For single-sludge denitrification systems, modelling of anoxic reactors currently uses the kinetics of aerobic heterotrophic growth together with a correction factor for anoxic conditions. This coefficient is computed on the basis of respirometric measurements with the assumption that the heterotrophic yield remains the same under aerobic and anoxic coditions. The paper provides the conceptual proof that the yield coefficient is significantly lower for the anoxic growth on the basis of the energetics of the related metabolic processes. This is used for the interpretation of the very high values for the correction factor experimentally determined for a number of industrial wastewaters. A default value for the anoxic heterotrophic yield coefficient is calculated for domestic sewage and compatible wastewaters and proposed for similar evaluations.

Acclimatization to altitude often results in a rightward shift of the O2 dissociation curve (ODC). However, a left-shifted ODC is reported to increase exercise tolerance in humans at medium altitude and increase survival in rats breathing hypoxic gas mixtures. We examined this paradox using a computer model of pulmonary gas exchange. A Bohr integration procedure allowed for alveolar-capillary diffusion. When diffusion equilibration was complete, mixed venous (PVO2) and arterial PO2 fell as O2 consumption (VO2) was increased, but PVO2 approached a plateau. Under these conditions a right-shifted ODC is advantageous (higher PVO2) at all but very high altitudes. However, diffusion limitation of O2 transfer may occur at any altitude if VO2 is increased sufficiently. If this occurs, a left-shifted ODC results in higher calculated VO2max (compared with the standard ODC). Further, diffusion limitation always occurs at a lower VO2 with a right-shifted ODC than with a left-shifted ODC. We conclude that whether a leftward or rightward shift in the ODC is advantageous to gas exchange at altitude depends on the presence or absence of diffusion limitation.
