Specifying details for the Titanium AOP

  • The water purification and disinfection unit shall break down and destroy all waterborne organism, to include fungi, yeast, amoebae and viruses by the use of Hydroxyl Radicals.
  • The purification and disinfection process will take place by means of an Advanced Oxidation Process.
  • Photo-Catalytic Oxidation will be created by photonic energy at wavelength 254nm and Titanium Dioxide that will generate Hydroxyl Radicals.
  • The body of the unit shall be of Titanium construction with a Titanium Dioxide Crystal coating applied to the internal surfaces of the reactor body to maximize the Photo-Catalytic reaction creating Hydroxyl Radicals.
  • The Photo-Catalytic Oxidation shall have a Redox Potential of 3.21 and the Hydroxyl Radicals a Redox Potential of 2.8 to ensure complete oxidation of all waterborne organisms and organic matter.
  • No additives shall be used in the process and no harmful residuals shall be formed.
  • The unit shall include a full controls system that runs from a 230V 50Hz fused spur supply. The controls should include facilities for a remote control system, failure indications, UV intensity monitor, water temperature measurement, mild start function and soft heating function.
  • Water purification and disinfection units shall be Titanium AOP from BrightWater Environmental Ltd or equal and approved subject to a technical submittal demonstrating compliance with the above criteria.
