Water Treatment Systems: Water Softeners


Description: A class of ion exchange water conditioning equipment which use cation resin to replace positively charged mineral ions with another, more desirable ion (primarily sodium or potassium). Water softeners are primarily used to remove hardness ions calcium and magnesium and low levels of iron. The typical water softener consists of a pressure vessel which holds the cation resin, a control valve with brining system, and a brine tank which holds the salt solution for regeneration.

Pretreatment Requirements: The raw water must be tested before the softener is installed. The minimal testing program should include the following:

1. Sediment: Excessive turbidity caused by sediment in the water can foul a resin bed and reduce its   efficiency. If sediment is present, prefiltration of the water should be considered.

2. Total Hardness: Softeners have limitations on the total hardness levels they can efficiently handle.

3. Iron: A water softener can reduce low levels of ferrous iron in a water supply, usually in the range of 1-5 ppm. A separate iron filter may be needed as well as a softener.

4. Total Dissolved Solids (TDS): Water with high levels of TDS can reduce the efficiency of a water softener by interfering with the exchange sites on the resin beads. High TDS levels may also reduce the capacity of the system.
