This article discusses the Filter Aid Injection Manifold that uses ram water from the house system water supply lines to break the head of the influent water to the filter. Filter aid is fed at low feed rates of about 0.16 mg/L. The ram water and manifold nozzles provide a more uniform and constant dispersion of the chemical, and the higher velocity of the solution creates cleaner feed lines. Results and benefits of using the manifold at the Eugene (Oregon) Water and Electric Board's 72‐mgd conventional surface water treatment plant are discussed.
