Microbiological and Performance Evaluation of Sequencing Batch Reactor for Textile Wastewater Treatment
This study focused on laboratory‐scaled and real‐scaled treatment plant performances and microbiological investigations for the optimum treatment of textile industry wastewater performed with sequencing batch reactor (SBR). As a result of experimental studies of laboratory‐scaled SBR treatment unit, optimum treatment efficiency was taken from 0.5 h filling to 1.5 h. reaction to 1.5 h. settlement to 0.5 h. discharge‐idle periods. Average chemical oxygen demand (COD) removal efficiency of SBR of laboratory‐scaled textile industry was 75%, whereas average turbidity and color removal (coloration number [RES, m−1] 586 nm) efficiencies were 90% and 75%, respectively. Optimum reaction and settlement periods were used in a real‐scaled plant, and plant efficiency was examined for parameters such as COD, phenol, pH, mixed liquor suspended solids (MLSS) and sludge volume index (SVI). In this study, optimum reaction and settlement periods for treatment of textile industry wastewater were determined within a SBR in a laboratory‐scaled plant. These reaction and settlement periods were verified with the measurement of COD, color, and turbidity parameters. Floc structure and protozoa‐metazoa species of activated sludge in a SBR were also determined. Optimum reaction and settlement times were used in a real‐scaled plant, and plant efficiency was examined for COD, Phenol, pH, MLSS, and SVI parameters. The corresponding values were found as appropriate, acceptable, and meaningful because of variance value of statistical analysis. Protozoa and metazoan in the activated sludge in the laboratory‐scaled plant were investigated. Peranema sp., Epistylis sp., Didinium sp., Chilodonella sp., Opercularia sp., Vorticella sp. as protozoa species and Habrotrocha sp., Philodina sp. as metazoa species were determined.
