PDX ENHANCED DEICER MANAGEMENT SYSTEM

摘要

At the core of the water treatment facility are two anaerobic fluidized bed reactors, designed by Gresham, Smith & Partners. Deicer runoff is passed through a bed of granularactivated carbon, suspending and mixing the media. This allows microorganisms to grow on the entire outer surface of the carbon, which absorb the organic compounds from the deicer fluid and break them down. They convert the effluent to water, carbon dioxide, and methane, which then flow into a separator where gravity forces denser solids to the bottom, and lighter solids and water migrate to the top. The water is clarified and discharged.
