The primary objective of this research was to determine whether results obtained with laboratory‐scale rapid rate filtration of low turbidity waters could be duplicated during full‐scale operation. With the aid of two field‐scale pilot filters, it was verified that, using proper chemical coagulation, rapid rate filtration can remove high percentages of microscopic particles, including Giardia cysts. Although low temperatures have in the past been thought to hinder the treatment of low turbidity waters, the results of this research suggest that the rapid rate filtration of low turbidity waters can be as efficient at 32°F (0°C) as at higher temperatures.
