Specialistkonferensen NOM 6

Vattnet i våra sjöar och vattendrag blir allt brunare. Vattnets färg har betydelse för dricksvattenproduktionen och för livet i sjön.

Den så kallade brunifieringen beror på en ökning av humusämnen (delar av djur och växter som inte har brutits ner helt) samt järn- och manganföreningar i vattnet. Orsakerna till den ökande brunifieringen tros vara en kombination av olika faktorer, däribland klimatförändringar med högre temperatur och mer nederbörd samt minskad försurning. Förändringen har observerats sedan 1990-talet och är ett internationellt problem.

Ett brunare råvatten riskerar att ge det färdiga dricksvattnet en smak av sjövatten och att minska effekten av olika desinfektionsmetoder. Dessutom kan organiskt material vara bärare av smittämnen. Framtidens råvatten kommer att kräva mer omfattande reningsprocesser och blir därmed en stor utmaning för alla VA-verksamheter.

I september 2015 arrangerades den internationella specialistkonferensen NOM 6 i Malmö med syftet att uppnå bättre förståelse av dynamiken och effekterna av NOM i akvatiska system. På konferensen presenteras den senaste forskningen om brunifiering i dricksvatten, avloppsvatten, återvunnet vatten, naturliga vatten och marina system. Över 130 vetenskapliga arbeten presenterades.

NOM 6 arrangerades av International Water Association (IWA), Lunds universitet och Sydvatten.
