SYSTEM DISINFECTION

Disinfection Of Water Softeners
The materials of construction of the modern water softener
will not support bacterial growth, nor will these materials
contaminate a water supply . During normal use, a softener
may become fouled with organic matter, or in some cases with
bacteria from the water supply . This may result in an off-taste
or odor in the water .
Some softeners may need to be disinfected after installation
and some softeners will require periodic disinfection during
their normal life .
Depending upon the conditions of use, the style of softener, the
type of ion exchanger, and the disinfectant available, a choice
can be made among the following methods .
Sodium or Calcium Hypochlorite
Application
These materials are satisfactory for use with polystyrene
resins, synthetic gel zeolite, greensand and bentonites .
5.25% Sodium Hypochlorite
These solutions are available under trade names such as
Clorox*. If stronger solutions are used, such as those sold for
commercial laundries, adjust the dosage accordingly .
1 . Dosage
A . Polystyrene resin; 1.2 fluid ounce (35.5 ml) per cubic
foot .
B . Non-resinous exchangers; 0.8 fluid ounce (23.7 ml) per
cubic foot .
2 . Salt tank softeners
A . Backwash the softener and add the required amount of
hypochlorite solution to the well of the salt tank . The salt
tank should have water in it to permit the solution to be
carried into the softener .
