The invention relates to an apparatus for the restoration or rehabilitation of stagnant waters, such as lakes, ponds or the like. In order to eliminate oxygen deficits, in particular of the lowest water layer, to exclude whirling up sediments and impairing the flow behaviour, the apparatus is provided with a support plate (2) having at least one reaction tube (4) connecting the bottom, ending at a distance above the bottom of the water body and furnished with an upper intake orifice (5), is provided with a conveyor shaft (9) arranged in the reaction tube (4) and with at least one distributor pipe (14) arranged radially at the bottom of the reaction tube (4) and furnished with outlet orifices (15). <IMAGE>
