Abstract Both prechlorinated and biological filters achieved more than one-log removal of turbidity. Effluent turbidities for the biological filters normally did not exceed 0.15 ntu and clearly did not exceed the filtered-water turbidity performance requirement of 0.5 ntu. Turbidity measurements did not indicate major performance differences between PC, BWC, and NC filters. Thus, based on turbidity measurements, biological filtration was not considered to degrade filtered-water quality.
