Abstract: Procédé de contrôle de l'intégrité des modules de filtration à fibres creuse s et de détection de fuites au travers d'une fibre totalement ou partiellement cassée, caractérisé en ce qu'il consiste à: - émettre un bruit ou signal sonore au moyen d'un émetteur situé d'un côté des membranes des modules de filtration; - détecter, de l'autre côté des membranes, le bruit ou signal sonore émergent d'une fibre rompue, que ladite fibre soit ou non soumise à u ne circulation de fluide; - amplifier le signal-bruit ainsi obtenu et - compare r le signal amplifié résultant à un niveau du bruit-seuil, dans la même gamme de fréquences.

Abstract: Improved reactor for the biological treatment of sewage, intended to replace the aeration tank in plants comprising an anaerobic tank in which denitrification takes place, an anaeration tank where the nitrification of the effluents by aerobic bacteria is carried out and a final clarifier, which comprises a single tank having three separate zones which are, in the order in which the liquid to be treated passes through them successively: an aeration operating with plug flow; an anaerobic zone; and a completely mixed zone comprising means permitting it to operate under adjustable aeration conditions.

Abstract: Device intended for removing washing water from filters containing granular filter material, which are washed simultaneously with water and air, such as those employed especially in water treatment, and for recovering the particles of granular filter material which are entrained by the water during the washing, characterised in that it comprises: - a calibrated member (11) for collecting and removing dirty water; - internal and external partitions (10,10a - 20,20a) placed on either side of the collecting member, defining inside the internal partitions a water recovery region and, between the internal and external partitions, flow-calming regions promoting the separation, by downward concurrent settling, of the particles of granular material and of the dirty water to be removed, - a baffle (13) intended to prevent the preceding regions being perturbed by the three-phase water-air-granular material mixture formed during the washing, placed under the said regions and directing this mixture towards an external degassing region, where the air is removed before the mixture, having become two-phase, enters the calming/settling regions.

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: Dispositif destiné à effectuer l'évacuation de l'eau de lavage des filtres à matériau filtrant granulaire, lavés simultanément à l'eau et à l'air, tels que ceux utilisés notamment dans le traitement de l'eau, et la récupération des particules de matériau filtrant granulaire entraînées par l'eau pendant le lavage, caractérisé en ce qu'il comporte : - un organe calibré (11) de collecte et d'évacuation de l'eau sale ; - des cloisons internes et externes (10,10a - 20,20a) placées de part et d'autre de l'organe de collecte, délimitant à l'intérieur des cloisons internes une zone de récupération de l'eau, et, entre les cloisons internes et externes, des zones de tranquillisation de l'écoulement favorisant la séparation, par décantation à co-courant descendant, des particules de matériau granulaire et de l'eau sale à évacuer, - un déflecteur (13) destiné à éviter la perturbation des zones précédentes par le mélange triphasique eau - air - matériau granulaire formé au cours du lavage, placé sous lesdites zones et orientant ce mélangE vers une zone de dégazage extérieure, où l'air est évacué avant que le mélange, devenu diphasique, entre dans les zones de tranquillisation/décantation.

Abstract: Appareil pour le mélange rapide "en ligne" de deux fluides : un fluide primaire (A) et un fluide (B) caractérise en ce qu'il comporte au moins une buse (3) d'injection d'un fluide secondaire constitué par un mélange (kA + B) d'une fraction(k) du fluide primaire (A) et du fluide (B) ou par le seul fluide (B), cette buse étant disposée dans la tuyauterie (1) dans laquelle s'écoule le fluide primaire (A) et munie d'un diaphragme (4) agencé et dimensionné de telle sorte qu'il se crée, à la sortie de la buse, un courant fluide (6) orienté radialement, permettant le mélange rapide des deux fluides dans une zone de dimensions très réduites.
