The C3500 D (photo) utilizes 500-W ultraviolet (UV) lamps in a small footprint to provide overall efficiency and economic savings compared to other low-pressure, high-output (LPHO) systems, says the manufacturer. The high-wattage system relies on a patent-pending design, which hydraulically “mixes” water across three sets of delta-shaped (D) wings while minimizing the head loss and exposing the water to a high light dose to efficiently treat the water. The C3500 D utilizes calibrated UV sensors and flowrate to control the dose, helping to minimize operating costs and provide longer lamp life. — Calgon Carbon Corp., Pittsburgh, Pa.
