TI  - VUV/UV/Chlorine as an Enhanced Advanced Oxidation Process for Organic Pollutant 
      Removal from Water: Assessment with a Novel Mini-Fluidic VUV/UV Photoreaction 
      System (MVPS).

AB  - Vacuum ultraviolet (VUV) and ultraviolet (UV)/chlorine processes are regarded as 
      two of many advanced oxidation processes (AOPs). Because of the similar cost of 
      VUV/UV and UV lamps, a combination of VUV and UV/chlorine (i.e., VUV/UV/chlorine) 
      may enhance the removal of organic pollutants in water but without any additional 
      power input. In this paper, a mini-fluidic VUV/UV photoreaction system (MVPS) was 
      developed for bench-scale experiments, which could emit both VUV (185 nm) and UV 
      (254 nm) or solely UV beams with a nearly identical UV photon fluence. The photon 
      fluence rates of UV and VUV output by the MVPS were determined to be 8.88 x 
      10(-4) and 4.93 x 10(-5) einstein m(-2) s(-1), respectively. The VUV/UV/chlorine 
      process exhibited a strong enhancement concerning the degradation of methylene 
      blue (MB, a model organic pollutant) as compared to the total performance of the 
      VUV/UV and UV/chlorine processes, although the photon fluence of the VUV only 
      accounted for 5.6% of that of the UV. An acidic pH favored MB degradation by the 
      VUV/UV/chlorine process. The synergistic mechanism of the VUV/UV/chlorine process 
      was mainly ascribed to the effective use of (*)OH for pollutant removal through 
      formation of longer-lived secondary radicals (e.g., (*)OCl). This study 
      demonstrates that the new VUV/UV/chlorine process, as an enhanced AOP, can be 
      applied as a highly effective and energy-saving technology for small-scale water 
      and wastewater treatment.
