The technical and economic feasibility of treating a combined stream of coke plant waste water and blast furnace blowdown water in a coupled fluidised bed process, operated in the denitrification-denitrification flow mode, was evaluated. More than 90% removal of total nitrogen was achieved at a total system hydraulic retention time of 4.5 h. Removal of other conventional contaminants, including filtered organic carbon, phenolic compounds, thiocyanate, and cyanide consistently approached or exceeded 90%. Capital costs associated with treatment of 4950 m/SUP/3/d of combined waste water were estimated to be 2.3 million Canadian dollars. Direct operating costs were calculated to be 0.14 Canadian dollars m/SUP/3 treated effluent.
