Regardless of which disinfection system is used, the control of bather and other wastes is critical. For example, one active swimmer produces two pints of perpiration per hour in a pool. Perspiration contains a wide range of organic and inorganic contaminants and these will accumulate and combine with chlorine to form the very undesirable combined chlorine form. In bromine systems, although odors and irritation are not a problem with bromamines, the wastes themselves can build up and eventually make water uncomfortable for bathing. The regular removal of these wastes is a must in any system.

The odor that is associated with combined chlorine is often mistakenly referred to as "too much chlorine in the water", but actually indicates that there is too little. The best way to remove these wastes is with regular oxidation. To destroy these wastes, we use either Super Chlorination or Shock Treatment.

We use the phrase "super chlorination" when referring to the use of a sudden large dose of chlorine to destroy wastes. Conversely, the phrase "shock treatment" refers to the use of non-chlorine type shock. In either case, the goal is to destroy and remove bather waste in addition to preventing formation of combined chlorine or accumulation of irritating waste products.
