Abstract: A reactor for enzymatic degradation of biological sludge at elevated temperature, is new. A reactor (1) designed to treat biological sludge by enzymatic degradation, employs a physical agitation system (5, 6) to inject gas into the effluent and an independent regulator (8) to control oxygen input according to the specific needs of the biomass to ensure degradation of the residual organic materials. At the top of the reactor there is a probe (10) to measure the oxygen content, linked to the regulator (8), and a second probe (12) to measure gas pressure, connected to a recycling circuit (16). A heat exchange circuit (2, 3) ensures that effluent entering the reactor is heated after being initially thickened, and the effluent feed circuit incorporates an additional heat exchanger (17) fed by heating steam to be used during starting and booster phases.

Abstract: A hollow fibre (10) filter module test procedure transmits (16) sound during normal, stopped or back flushing operational mode, from one side of the filter module membrane in a different band or at a higher level to parasitic noises and detects (14) it emerging from a broken fibre on the other side for comparison with a threshold in the same frequency band. An Independent claim is also included for equipment using the procedure.

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.
