Image of Vorticella convallaria

Description:

The heros of the process are the peritrich ciliates, like this Vorticella. Primarily through their efforts, the coliform and other suspended bacteria are filtered out of the sewage in the activated sludge tank. If the rate of throughout is increased to a rate where the growth of peritrichs is insufficient to keep up, then the ciliates are removed and the quality of the effluent plummets.
