  • Page 2: Why Use Sodium Monitoring In Water Treatment Processes

    Our patented calibration solution technique ensures thermal equilibrium. In addition, ABB offer greater security at a lower cost by having: • A worldwide network of companies and agents to ensure backup in most countries.

    Sodium Monitoring in Water Treatment Processes AG/AI-024_4 Installation ABB Sodium monitors are normally located inside the Water Treatment Plant on a rack – preferably in an air-conditioned room. Samples are normally at ambient temperatures so sample cooling should not be necessary (even the polishing plant will be below 55°C).
  • Page 4: Process Description

    Sodium Monitoring in Water Treatment Processes AG/AI-024_4 Process Description Basic Measurement/ Analysis Theory All on-line sodium monitors are based on the use of a sodium ion selective electrode and a reference electrode. The measurement is very similar to that of pH, with the electrode pair also responding to hydrogen ions and changes in sample temperature.
