  • Fluid treatment module having hollow membranes
    Patent number: 7189321
    Abstract: The invention relates to a hollow membrane (11) comprising two support layers arranged one above the other forming a space between them and a plurality of capillary tubes arranged between the support layers forming capillary channels for the flow of a first fluid, the space between the capillary tubes forming an internal cavity for the circulation of a second fluid around the capillary tubes, and the whole assembly being made of an organic polymer. These membranes (11) can be assembled into modules for the treatment of a fluid with intermediate porous panels (13).
    Type: Grant

  • Apparatus, system and method for separating liquids
    Patent number: 6613231
    Abstract: The subject of the invention is an apparatus, system and process for liquid separation by reverse osmosis, nano-, ultra- and micro-filtration under the joint action of the differential pressure built up on the either side of the membrane (22) located in the apparatus for membrane separation (1), continuous rotation of the body (15, 17, 18) in the immediate proximity to the selective layer of the said membrane, oscillation of the liquid flow, caused by the means (15, 17, 18) and induced vibration of the said membranes. The superposition of the said continuous rotary movements, liquid oscillations and membrane vibrations on each other result in the reduction of membrane clogging with the substances being retained.
