Systèmes d’échange d’ions

Ion Exchange Systems

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

Production of pure boiler feedwater

Application

2 Applications (1. Conductivity after Cation Exchanger, 2. Conductivity after Anion Exchanger)

Measured Parameter

Conductivity

Key Requirements

Measuring in low pH and neutral pH water

Measuring in Cation free and demineralized 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.

Why Knick?
Knick’s conductivity sensor SE604, recommended for this application, is the only sensor with removable outer electrodes for easy cleaning and handling. SI/SF (System Integrators/System Fabricators) and plant manufacturers appreciate our reliable, sophisticated and accurate solutions.
