TI  - Treatability study of 3,3',4',5-tetrachlorosalicylanilide (TCS) combined with 
      2,4,6-trichlorophenol (TCP) to reduce excess sludge production in a sequence 
      batch reactor.

AB  - The present study investigated the synergistic effects of a novel combined 
      uncoupler of TCS and TCP on excess activated sludge reduction during a 60-day 
      operation using a sequence batch reactor (SBR). Response surface methodology 
      (RSM) was employed to obtain the optimal dosage of the combined uncoupler. The 
      results of 60-day operation demonstrated the combined uncoupler had effectively 
      reduced the sludge yield by approximately 52%, without serious affecting the 
      substrate removal efficiency. The high sludge reduction rate revealed that it was 
      feasible and effective to utilize a combined uncoupler to limit excess activated 
      sludge. The three-dimensional excitation-emission matrix (EEM) fluorescence 
      spectroscopy analysis of activated sludge with different metabolic uncouplers 
      indicated that tryptophan, tyrosine protein-like substances and tryptophan, 
      tyrosine amino-like substances were reduced by adding a combined uncoupler. 
      Moreover, the variation of sludge components provided a better understanding of 
      the effects of uncouplers on activated sludge reduction.
