Can softened water be used directly as purified water? It depends on downstream requirements.
Conventional softening mainly addresses hardness-related issues and cannot be equated with removing all dissolved salts. Whether additional treatment is needed depends on the water application.
Before purchasing, provide technical staff with downstream equipment instructions, feedwater information and the parameters that need to be controlled. Do not determine the equipment configuration from a name alone.
Information that can be recorded for this inquiry
| Item to check | Information or records | Confirm the application |
|---|---|---|
| Softening objective | Hardness requirements and units | Define the treatment task for calcium and magnesium ions |
| Feedwater conditions | Hardness testing and water consumption | Check the resin and regeneration arrangements |
| Equipment using the water | Make-up water requirements and operating records | Confirm whether other processes are also needed |
Why should other parameters also be checked for softened water?
Softening primarily targets hardness; it is not the same as salt removal or disinfection. Requirements for other downstream water quality parameters should be based on equipment instructions and applicable requirements.
