The study of three WWTPs with different nitrogen removal systems during a year has provided valuable information on the characteristic protists communities present in these systems.
Population density and diversity are quite different from other wastewater systems and flagellates and amoeba besides ciliates are important members of these N-removal systems. In fact, efficient processes on N-removal, unless what it has been usually found in conventional systems, show large flagellate and amoeba populations, and these populations tend to diminish as nitrogen removal performance is moderate to low. Certain groups and genera of protist are proposed as indicative of high or low performance N-removal besides organic matter removal efficiencies. This information is a valuable step to develop predictive tools easy to use in the day to day laboratory protocols in wastewater treatment sites.
