Definitions

  • Spiral-wound membranes are known to be very susceptible to fouling due to particles, but also due to the growth of biomass, in which case one speaks of biofouling.
  • the deposited particles cause clogging in the feed spacers, while certain nutrients in the feed water may lead to the growth of biomass.
  • This biomass grows between the spacer and can cling to everything.
  • One thing and another results in the biomass being very difficult to remove by, for example, flushing.
  • Chemicals that according to the invention may be considered are: anti-sealants, base, acid, disinfecting chemicals, biocides, bactericides or oxygen-eliminating components such as, for example, bisulphite or hydrazine. After the addition of the chemicals -the flow along the membrane is stopped and the membrane is exposed to the chemicals for 1 to 10 minutes, after which the chemicals are flushed out of the membrane. It is observed that between step 2. and step 1. an extra flush of feed water may take place, while the feed flows through the membrane from top to bottom.
  • gas in the form of preferably compressed air, optionally in combination with chemicals (15), is supplied to the feed in order to aid the release of fouling components while in addition, subject to the use of suitable chemicals, bacteria, biomass and the like can be killed.
  • the O-rings (6) are used as seals between the membrane module (3) and the pressure pipe (2) in order to make it possible to reverse the direction of flow (seal for both flow directions) .
  • the vertical disposition of the pressure pipe (2) aids proper venting.
  • various pipes in the apparatus according to the invention are provided with regulating valves and shut-off valves (no reference numbers), for regulating or shutting off, respectively, the feed, perme- ate, concentrate and filtrate streams as well as the wash- water stream.
  • step 1 the flow direction through the feed spacer during production (step 1) is counter to the flow direction during flushing (step 2) .
  • the present method and apparatus are to be used in particular for the purification of liquids.

Abstract

L'invention concerne un procédé d'épuration d'eaux superficielles ou d'effluents provenant de l'épuration des eaux d'égouts. Selon l'invention, les substances flottantes, les particules solides, les bactéries, les virus et les substances dissoutes telles que le sel, les substances organiques dissoutes, les pesticides etc., sont éliminés simultanément. Pour ce faire, on fait intervenir au moins un tuyau sous pression (2) monté verticalement et doté d'une membrane (3) de nanofiltration ou d'hyperfiltration en spirale. Le flux de refoulement vers la membrane est parallèle. Le procédé de l'invention comprend les opérations suivantes :1) production de perméat et décharge simultanée et continue de concentré, et, (2) flux dans la membrane sans production simultanée de perméat. L'invention concerne également un dispositif de réalisation de ce procédé.
