SYSTEM DISINFECTION
Disinfection Of Water Conditioners
The materials of construction of the modern water conditioner will not
support bacterial growth, nor will these materials contaminate a water
supply. During normal use, a conditioner 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 conditioners may need to be disinfected after installation and some
conditioners will require periodic disinfection during their normal life.
Depending upon the conditions of use, the style of conditioner, 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. Brine tank conditioners
A. Backwash the conditioner and add the required amount of
hypochlorite solution to the well of the regenerant tank. The
regenerant tank should have water in it to permit the solution to be
carried into the conditioner.
B. Proceed with the normal regeneration.
