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 brands names of household
bleach. If stronger solutions are used, such as those sold for
commercial laundries, adjust the dosage accordingly.
Dosage
A. Polystyrene resin; 1.2 uid ounce (35.5 ml) per cubic foot.
B. Non-resinous exchangers; 0.8 uid ounce (23.7 ml) per

1. Salt tank softeners
A. Backwash the softener and add the required amount of
hypochlorite solution to the well of the salt tank. The salt

Calcium Hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in
several forms including tablets and granules. These solid
materials may be used directly without dissolving before use.
