TI  - A new mathematical model to evaluate simazine removal in three different 
      immobilized-biomass reactors.
PG  - 1035-42
AB  - A new mathematical model based on the cinetical Langmuir equation is developed to 
      interpret and predict the effectiveness of simazine (SZ) removal in 
      immobilized-biomass reactor (IBR), to consider herbicide-support affinity (Cx), 
      and herbicide-cell affinity (Cy). Three solid supports: sepiolite monolith, 
      granular sepiolite, and alginate were used in pilot-scale reactors that were 
      inoculated with Klebsiella planticola DSZ. The abiotic process was analysed by 
      measuring the SZ sorption capacity of the reactor supports. Sepiolite monolith 
      showed the maximum value for herbicide-support affinity (28.02+/-0.9%). The 
      effectiveness of the biotic process was estimated considering the formation of 
      biomass and SZ biodegradation. Granular sepiolite showed either higher affinity 
      with SZ and viability rate (0.90) throughout the process, and SZ removal rate was 
      3.39+/-0.06 mg/h. The mathematical model presented in this paper provides useful 
      insights into the interpretation of experimental data as well as prediction for 
      the implementation of biological reactors.
