Field evaluation of hazardous-waste pretreatment as an air-pollution-control technique. Report for April 1984-May 1985
Three commonly practiced commercial treatment processes were investigated for the removal of volatile organic compounds (VOCs) from hazardous waste: thin-film evaporation, steam stripping, and fractional distillation. The data collected included limitations of the treatment technology, the VOC removal effectiveness, the characteristics of residuals, and cost information. Three thin-film evaporators were evaluated, each treating different types of wastes. There was a large variation in the amount of highly volatile compounds removed by the technique, depending upon the boiling temperature of the waste stream. Four waste streams were treated in a batch-steam stripper. Over 90% VOC removal was obtained in all four cases. Two aqueous/organic waste streams were treated using fractional distillation and over 90% VOC removal was obtained in both cases.
