In a direct filtration plant, filter operation and maintenance are critical to ensuring safe, potable water for consumers. Filters that do not operate to their full potential compromise the productivity and quality of filter effluent, increasing the likelihood of particles and pathogenic microorganisms (e.g., Giardia, Cryptosporidium) passing into the filtrate. This article describes how the Lake Gaillard Water Treatment Plant in Branford, Connecticut, used a surveillance program and turbidity and particle counting measurements to monitor filter performance that enabled water treatment plant operators to pinpoint potential problems and develop programs to optimize performance.
