  • Submerged membrane filters are generally divided into two types - curtain-type filters and pillar-type filters.
  • One of the common features of these filters is that both ends of the hollow fiber or capillary membranes are potted together.
  • the top ends of the membranes are potted together and the bottom ends of the membranes are potted together.
  • the air scouring effects near the potted ends are relatively poor, and solids often deposit near the potted ends of the membranes and reduce the effectiveness of the filter.
  • US Patent Application No. 2004/0035779A1 discloses a vertically placed straw-type membrane filter with the bottom of the hollow fiber membranes or capillary membranes and the water collecting chamber at the bottom being cast together.
  • descending solids have a tendency to deposit at the bottoms of the hollow fiber membranes or capillary membranes gradually polluting the membranes upward from the bottom ends of the membranes.
  • the hollow fiber membranes or capillary membranes are submerged in the filtered liquid in an open manner.
  • the liquid near the membrane surface can be stirred by means of cascading air, the kinetic energy of liquid flow on the membrane surfaces is relatively low, and this results in a higher concentration of pollutants on the membrane surfaces, contamination of the membranes, and a reduction of filtration flux per unit area of the membranes.
  • US Patent No. 7,179,370 discloses adding plates around an assembly of membrane filters to form a membrane case.
  • the membrane case formed by the plates has an open top and an open bottom. Cascading air at the bottom ends of the membranes creates an air-lift effect that causes the air-liquid mixture to flow upward inside the membrane case and to flow downward outside the membrane case in order to achieve liquid scouring of the membrane surfaces.

  • Both US Patent No. 7,179,370 B2 and Chinese Patent Application No. 200610113851.2 disclose pillar-type membrane filters with potted bottom ends. However, the air-liquid flow generated by the air-lift effect is not able to scour the bottom portion of the membrane fibers or capillaries, and this results in membrane fouling that gradually develops upward.
  • Some embodiments of the invention provide a membrane filter including a collecting chamber and a plurality of membranes.
  • Each of the membranes includes a sealed free end, a tube cavity, and an open potted end.
  • the open potted end is in fluid communication with the collecting chamber.
  • the sealed free end is allowed to move laterally substantially freely, causing solids on external walls of the membranes to fall by gravitational force to a bottom portion of a reservoir, and to be drained out of the system.
  • Some embodiments of the invention provide a shell around the membranes. Unfiltered water can be directed to flow around the membranes so that the surface of the membrane is scrubbed by water.
  • Some embodiments of the invention include an enclosure around the membranes that makes pressurized filtration possible.
  • Embodiments of the invention provide a method of filtering water.
  • the method can include suspending membranes in unfiltered water and allowing sealed free ends of the membranes to move laterally substantially freely.
  • the method can also include directing unfiltered water flow toward the open potted ends and around the membranes to scrub the membranes.

Abstract

L'invention se rapporte à un procédé de filtration de l'eau et à un filtre à membrane (100). Le filtre (100) inclut une chambre collectrice (120) et plusieurs membranes (110). Chaque membrane (110) inclut une extrémité libre hermétiquement fermée (111), une cavité tubulaire et une extrémité empotée ouverte (112). L'extrémité empotée ouverte (112) est en communication fluidique avec la chambre collectrice (120). L'extrémité libre hermétiquement fermée (111) peut se déplacer sensiblement librement sur le côté, ce qui fait tomber les matières solides sur les parois externes des diverses membranes (110) sous l'effet de la pesanteur jusqu'à une partie inférieure d'un réservoir et devant être évacuées hors du système. L'eau non filtrée peut être dirigée vers les extrémités empotées ouvertes (112) pour laver les membranes (110) avec de l'eau non filtrée sans emmêler les membranes (110).
