Because the conventional jar test is ineffective for determining optimal coagulant dosages for low turbidity waters, utilities employing rapid-rate filtration of such waters may fail to maximize treatment efficiency for lack of a simple bench-scale test for determining coagulant dosage. Using terms useful to water treatment plant operators, this article describes a simple bench-scale procedure for determining coagulant dosages for raw water supplies with turbidity levels of 1 ntu or less. The authors explain the protocol for their jarfiltration test and present documentation on test validity. Includes 15 references, table, figures.
