During the research period from 2005 till 2008 to Ufa we identified 108 species and intraspecific taxa of algae and cyanoprokaryote from 71 genera, 24 orders, 11 classes and 7 division. To Beloreck (2008–2010) we identified 132 species and intraspecific taxa of algae and cyanoprokaryote from 73 genera, 42 families, 26 orders, 9 classes and 7 division. The coefficient of community species composition showed distinct cyanoprokariote algal cenoses (CPAC) aerotank. Comparison of the taxonomic structure CPAC by department showed similarities CPAC Beloretsk activated sludge treatment facilities with the city of Ufa. In Beloretsk in the aerotank there is a greater diversity of algae due to Bacillariophyta. Our studies indicate that the selection bioestimatorov is a good instructional techniques in the analysis of the status of wastewater treatment facilities.
