Ion Exchange Systems
Measuring in Cation free and demineralized Water
To produce pure boiler feedwater, alternatively to a reverse osmosis (RO) system, an ion exchange system can be used comprising of cation and anion vessels and a mixed bed for final polishing. Steel pressure vessels filled with ion exchanger resins absorb all salt components (cations and anions) from the feed water. The ion exchanger resins need to be regenerated using strong acidic and caustic solutions.

Sector
2 Applications (1. Conductivity after Cation Exchanger, 2. Conductivity after Anion Exchanger)
Application
Conductivity
Measured Parameter
Key Requirements
- Measuring in low pH and neutral pH water
Application Description
Specific conductivity and cation conductivity needs to be measured after each vessel. To reduce overall cost and downtime for regeneration, these measurements are mandatory to run the system effectively.
Requirements of Application
Amount of chemicals used and production of wastewater can be minimized by optimized control.
