Facility Combines Two Technologies, Increases Water Quality

Public Water Supply District #7 in Cass County, Mo., has combined an ultrafiltration membrane system with a ballasted flocculating/clarification system to deliver higher-purity water than ever before. The two treatment systems were designed by Koch Membrane Systems and Kruger of Denmark, respectively.

"Current and upcoming EPA regulations focused us directly towards new treatment techniques," Leonard Whiting, Cass County superintendent, said. "Many plants will not meet the regulations using current treatments.
