  • Does anaerobic reactor treatment of textile wastewater improve efficiency?
  • The novelty of this hybrid biological study is the treatment of textile wastewater at lower HRT resulting in higher efficiency removal rate (HRT = 54 h combined). Fig. 5. Trends of MLSS concentration and F/M ratio in anaerobic SBR. Fig. 6. Trend of VFA/Alkalinity ratio in anaerobic reactor in treating real textile wastewater.
  • Can anaerobic sludge blanket be used to treat textile wastewater?
  • A hybrid anaerobic–aerobic treatability of real textile wastewater was investigated by using a lab-scale upflow anaerobic sludge blanket (UASB) coupled with a sequencing batch reactor (SBR). The performance of the integrated system was determined under various operational conditions.
  • What is the biological treatment of textile wastewater?
  • The biological treatment of textile wastewaters is based on sequencing anaerobic and aerobic processes providing anaerobic reductive cleavage of the dyes’ azo bond, in which azo dye acts as an electron acceptor; and aerobic breakdown products of azo dyes, aromatic amines.
  • Is aerobic treatment necessary for anaerobically treated effluent reclaim water?
  • Study shows that aerobic treatment is required to increase the treatment level by providing the final polishing to anaerobically treated effluent in order to reclaim water. The optimum HRT for hybrid anaerobic-aerobic system in treating real textile wastewater was found to be 54 h for maximum COD removal.
