| Abstract |
A 2-year study was conducted of various simple water filtration systems potentially appropriate for high-quality surface waters serving small systems. A slow sand filter without coagulant and a direct, rapid filter with coagulant were operated in parallel. Direct filtration with and without flocculation were compared in parallel in one phase of the study; declining- and constant-rate filtration were compared in parallel in another phase. The study was designed to emphasize simple treatment systems for small supplies where operational skill and attention may be lacking. The systems were compared while monitoring turbidity, particle count, and coliform bacteria in the influent and filtered water. |
