Bench-scale studies were used to investigate the effectiveness of dissolved-air flotation (DAF) for the removal of Cryptosporidium parvum oocysts from a drinking water supply. Oocysts were spiked into a natural water at a concentration of 3-4 x 10(5) oocysts/L. Results indicate that DAF achieved a >2-log removal of oocysts under a variety of conditions. In addition, flotation was a superior clarification process to sedimentation for the conditions tested. Coagulation and DAF conditions that minimize residual turbidity and maximize the removals of organic matter are conditions that produce high log removals of Cryptosporidium.
