V.U. Grobbelaar, C.J. Soeder and E. Stengel published a model for algal productivity and oxygen production in large scale outdoor cultures. The model accepts two input variables, temperature and incident light intensity. It assumes that algal growth and oxygen production are closely coupled and controlled by these variables. It also assumes that there are no other limiting factors. Waste water treatment systems are likely to provide adequate or excess levels of mineral nutrients. As long as residual BOD is present heterotrophic degradation, supplemented by diffusion from the atmosphere, will ensure that CO 2 deficiency will not prevent photosynthesis meeting the oxygen demand. This paper discusses the computer model, its modification and application to study algal waste treatment systems.
