AB  - Synthetic wastewater containing different concentrations of 2,4,6-trichlorophenol 
      (TCP) was biologically treated using a novel rotating perforated-tubes biofilm 
      reactor (RTBR) for chemical oxygen demand (COD), TCP and toxicity removal. 
      Performance of the reactor was investigated as function of major operating 
      variables such as the feed TCP and COD concentrations and A/Q (biofilm surface 
      area/feed flow rate) ratio. A Box-Behnken statistical experiment design method 
      was used by considering the feed TCP (0-400 mg L(-1)), COD (1,000-4,000 mg L(-1)) 
      and A/Q ratio (23-163 m(2)dm(-3)) as the independent variables while percent TCP, 
      COD, and toxicity removals were the objective functions. The results were 
      correlated with the quadratic model since this was found to be the most suitable 
      one. Response function coefficients were determined by correlating the 
      experimental data with the response function. Percent TCP, COD and toxicity 
      removals estimated from the response functions were in good agreement with the 
      experimental results. TCP, COD and toxicity removals increased with increasing 
      A/Q ratio and decreasing feed TCP concentrations. Percent toxicity removals were 
      always lower than TCP removals indicating presence or formation of some toxic by 
      products from TCP biodegradation. For the feed TCP of 400 mg L(-1), the optimum 
      conditions resulting in maximum COD (99%), TCP (100%) and toxicity (93%) removals 
      were A/Q ratio of nearly 165 m(2)dm(-3) and feed COD of 2,985 mg L(-1).
