(by the use of ion exchange resins) to produce pure, plant where anions are exchanged with hydroxyl ions mineral-free water. ABB sodium monitors are used and cations are exchanged with hydrogen ions for continuous monitoring of sodium in the process...
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).
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.
