Abstract
The use of solar biotechnology could prove interesting for the removal of nutrients found in domestic wastewaters. A culture of cyanobacteria, P. bohneri, was grown on synthetic and wastewater media to study the removal performance of that process, and also to look at the dynamic behaviour of nitrogen and phosphate. Eight experiments were performed during the summer of 1993 using small batch reactors of 24 liters. Each experiment lasted between two and five days. Very good removal efficiencies were observed for all pollutants (N,P). Stripping of ammonia and precipitation of phosphate were found to be very important phenomena in the removal mechanisms, i.e. between 50 and 60% of the total removal.Keywords
