The paper gives results of a bench-scale evaluation to determine the extent to which process wastewaters from the KRW Energy Systems coal gasification process are treatable using commercially proven wastewater treatment technology. (NOTE: The process--formerly called the Westinghouse gasification process--is representative of ash agglomerating fluidized-bed coal gasification technology which has developed to the point where commercial-scale systems are now being planned and which has been the subject of extensive environmental, health, and safety evaluations.) The program was conducted in cooperation with KRW which provided wastewater samples, process information, and technical review. The treatment processes considered in this evaluation were suspended solids removal, steam stripping, cyanide conversion, and biological oxidation. A design basis for each treatment was developed from the bench-scale data and incorporated into a conceptual plant wastewater treatment system design. The treatability data presented show that gasification process wastewaters can be effectively treated using conventional treatment technologies.
