Disinfection Of Water Conditioning Systems - Pentair Pro Elite Professional Series Operation Manual

Disinfection of Water Conditioning
Systems
The materials of construction in the modern water
conditioning system 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
These materials are satisfactory for use with polystyrene
resins, synthetic gel zeolite, and bentonites.
5.25% Sodium Hypochlorite
If stronger solutions are used, such as those sold for
commercial laundries, adjust the dosage accordingly.
1. Dosage
• Polystyrene resin; 1.2 fluid ounce (35.5 mL) per
cubic foot.
• Non-resinous exchangers; 0.8 fluid ounce
(23.7 mL) per cubic foot.
2. Regenerant 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.
*The camshaft does not change position between C2 and C3 cycles. C2 is only momentarily displayed.

cubic foot.
2. Regenerant tank conditioners
