In >100 years, sand filtration has been the heart of Danish drinking water treatment. Typically, aeration followed by sand filtration is adequate to remove Fe, NH4+, and Mn without the use of coagulants. The resulting drinking water is generally free of pathogens and biologically stable, making it possible to produce drinking water without any form of disinfection. In this project, analysis of microbial communities in sand filters combined with sophisticated water and filter medium sampling through filter depth has increased the understanding of physico-chemical and biological processes. Microbiological diversity and abundance are coupled with removal rates of Fe, NH4+, and Mn through the entire active depth of 10 full-scale sand filters.
