Nitrification test data with tap water and varying natural organic matter

Laboratory scale nitrification tests with tap water. The effect of two different NOM concentrations were tested. This data is linked to the manuscript "Decreased natural organic matter in water distribution decreases nitrite formation in non-disinfected conditions, via enhanced nitrite oxidation" by Pirjo-Liisa Rantanena, Minna M.
