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 carbon-limiting algal photosynthesis. High concentrations of free CO/sub 2/ are provided through bacterial respiration which is the main contributor to algal photosynthesis. At high photosynthetic activities and low organic loadings, free CO/sub 2/ concentrations are low; its flux into algal cells determines photosynthesis and biomass production rate in the pond.
