Theoretical considerations confirmed by outdoor experiments indicated carbon limitation of biomass production in high‐rate oxidation ponds at certain seasonal and operational conditions. Apparently, free carbon dioxide concentration in the pond is the major determinant of carbonlimiting algal photosynthesis. High concentrations of free CO 2 are provided through bacterial respiration which is the main contributor to algal photosynthesis. At high photosynthetic activities and low organic loadings, free CO 2 concentrations are low; its flux into algal cells determines photosynthesis and biomass production rate in the pond.
