    Abstract: L'appareil est constitué par une cuve dont la partie supérieure à la forme d'un parallélépipède rectangle et la partie inférieure celle d'une pyramide tronquée renversée, cette cuve étant divisée intérieurement en trois compartiments, juxtaposés, et communiquant entre eux par leur base et dans lesquels l'eau à traiter subit successivement les traitements physico-chimiques nécessaires à son épuration, des plaques avec déflecteurs et des tubes parallèles inclinés étant disposés respectivement dans le deuxième et le troisième compartiment de l'appareil, l'inclinaison de ces plaques et tubes déterminant celle des parois extérieures de l'appareil, dans la partie pyramidale, ainsi que celle des parois internes de séparation des trois compartiments.

    Abstract: Reactor for oxidation and biological reduction of liquid to be treated by upward circulation and recirculation, comprising, in a vertical lengthwise enclosure (5) accessible by an entry (9), a lower biomass fixation layer (1) made of a material with a density lower than that of the liquid and an upper biomass fixation layer (3) made of a material with a density higher than that of the liquid, characterised in that the lower layer (1) is separated from the upper layer (3) by a transverse partition (2) forbidding the passage of the filtering materials between a lower zone situated under the partition (2) and an upper zone above the partition (2), a delivery of oxidising gas (8) provided under the upper layer (3) and above the partition (2), an output (10) of the treated liquid and recycled by a pump (12) and external piping (11) to the entry (9). … …

    Abstract: A device designed for being adapted to surround a duct formed with one or several orifices operable for feeding a fluid to an apparatus, such as a reactor, used for the treatment of liquids, notably water, and including a resiliently deformable membrane, also formed with one or several orifices communicating with that or those of the fluid feeding duct, characterized in that it is made of two half shells threaded and clamped onto the fluid inlet duct, one of which having a housing for the resiliently deformable membrane and an orifice for the distribution of the fluid to the apparatus.

    Abstract: The parent patent deals with the continuous extn. of sludge from the surface of a rectangular flotation tank by means of a moving bridge with a horizontal drum fitted with suitable blades. In addition the sludge is simultaneously extracted from points at the bottom of the tank by means of a suction arm. The bridge moves on four wheels. A drum consists of an axle carrying two circular end-plates which have necks which support the assembly and rest on pulleys mounted on the bridge. The drum is fitted with blades and acts on the sludge at the surface. The bridge includes two suction arms, the object of the addition, which consists of tubes in the form of an inverted "T" with the horizontal portion, at the base of the tank. The sludge can be drawn up through holes by pumps and pumped along pipe to the receiving device for the surface sludge. The sludge can be pumped while the bridge is moving in both directions; the surface and the base sludges can be extracted simultaneously so that the efficiency of the appts. described in the parent patent is thus improved.
