Technical and Economic Evaluation of BATEA Textile Guidelines

摘要

The report gives results of a project to determine if the Best Available Technology Economically Achievable (BATEA) effluent guidelines promulgated by EPA in 1974 for the textile industry can be achieved by recommended advanced wastewater tertiary treatment technologies. Pilot scale treatment units in two identical trailers were used at 19 textile plants participating in the field evaluation phase of the project. The unit operations were tested on biologically treated effluent from existing facilities at each plant. The most effective treatment was identified for each plant and operated continuously long enough to statistically determine the quality of the treated effluent. In all cases results were compared to BATEA values calculated from the promulgated guidelines and actual production information from the plants during the trailer visits. The comparisons indicated that technical achievement of the BATEA guideline limits for the various criteria pollutants was not consistent in all categories. The cost of installing and operating the selected BATEA tertiary operations in commercial textile plants was determined and guidelines for estimating these costs were established.
