AB  - The ultraviolet/chlorine (UV/chlorine) water purification process was evaluated 
      for its ability to degrade the residues of pharmaceuticals and personal care 
      products (PPCPs) commonly found in drinking water sources. The disinfection 
      byproducts (DBPs) formed after post-chlorination were documented. The performance 
      of the UV/chlorine process was compared with that of the UV/hydrogen peroxide 
      (UV/H2O2) process in treating three types of sand-filtered natural water. Except 
      caffeine and carbamazepine residues, the UV/chlorine process was found to be 
      59-99% effective for feed water with a high level of dissolved organic carbon and 
      alkalinity, and 27-92% effective for water with a high ammonia content. Both 
      chlorine radicals and hydroxyl radicals were found to contribute to the observed 
      PPCP degradation. The removal efficiencies of chlorine- and UV-resistant PPCPs 
      such as carbamazepine and caffeine were 2-3 times greater than in the UV/H2O2 
      process in waters not enriched with ammonia. UV/chlorine treatment slightly 
      enhanced the formation chloral hydrate (CH), haloketone (HK) and 
      trichloronitromethane (TCNM). It reduced haloacetonitrile (HAN) formation during 
      the post-chlorination in comparison with the UV/H2O2 process. In waters with high 
      concentrations of ammonia, the UV/chlorine process was only 5-7% more effective 
      than the UV/H2O2 process, and it formed slightly more THMs, HKs and TCNM along 
      with reduced formation of CH and HAN. The UV/chlorine process is thus recommended 
      as a good alternative to UV/H2O2 treatment for its superior PPCP removal without 
      significantly enhancing DBP formation.
