4.2 Sizing a softener (single unit)
4.2.1 Parameters to be considered
Whenever installing a softener, it is preferable to have full water analysis to ensure the inlet water
content will not affect the resin bed.
Tip
Please consult your resin manufacturer specification!
To ensure that no additional pretreatment prior to softening is required.
The below sizing method can be applied for both residential and industrial softeners.
The sizing of a softener must be based upon certain parameters:
• inlet water hardness;
• peak flow rate and nominal flow rate;
• service velocity;
• salt dosage.
