Description:
An all-electrical Shirco carbon regeneration furnace and its air pollution control system have been evaluated for cost and process effectiveness in carbon reactivation at the Pomona Advanced Wastewater Treatment Research Facility. The granular activated carbon used for the Shirco Furnace evaluation study was exhausted in three 1.8 m (6 ft) diameter steel carbon adsorption columns connected in series. The columns treated unchlorinated and unfiltered activated sludge effluent from the 0.44 cu m/sec (10 MGD) Ponoma Water Reclamation Plant. The Shirco carbon regeneration system was found to be as effective as the multiple hearth and rotary kiln furnaces in reactivating the exhausted granular activated carbon. The operation and maintenance cost for the Shirco furnace was, however, found to be higher than those for both the multiple hearth and the rotary kiln furnaces.
