Polishing of pretreated dye wastewater using novel sequencing batch reactors.
Novel, aerobic sequencing batch reactor technology was tested as a polishing step for anaerobically treated textile wastewater containing dye. Operation cycle times of 6, 8 and 12 hours were studied using discrete phase periods. The SBRs were able to further remove influent dye concentration of as little as 5 mg/L, and remove highly variable loadings of COD and SS to effluent levels of 100 and 20 mg/L respectively.
