which the upstream tank (3) occupies the central position and the channel tanks (2a, 2b, 2c, 2d) have a curved form and occupy a peripheral position around said upstream tank.
