The use of activated carbon for removal of phenol from wastewater is a well demonstrated and generally accepted treatment method. The Air Force operates a number of facilities for the depainting of aircraft and related equipment and the wastewater generated sometimes contains high concentrations of phenol. A study was conducted to ascertain both the economical and technical practicality of using a granular carbon system for treating large volumes of this type of phenol bearing wastewater. Basically, this work involved two phases. The initial phase was performed in the laboratory and involved an in-depth characterization of the wastewater and the evaluation of different activated carbons for treating this wastewater. The second phase was performed on-site at Kelly Air Force Base and involved operating a pilot plant for treating phenol wastewater. The carbon was exhausted five times and thermally regenerated four times. The pilot plant was operated intermittently and was on-site for a period of six months. The technical feasibility of using activated carbon on this specific wastewater was demonstrated and the cost of constructing and operating full size plants was determined.
