1. Computerimplementeret fremgangsmåde til overvågning af funktionen afen membran til omvendt osmose i et drikkevandsforsyningssystem, hvor fremgangsmåden udføres af et computerprogram, hvor fremgangsmåden omfatter de følgende trin: at påbegynde (trin 74) en rekalibrering af membranen til omvendt osmose; at bestemme (trin 76) strømningsmængden afen forudbestemt mængde vand gennem systemet; at måle (trin 80) start-permeatledeevnen nedstrøms for membranen til omvendt osmose, efter at den forudbestemte mængde vand er strømmet gennem systemet; at beregne (step 82), under anvendelse af den målte startpermeatledeevne (trin 80), et forudbestemt totalt afvisningsforhold af opløste faststoffer og ud fra dette at beregne et tærskelværdi-udløsningspunkt, som svarer til det forudbestemte totale afvisningsforhold af opløste faststoffer, hvor beregningen af tær-skeværdi-udløsningspunktet omfatter: at måle start-permeatledeevneværdierne; at ækvivalere et gennemsnit af start-permeatledeevneværdierne til afvisningsforholdet af opløste faststoffer, og at definere gennemsnittet ved en afvisning på halvfems (90%); og at beregne tærskelværdi-udløsningspunktet ved femoghalvfjerds (75%) af gennemsnittet; at lagre (step 84) tærskelværdi-udløsningspunktet i systemets hukommelse (54); rutinemæssigt at måle (trin 86) permeatledeevnen nedstrøms for membranen til omvendt osmose, efter at den forudbestemte mængde vand er nået; at bestemme (step 90), om permeatledeevnen, som rutinemæssigt er målt i det foregående trin, ligger under tærskelværdi-udløsningspunktet; og at tilvejebringe (step 92) en indikation, efter at det er bestemt, hvornår permeatledeevnen ligger under tærskelværdi-udløsningspunktet.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at trinnet (74) med indledning sker efter en tilkoblingsrutine.
3. Fremgangsmåde ifølge krav 1, kendetegnet ved, at trinnet med indledning (74) sker, efter at membranen til omvendt osmose er blevet udskiftet.
4. Fremgangsmåde ifølge krav 3, kendetegnet ved, at trinnet med indledning (74) omfatter at sende et startrekalibreringssignal til en mi krocontroller (52) af systemet.
5. Fremgangsmåde ifølge krav 1, kendetegnet ved, at trinnet med indledning (74) omfatter en brugeraktiveret kontakt til at signalere en ændring af membranen til omvendt osmose og til at indlede en rekalibrering.
6. Fremgangsmåde ifølge krav 1, kendetegnet ved, at den forudbestemte mængde vand ligger i området af 38 -114 liter (10-30 gallon),
7. Fremgangsmåde ifølge krav 1, kendetegnet ved, at den forudbestemte mængde vand ligger i området af 56,8 liter (15 gallon).
8. Fremgangsmåde ifølge krav 1, kendetegnet ved, at trinnet med at måle vandledeevnen omfatter trinnet med at danne et gennemsnit af et område på 10-50 målinger.
9. Fremgangsmåde ifølge krav 1, kendetegnet ved, at trinnet med at måle vandledeevnen omfatter trinnet (88) med at danne et gennemsnit af 20 målinger.
10. Fremgangsmåde ifølge krav 1, kendetegnet ved, at trinnet (92) med at tilvejebringe en indikation omfatter at tænde en lysemitterende diode.
11. Fremgangsmåde ifølge krav 1, kendetegnet ved, at hukommelsen (54) er en ikke-flygtig hukommelse.
