Claims (7)

1. Fremgangsmåde til rensning af drikkevand, hvorved drikkevandet først ledes via et ionbyttermateriale (4), som omfatter sølv og har en antibakteriel virkning, og efterfølgende et middel til sølvfjernelse (15), hvorved der i forbindelse med midlet til sølvfjernelse (15) anvendes et fiberformet tildannet modificeret po-lyacrylat, som mindst omfatter en svovlholdig funktionel gruppe til kompleksering af sølvet, og hvorved sølvet fjernes både i ionisk og i homopolær form.
2. Fremgangsmåde ifølge det foregående krav, hvorved der anvendes et middel til sølvfjernelsen (15), der som aktiv gruppe til kompleksering af sølv indeholder svovlholdige funktionelle grupper thioamid og/eller aminothiol.
3. Fremgangsmåde til rensning af drikkevand ifølge et af de foregående krav, kendetegnet ved, at inden for området af ionbyttermaterialet (4) tilføres drikkevandet over 200 ppb sølv, og ved hjælp af midlet til sølvfjernelsen reduceres sølvkoncentrationen til under 80 ppb.
4. Fremgangsmåde til rensning af drikkevand ifølge et af de foregående krav, hvorved de svovlholdige funktionelle grupper er en funktionel gruppe, ved hvilken svovl er bundet til et carbonatom, som omfatter en aminogruppe.
5. Fremgangsmåde til rensning af drikkevand ifølge det foregående krav, hvorved den svovlholdige funktionelle gruppe er en thioamid eller en 1 -aminothiol.
6. Fremgangsmåde til rensning af drikkevand ifølge et af de foregående krav, hvorved der som middel til sølvfjernelsen anvendes et ikke-vævet stof (6), som har en fibertykkelse på 10 til 20 mikrometer.
7. Fremgangsmåde til rensning af drikkevand ifølge ethvert af de foregående krav, hvorved det filtrerede drikkevands sølvkoncentration er mindre end 100 mi-krogram/l, fortrinsvis mindre end 80 mikrogram/l og især fortrinsvis mindre end 50 mikrogram/l.
