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 commonly known as household bleach.
If stronger solutions are used, such as those sold for
commercial laundries, adjust the dosage accordingly.
1. Dosage
F. Polystyrene resin; 1.2 fluid ounce (35.5 ml) per
cubic foot.
G. 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.
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.
1. Dosage
A. Two grains (approximately 0.1 ounce [3 ml]) per
cubic foot.
2. Regenerant tank conditioners
A. Backwash the conditioner and add the required amount
of hypochlorite to the well of the regenerant tank. The
regenerant tank should have water in it to permit the
chlorine solution to be carried into the conditioner.
B. Proceed with the normal regeneration.
