Figure 2. Relationship between coagulant dose, pH, and turbidity removal. Figure obtained with Figure 2. Relationship between coagulant dose, pH, and turbidity removal. Figure obtained with the mean removal scores of three replicates for each pH level and dose, n = 3. The error bars repre- the mean removal scores of three replicates for each pH level and dose, n = 3. The error bars sent ± the standard deviation for the determinations. represent ± the standard deviation for the
