Claims (9)
1. Fremgangsmåde til reduktion af tilstedeværelsen af mikroorganismer i vand under anvendelse af en energikilde og et tilsætningsstof, hvilken fremgangsmåde er kendetegnet ved, at energikilden er UV-stråling, og tilsætningsstoffet omfatter permyresyre, hvor det vand, der skal behandles, underkastes UV-stråling under og/eller efter tilsætning af tilsætningsstoffet, der indeholder permyresyre, til vandet, og permyresyren kontinuerligt tilsættes det vand, der skal desinficeres, i en mængde på 0,1 til 5 mg/l, og der foretages intermitterende øjeblikkelig chokdosering under anvendelse af permyresyre i en mængde på 10 til 50 mg/l, og en ugentlig sum af foretagne chokdoseringsperioder er 0,3-30 timer.
2. Fremgangsmåde ifølge krav 1, hvor mikroorganismerne er bakterier og/eller vira.
3. Fremgangsmåde ifølge krav 1, hvor bakterier og/eller vira er enteriske bakterier og/eller vira.
4. Fremgangsmåde ifølge krav 3, hvor bakterierne er valgt blandt Escherichia coli, Enterococcus faecalis og Enterococcus faecium.
5. Fremgangsmåde ifølge krav 2, hvor viraene er bakteriofager.
6. Fremgangsmåde ifølge krav 5, hvor bakteriofagen er MS2.
7. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 6, hvor permyresyren kontinuerligt tilsættes det vand, der skal desinficeres, i en mængde på 0,2-4 mg/l, fortrinsvis 0,3-2 mg/l og fortrinsvis 0,4-1 mg/l.
8. Fremgangsmåde ifølge et hvilket som helst af kravene 1 eller 7, hvor tilsætningen af permyresyre udføres intermitterende som en øjeblikkelig chockdosering i en mængde på 15 til 40 mg/l.
9. Anvendelse af en energikilde og et tilsætningsstof til reduktion af tilstedeværelsen af mikroorganismer i vand, hvilken anvendelse er kendetegnet ved, at energikilden er UV-stråling, og tilsætningsstoffet omfatter permyresyre, hvor det vand, der skal behandles, underkastes UV-stråling under og/eller efter tilsætning af tilsætningsstoffet, der indeholder permyresyre, til vandet, og permyresyren kontinuerligt tilsættes det vand, der skal desinficeres, i en mængde på 0,1 til 5 mg/l, og der foretages intermitterende øjeblikkelig chokdosering under anvendelse af permyresyre i en mængde på 10 til 50 mg/l, og en ugentlig sum af foretagne chokdoseringsperioder er 0,3-30 timer.
