Claims (15)
1. Fremgangsmåde til filtrering, der omfatter tilvejebringelse af et spiralvikklet membranmodul, der indbefatter en membran, der definerer modstående permeat- og retentatsider, en tilgang og en udgang, en tilførselsstrøm, der flyder aksialt fra tilgangen til udgangen langs retentatsiden af membranen, en permeatstrøm, der flyder aksialt fra tilgangen til udgangen langs permeatsiden af membranen, og en recirkulationssløjfe til tilvejebringelse af medstrømmende permeatrecirkulationstrøm til modulet; og tilpasning af strømningshastigheden af permeatstrømmen for at tilvejebringe baselinetryk ved tilgangen og udgangen på permeat- og retentatsiderne af membranen, således at forskellen i baselinetrykkene mellem permeat- og retentatsiderne af membranen i alt væsentligt er ens ved tilgangen og udgangen, hvor baselinetrykket på permeatsiden af membranen er større ved tilgangen end baselinetrykket ved udgangen og baselinetrykket på retentatsiden af membranen er større ved tilgangen end baselinetrykket ved udgangen.
2. Fremgangsmåde til filtrering ifølge krav 1, hvor modulen omfatter mindst ét strømmodstandselement på permeatsiden af membranen, hvor permeat flyder gennem strømmodstandselementet, og hvor strømningshastigheden af permeat, der flyder gennem strømmodstandselementet, er varieret for at danne den kontrollerbare trykgradient.
3. Fremgangsmåde til filtrering ifølge krav 2, endvidere omfattende periodisk tilpasning af trykket på permeatsiden af membranen for at reducere forskellen i trykkene mellem permeat- og retentatsiderne af membranen ved tilgangen og udgangen med mindst cirka 50 % i forhold til forskellen mellem basislinetryk.
4. Fremgangsmåde til filtrering ifølge krav 3, hvor den periodiske tilpasning af trykket på permeatsiden af membranen forekommer ved omtrent 1 til 30 minutters intervaller i perioder af omtrent 1 til 10 sekunder, og mellemliggende tidsperioder omfatter handlingens separationsfaser.
5. Fremgangsmåde til filtrering ifølge krav 4, hvor, når trykket er periodisk reduceret på permeatsiden af forskellen i trykkene mellem permeat- og retentatsiderne af membranen reduceres til i alt væsentligt nul ved tilgangen og udgangen.
6. Fremgangsmåde til filtrering ifølge krav 1, der endvidere omfatter periodisk udførelse af en rUTMP-proces på permeatsiden af membranen ved enten at øge permeattrykket eller mindske retentattrykket, hvilket resulterer i en kontrollerbar overtryksætning på permeatsiden af membranen i sammenligning med trykket på retentatsiden af membranen for at tilvejebringe tilbagestrømning over membranen, mens den aksiale strømning opretholdes fra tilgangen til udgangen på begge sider af membranen, hvor forskellen i trykkene mellem permeat- og retentatsiderne af membranen i alt væsentligt er ens ved tilgangen og udgangen i løbet af rUTMP-processen.
7. Fremgangsmåde til filtrering ifølge krav 2, hvor strømmodstandselementet er udvalgt fra gruppen bestående af et tilspidset enhedsindlæg, et porøst medie indeholdt i et indre rum, der er defineret af et opsamlingsrør, hvorigennem permeat flyder, en statisk blandingsanordning i et opsamlingsrør, hvorigennem permeat flyder, og mindst én baffel, der strækker sig radialt indefter fra en indre væg af et opsamlingsrør, hvorigennem permeat flyder.
8. Fremgangsmåde til filtrering ifølge krav 2, hvor strømmodstandselementet omfatter et tilspidset enhedsindlæg.
9. Fremgangsmåde til filtrering ifølge krav 2, hvor strømmodstandselementet omfatter et tilspidset enhedsindlæg indeholdt i opsamlingsrøret ved hjælp af mindst én elastisk forseglingsring, der er placeret mellem indlægget og en indvendig væg af opsamlingsrøret, og hvilket tilspidset enhedsindlæg indbefatter mindst én rille, der strækker sig under den elastiske forseglingsring for at muliggøre passage af fluid under forseglingsringen og langs en ydre overflade af det tilspidsede enhedsindlæg.
10. Fremgangsmåde til filtrering ifølge et hvilket som helst af de foregående krav, hvor membranen er udvalgt fra polyvinylidenfluorid, polysulfon eller en polyethersulfonmembran, og membranen har en porestørrelse på cirka 0,005 til cirka 5 mikrometer.
11. Fremgangsmåde til filtrering ifølge et hvilket som helst af de foregående krav, hvor tilførselsstrømmen omfatter et polypeptid, en nukleinsyre, et glucoprotein eller en biopolymer.
12. Fremgangsmåde til filtrering ifølge et hvilket som helst af de foregående krav, hvor tilførselsstrømmen omfatter et fermenteringsprodukt af en bakteriel produktionsorganisme, der er udvalgt fra gruppen bestående af Bacillus sp, Escherichia sp, Pantoea sp, Streptomyces sp og Pseudomonas sp.
13. Fremgangsmåde til filtrering ifølge et hvilket som helst af kravene 1 til 11, hvor tilførselsstrømmen omfatter et fermenteringsprodukt fra en svampefrembringende vært, hvor den svampefrembringende vært er eventuellt udvalgt fra gruppen bestående af Aspergillus sp, Trichoderma sp, Schizosaccharomyces sp, Saccharomyces sp, Fusarium sp, Humicola sp, Mucor sp, Kluyveromyces sp, Yarrowia sp, Acremonium sp, Neurospora sp, Penicillium sp, Myceliophthora sp, og Thielavia sp.
14. Fremgangsmåde til filtrering ifølge et hvilket som helst af de foregående krav, hvor tilførselsstrømmen enten omfatter en protease, og filtrering udføres ved en temperatur, der holdes på cirka
15 °C eller mindre, eller tilførselsstrømmen omfatter en amylase, og filtreringen udføres ved en temperatur, der holdes på cirka 55 °C eller mindre.
