Abstract |
The report gives results of a study concerned with BATEA for the textile manufacturing industry. The level of removal of specific toxic pollutants and toxicity (measured by results of bioassays) attained by selected tertiary systems treating secondary effluents from textile plants was examined. Tertiary treatment systems (unit processes arranged in various ways) were ranked according to their apparent capabilities for removing specific toxic pollutants and toxicity. Unit processes used included flocculation/sedimentation, multimedia filtration with and without precoagulation, granular activated carbon adsorption, and ozonation. |

The report gives results of a study concerned with BATEA for the textile manufacturing industry. The level of removal of specific toxic pollutants and toxicity (measured by results of bioassays) attained by selected tertiary systems treating secondary effluents from textile plants was examined. Tertiary treatment systems (unit processes arranged in various ways) were ranked according to their apparent capabilities for removing specific toxic pollutants and toxicity. Unit processes used included flocculation/sedimentation, multimedia filtration with and without precoagulation, granular activated carbon adsorption, and ozonation. The assessment of the treatment systems was based on specific toxic pollutant analysis data and on bioassay data gathered at eight textile plant locations where the treatment systems were tested. Samples from secondary and tertiary effluent streams were analyzed for specific toxic pollutants. Based on apparent specific toxic pollutant removal and toxicity removal, multimedia filtration-activated carbon was the best system. Tertiary treatment systems whose effluents contained a high level of residual coagulant appeared to be more detrimental to water quality, based on bioassays, than systems not using coagulants. |
