Under the Surface Water Treatment Rule, many previously unfiltered supplies of high quality may be treated by direct (coagulation, flocculation, filtration) or contact (coagulation, filtration) filtration; we need an improved understanding of the role of suspended particle size and flocculation in filtration performance. For example, in previous laboratory and field studies, providing flocculation has caused either an increase, decrease, or no change in head loss development as compared to contact filtration. The objective of this study was to investigate the effects of chemical addition and flocculation duration on filtration performance as measured by particle removal and head loss development.
