Fig. 3. (a) Reduced fecal coliform concentrations, (b) reduced turbidity of the effluent, and (c) relationship between the two reduced values. Different symbols are used to distinguish among replications. The linear regression line is shown in the Part c; the regression equation is Y = (0.994 ± 0.039) X + (0.003 ± 0.042), R2 = 0.807.
