Abstract:

The present study was conducted in a full-scale activated-sludge plant to evaluate the influence of detergent concentration on the development of ciliated protozoa during the biological treatment of wastewater. Density and diversity of ciliates were determined in relation to detergents entering the aeration tanks. Results suggest that a threshold of detergent concentration in wastewater entering the aeration tanks for an efficient biological process is 10 mg L^-1. Values higher than this, yield a significant decrease in ciliate populations. © 1992 Kluwer Academic Publishers.
