Abstract
Extensive biological analysis of raw and biologically treated wastewater demonstrated the presence of yeasts, acid fast, staphylococci and total coliform grganisms, in all tested samples, reached average values of 5.6x10°, 1.3x10', 1.9x10' and 1.4x10' respectively in raw, wastewater. These figures are reduced to 5.6x10°, 2.1x10, 4.3x109 and 3.6x10' during biological treatment and primary sedimantation. The relative resistance of these organisms to chlorination was found to be: acid-fast >yeast > staphylococci > coliforms. Acid-fast, yeast or staphy lococci organisms can represent a valid indicator of chlorination efficiency rather than coliforms.
