Short summary
Many waterworks utilize sand filters that rely on microorganisms for water treatment. When new, these biofilters require several months for the growth of microorganisms before they become functional. This study is the most thorough documentation of this start-up process to date. Results show that the onset of removal of individual substances proceeds in a well-defined order and that the different filter depths have different functions, suggesting which activities may shorten the start-up period.
