  • The study simulated a fluidized bed reactor (FBR) for wastewater treatment using the Fenton reaction, an advanced oxidation process.
  • The simulation analyzed the FBR's performance, contaminant concentration profiles, and hydrodynamic properties like Reynolds number and pressure in a 2.8 L volume, achieving a 45% reduction in TOC for phenols at concentrations of 40-90 mg/L within 60 minutes.
  • A scale-up study indicated that the model is applicable up to a 10 L volume, demonstrating the effectiveness of modeling and simulation for designing FBR systems in wastewater treatment.

Article Abstract

Simulation of fluidized bed reactor (FBR) was accomplished for treating wastewater using Fenton reaction, which is an advanced oxidation process (AOP). The simulation was performed to determine characteristics of FBR performance, concentration profile of the contaminants, and various prominent hydrodynamic properties (e.g., Reynolds number, velocity, and pressure) in the reactor. Simulation was implemented for 2.8 L working volume using hydrodynamic correlations, continuous equation, and simplified kinetic information for phenols degradation as a model. The simulation shows that, by using Fe(3+) and Fe(2+) mixtures as catalyst, TOC degradation up to 45% was achieved for contaminant range of 40-90 mg/L within 60 min. The concentration profiles and hydrodynamic characteristics were also generated. A subsequent scale-up study was also conducted using similitude method. The analysis shows that up to 10 L working volume, the models developed are applicable. The study proves that, using appropriate modeling and simulation, data can be predicted for designing and operating FBR for wastewater treatment.

Article Synopsis
  • The study focused on how adding sugar and sugar alcohol binders in the fluidized-bed agglomeration process affects the physical properties of milk protein isolate (MPI) and guar gum (GG) mixtures.
  • The agglomerated mixtures, known as AMGs, were found to have larger, more porous particles that improved solubility and flowability compared to non-agglomerated mixtures (NMG).
  • However, AMGs had lower apparent viscosity and viscoelastic properties than NMG, which decreased further with more binder concentration, indicating a change in interaction between the protein and gum.
