Pool-Water Sanitation

Pool-water sanitation is complex, with several variables to manage to ensure the water is healthy for contact (and unplanned consumption), clear enough to monitor bathers safely, and visually appealing. In its simplest definition, sanitation is typically a chemical that kills germs. In order of importance, a pool-sanitation system includes:

  • Disinfection
  • Circulation
  • Filtration
  • Evacuation.

Almost every pool is initially filled with clean drinking water, whose supply system and quality meet the minimum standards of the

Environmental Protection Agency and the local health department. The water is initially disinfected to a high standard, but the disinfectant capacity of this water must be increased in order to process the billions of additional viruses, bacteria, parasites, pathogenic amoebae, fungi, and algae fungi that will eventually enter the water from the air, insects, pests, and people.

Disinfection

Great pool water begins with disinfection. Clean, potable water is enhanced to prevent recreation water-illnesses without exceeding the chemical tolerance of bathers. Stabilizers, acids, and other chemicals all play a role in balancing the disinfection capacity to reduce corrosion of the circulation system. A UV system functions as a second disinfection strategy as it kills many bacteria through intense light exposure. The UV system requires a circulation component to pull and push the water into and through the light chamber; its overall effectiveness is so high that it helps reduce the need of chemical disinfectants.

Circulation

Filtration safely collects and contains unwanted debris and trash that enter the pool so they are no longer able to make contact with bathers.  Photo Courtesy Of Melissa Lockwood, Assistant Manager, YAS Waterworld Abu Dhabi

into the pool. The circulation loop makes a UV system function. Circulation with a chemical feeder system (currently required by nearly all health departments) allows the operator to continually replace the chemicals being depleted by the environment (sunlight), and through oxidation, which kills microscopic organics.
