Determination of sulphides
With the online analysis system Sulfimax GX online WATER, sulphides or H2S in wastewater can already be determined below the odour threshold. This is achieved by coupling a highly effective gas extraction with a selective detection method.
Applications

  • Online acquisition of the current sulfide concentration
  • Waste water analysis for control systems (pump sump, free level or pressure water pipe)
  • Landfill leachate monitoring
  • Industrial sewage treatment plants
  • Municipal sewage treatment plants
Advantages

  • Automatic sample dosing
  • Hardly any cross-sensitivities due to indirect method
  • Output 4 - 20 mA for integration of the H2S signal into the control system
  • Short measuring intervals allow fast reaction to changes
  • Low maintenance requirements
Features

  • Detection of the true H2S content directly in the liquid phase and thus independent of weather conditions (even in strongly basic samples)
  • Simple calibration
  • Simple, clear software
  • No cross-contamination due to self-cleaning between measurements
  • Long sensor life due to integrated regeneration processes
