Algae [Scenedesmus acutus and Chlamydomonas geitleri] were cultivated in the effluents from a treatment plant processing communal sewage and waste water from a large-scale hoggery. The content of N and P and the chemical and biochemical O2 demand values were estimated in the effluent before and after cultivation of algae. Removal of N and P by C. geitleri from the effluent was optimal at high effluent dilution. The removal rate of polychlorinated biphenyls (PCB) was highest at high effluent concentrations; purification efficiency in relation to PCB content depended on the algae used.
