Summary
The composition of algal flora and the periodicity of algae in raw and stabilized sewage have been investigated. 36 genera and 70 species of algae are reported.
Members of Cyanophyta and Euglenophyta predominate in raw sewage, and there is little variation in the algal flora in different seasons.
There is a marked and rapid change in the algal flora of stabilized sewage as compared to raw sewage. Members of Chlorococcales ultimately become dominant in stabilized sewage.
