  7. Abstract:
  8. Population growth and community development has a large role in the demand for fresh water for a variety of uses. In recent decades, over-harvesting and abusing of water resources has led to water crisis. On the other hand, the increase in various pollutants, in addition to environmental hazards, is a threat to groundwater pollution and the existence of valuable fresh water. Due to the potential hazards of emerging pollutants, new treatment technologies such as advanced oxidation and photocatalytic methods are being developed. One of the contaminants resistant to traditional treatment methods is textile contaminants. In this research, by designing and constructing a photocatalytic reactor, the efficiency of this method on the removal of Basic Red 46 dye in a continuous system has been studied by advanced oxidation method. The FeVO4 nanoparticles, which are modified using the MIL-100 (Fe) metal-organic framework nanostructure, were exposed to the contaminant solution and visible light by immobilizing on the glass surface and flowing the liquid in a film reactor. Structural properties of nanoparticles were fully characterized using FESEM, DRS, XRD and FT-IR analyzes. After immobilizing the
    nanoparticles in a falling film photoreactor, the influences of process parameters such as
    liquid film thickness and flow rate on the removal efficiency of the contaminant have
    been investigated. The results showed a high photocatalytic activity in visible light and
    degradation of Basic Red 46 dye up to 81% in 140 minutes. Also, the optimal pH of 3 and
    the film thickness and flow rate were determined to be 1 mm and 0.5 liters per minute,
    respectively.During the process, temperature controlled by circulating water. This method
    has a good potential in removing textile pollutants by using a continuous photoreactor
