Hur mycket läkemedelsrester bryts ned i slam under lagring undersöks i projektet Reduktion av läkemedel och andra organiska miljöföroreningar under lagring/efterbehandling av avloppsslam. Ett storskaligt lagringsförsök med ca 430 ton slam fördelade på 6 olika varianter på slamlagring startade under tisdagen och onsdagen 29-30/5 på Hovgårdens avfallsanläggning i Uppsala samarbete mellan Sveriges Lantbruksuniversitet SLU, Svenska Miljöinstitutet IVL och Uppsala Vatten och Avfall AB.

What is ‘New Sanitation’ according to Professor Grietje Zeeman from Wageningen University in the Netherlands? How has the practical experience been so far with the upflow anaerobic sludge blanket (UASB) reactor for blackwater treatment and bio-flocculation of greywater? Can micropollutants be mitigated through composting of anaerobic sludge? Are heavy metals from wastewater really a problem in agriculture? Interested in learning more about how these technologies have been applied at full scale in Sneek, Venlo, Wageningen and The Hague? Click here to access Professor Zeeman’s presentation.
