Abstract
This study investigated several methods currently available to reduce the level of pollutants in an industrial plant wastewater stream. Its purpose was to screen these treatment processes. As a result of this screening, further in-depth evaluations should be considered. The study was limited to a detailed evaluation of only five priority pollutants in order to minimize the analytical workload on the project. The five selected for testing the effectiveness of carbon adsorption, resin adsorption, and steam stripping represented compounds occurring at significant levels in the sample. The results of the study indicated high removal efficiency for these five priority pollutants by carbon adsorption and resin adsorption. Although steam stripping reduced chlorobenzene, p-dichlorobenzene and nitrobenzene concentrations by at least fifty percent, it is not effective, under the test conditions, for the priority pollutants phenol or dinitrotoluene. Costs for treatment of streams similar to the stream tested are expected to be high, in the order of $2 to $3 per 1000 liters (265 gallons) for flows of about 1130 liters per minute (300 gallons per minute). Cost effectiveness may favor use of carbon adsorption over resin adsorption. Combination systems are of doubtful value based on the pollutant levels present in the sample stream since they offered no economic advantage over single process operations.
