  • Patent number: 6780319
    Abstract: Method of purifying wastewater charged with organic matter which comprises a step of biologically treating the water, during which the organic matter contained in the water is degraded by micro-organisms thereby producing sludge, and a water-sludge separation step, the sludge coming from the separation step being recycled in the biological treatment step, this method being characterized in that it further comprises a step of degrading the sludge, coming either from the biological treatment step or from the separation step, during which the sludge is brought into contact with an ozonated gas under conditions making it possible to obtain a floc consisting of granules whose mean size is greater than 200 microns, the volatile matter content is between 50 and 65%, the thickening factor of this granular sludge, after 30 minutes of settling, always being greater than 4, the conditions for obtaining the said granular sludge consisting in: treating between 0.

  • Patent number: 6337020
    Abstract: Method for purifying waste water, whereby the waste water is subjected to a biological treatment producing sludge, part of this sludge being recycled towards the biological treatment while being subjected to ozonation combined with mechanical stirring. A mechanical stirring energy is brought in to attack the walls of the microorganisms.

  • Patent number: 6162359
    Abstract: Process for recovering and reusing effluent gas from an ozonization reactor in a plant for treating effluent, especially sewage, which includes a biological reactor, a clarifier and an ozonization reactor. The effluent gas from the ozonization reactor is brought, as a cocurrent, into contact with a stream of water containing compounds that can be oxidized by the ozone, so that the residual ozone is removed and efficiently consumed. The effluent gas thus stripped of the residual ozone is then, optionally, pressurized using a fluid taken from the plant so as to produce a gas/liquid mixture. The gas liquid mixture is converted into an emulsion of fine bubbles, and the emulsion is introduced into the biological reactor, preferably near the bottom of the latter.
