Definitions

  • the present invention relates to a method and a device for controlling the integrity of microfiltration or ultrafiltration modules which are used in the separation and concentration of solutions processes and in particular in the field of water treatment.
  • FR-A-2 775 440 and WO 99/44728 provide a solution to this problem by means of a method which is based on the detection of the noise emitted by the turbulence of the fluid passing through a broken fiber. According to this prior state of the art, this method consists in
  • each module - a hydrophone mounted on the bottom drain of each module; - an amplifier of the signals delivered by this hydrophone and a comparator-analyzer ensuring the comparison of the signal-noise picked up, amplified and of a threshold noise level characteristic of an integral module, the analysis of the comparison making it possible to detect the presence possible leak on the module.
  • the invention provides a method for checking the integrity of the hollow fiber filtration modules and for detecting leaks through a totally or partially broken fiber, characterized in that it consists of :
  • said noise or sound signal is emitted, either in a frequency band different from parasitic noise, or from a higher sound pressure level.
  • the integrated modules prove to be an excellent acoustic screen and the signal detected downstream of such modules is weak, on the other hand, in the event of total or partial breakage of a fiber, the signal detected downstream is much greater.
  • the invention also relates to a device for implementing the method as defined above.
  • This device is produced in accordance with that disclosed in the prior art mentioned above, but it also comprises at least one sound transmitter for a set of modules, which emits a specific signal, either in a different frequency band parasitic noise, either from a higher power level, this or these sound emitters being positioned on the side of the modules opposite the hydrophones.
  • FIG. 1 is a schematic representation of an embodiment of the device which is the subject of the invention.
  • FIG. 1 illustrates the device in a nonlimiting exemplary embodiment in which the modules are in a filter housing from the inside to the outside of the fibers.
  • the reference 10 designates the filtration modules of the type comprising a plurality of hollow fibers grouped in bundles.
  • a hydrophone 14 has been installed on the low purge 12 of each module 10, making it possible to listen directly, in contact with clean water (permeate), to the noise of passage of the fluid.
  • a sound emitter 16 is placed on the manifold 18 for entering the liquid to be filtered (arrow L) when the operating mode is frontal, the arrow F designating the filtered liquid.
  • the sound transmitter 16 is placed on the output of the recirculation loop.
  • the arrow S designates this exit from the recirculation loop, the entry of this loop in tangential mode being designated by the arrow E.
  • hydrophones 14 fitted to each module 10 are placed on the side opposite to the transmitter 16 relative to the membrane.
  • the device may also include a programmable automaton receiving the signal emitted by managing the operation of the filtration module system, with a view to retransmitting the signal, either to a centralized system of the factory, or remotely to a operator.
  • the invention can be applied to all types of hollow fiber filtration membranes (interior-exterior or exterior-interior) and optionally to flat membranes.
  • the arrangement of the transmitters and hydrophones may be different from that described above, however it is essential that the hydrophones are not located on the same side of the membrane as the transmitter (s).
  • the detection can be done in filtration mode or in backwashing mode, or in "shutdown of the installation" mode.
  • curve A illustrates the sound level obtained on a module comprising a broken fiber
  • curve B the sound level obtained on a integral module. It can be seen that the damping of the sound signal emitted by the sound transmitter 16, by an integral membrane, is much greater than that of a module comprising at least one broken fiber.
