AB  - In this study, a horizontally rotating disc recirculated (HRDR) photoreactor 
      equipped with two UV lamps (6 W) was designed and fabricated for photocatalytic 
      removal of p-nitrophenol (PNP). Photocatalyst (TiO(2)) nanoparticles were 
      immobilized onto a high-density polyethylene (HDPE) disc, and PNP containing 
      solution was allowed to flow (flow rate of 310 mL min(-1)) in radial direction 
      along the surface of the rotating disc illuminated with UV light. The efficiency 
      of direct photolysis and photocatalysis and the effect of rotating speed on the 
      removal of PNP were studied in the HRDR photoreactor. It was found that 
      TiO(2)-P25 nanoparticles are needed for the effective removal of PNP and there 
      was an optimum rotating speed (450 rpm) for the efficient performance of the HRDR 
      photoreactor. Then effects of operational variables on the removal efficiency 
      were optimized using response surface methodology. The results showed that the 
      predicted values of removal efficiency are consistent with experimental results 
      with an R(2) of 0.9656. Optimization results showed that maximum removal percent 
      (82.6%) was achieved in the HRDR photoreactor at the optimum operational 
      conditions. Finally, the reusability of the HRDR photoreactor was evaluated and 
      the results showed high reusability and stability without any significant 
      decrease in the photocatalytic removal efficiency.
