There is conflicting evidence concerning the negative effects of high concentrations of dissolved oxygen on nitrifying bacteria. This project was developed to determine what happens to an established slime layer in a fixed-film, flow-through bio-filter, exposed to oxygen supersaturation. Specific objectives were to determine qualitatively and quantitatively whether the treatment is actually beneficial after acclimation, and whether rapid fluctuations in DO are detrimental to an acclimated culture.
