TI  - Reducing effect of aerobic selector on the toxicity of synthetic organic 
      compounds in activated sludge process.

AB  - The effects of phenol, 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP) and 
      1,2,4-trichlorobenzene (1,2,4-TCB) on the biodegradation kinetics of the 
      conventional activated sludge system (CASS) and the selector activated sludge 
      system (SASS) were investigated. Experiments were carried out using a 
      respirometric method on unacclimated biomass from two lab-scale systems that were 
      operated with the sludge age of 8 days. Toxicity of the test compounds for both 
      reactors were arranged according to EC(50) (effective concentration) values in 
      order as: 1,2,4-TCB>2,4-DCP>2-CP>phenol. All selected test compounds induced 
      higher inhibition effect in the CASS. The SASS appeared to reduce inhibition 
      effect in comparison to the CASS, by 21.36%, 66.95%, 64.37% and 33.33% for 
      phenol, 2-CP, 2,4-DCP and 1,2,4-TCB, respectively. Consequently, the SASS may be 
      recommended as a promising configuration alternative for the waste streams 
      containing toxic compounds.
