  • What is fluorescent tracing in cooling water systems?
  • Fluorescent Tracing in Cooling Water Systems. To accurately measure the concentration of a treatment chemical in cooling tower water has been a challenge. Many reasons account for this challenge. Some are technical and some economical.
  • What is Nalco PTSA tracing?
  • Nalco pioneered the fluorescence tracing technology in the monitoring and control of cooling systems.1,2 After many year research, Nalco discovered a fluorescent chemical PTSA (1,3,6,8-Pyrenetetrasulfonic acid, tetrasodium salt) that can meet stringent requirements as cooling water tracer.
  • What is Nalco TRASAR® technology?
  • The major industrial applications refer to NALCO TRASAR® technology used for automated feed control cooling systems and reverse osmosis systems [89, 90]. Till now Nalco has been using Trasar® technology for approximately 30 years. Trasar® operates a chemically “inert” molecule that is highly fluorescent.
  • Is Nalco a tagged polymer?
  • This can be a labor- intensive production process. In order to overcome the limitations mentioned above Nalco introduced a dispersant polymer that contains a fluorescent “tag”. The tagged polymer is claimed to have equal effectiveness as a dispersant compared to the standard, untagged polymer.
