Types of surveillance systems

  • With chemicals at line or off line
    • Automated lab analysis (Flow Injection Analysis (FIA) & Sequential Flow Injection (SIA))
  • Sensors “without” chemicals online or inline
    • Ion selective electrodes
    • Photometric
      • Calorimetric
      • UV absorption (colour, DO)
      • UV-Vis absorption (COD, TOC, BOD)
  • Virtual sensors (soft sensors) online
