For the cultivation of algae species (Chlorella vulgaris, Synechocystis salina, Phormidium foveolarum and Tribonema viride) were used media with added of wastewater from Biological Wastewater Treatment Plant in the range of 1 to 50%. For each species were set to its optimum cultivation media. The best results were obtained a fter 10-15 days of cultivation. The highest amount of biomass of the species Chlorella vulgaris was at the 5% medium (17.545 g/l), for the species Synechocystis salina peak was on average with 20% (16.556 g/l), Phormidium foveolarum – medium with added 10% (3.36 g/l), and for the species Tribonema viride – the 30% medium (2.1 g/l). Common to all species was the medium with added to 10% of the waste water, but the obtained results vary from case to case.

Keywords: algae, wastewaters, cultivation medium, biomass, optimal medium.
