A pilot-plant-sized limestone contactor was constructed at Port Simpson, B.C., and was evaluated for its ability to treat the water supply (low-pH, low-alkalinity water from a creek source) for corrosion control and to condition it for flocculation. Conducted over two months, detailed testing of the limestone contactor involved evaluating performance when it was open and when it was closed to the atmosphere, at various contact times, and at a wide range of flows. Results show that a limestone contactor is effective in treating Port Simpson water for corrosion control and that performance did not deteriorate during continuous operation for 20 months. Although the raw water samples tested had a limited range of color, results showed that the contactor is effective for conditioning water for flocculation to remove color. Includes 27 references, tables, figures.
