WaterSolutions Steps to Design an Ion Exchange Resin System

Accurate system design is critical to getting the most from a water treatment system. Since dozens of factors can impact the productivity of the system, the CADIX system design software program from Dow offers precise design recommendations to optimize system performance.

The goal of the designer of an ion exchange system is to ensure that the correct water quality and quantity is delivered with optimized regenerant consumption and capital cost. The optimum design depends on the relative importance of these parameters. Each are described in the following sections.

How to Design an Ion Exchange Resin System:

Step 1: Regeneration System Selection
Step 2: Selection of Layout and Resin Types (Configuration)
Step 3: Chemical Efficiencies for Different Resin Configurations
Step 4: Atmospheric Degassifier
Step 5: Resin Operating Capacities and Regenerant Levels
Step 6: Vessel Sizing
Step 7: Number of Lines
Step 8: Mixed Bed Design Considerations
