🧪 Biofilter Kinetics (DO Depletion Rate, Full Nitrification NH3-N <0.1 mg/L, Heterotrophs)

Biofilter Dissolved Oxygen & Nitrification Calculator

Model stoichiometry of biological oxygen consumption ($4.57 ext{ mg O}_2 ext{ per mg NH}_3 ext{-N oxidised}$) inside drinking water biofilters: calculate dissolved oxygen ($DO$) depletion through deep carbon/sand beds, guarantee complete nitrification ($NH_3 ext{-N} < 0.10 ext{ mg/L}$), prevent anaerobic bed conditions, and process yields.
