Clearing The Air

Protecting the health and safety of pool-goers continues to be the number-one concern for aquatic-facility managers and operators.

By June, the season has begun, and the majority of recreation facilities are in full operation. All sanitizing equipment should be operational to meet bather demand.

Chlorine demand will dictate the design of the sanitizing systems for a facility. The demand is based on various parameters:

 

  • Volume (gallons)
  • Average water temperature
  • Presence of cyanuric acid
  • Bather load
  • Direct sunlight/UV exposure
  • Surrounding vegetation and airborne debris
  • Chemical dilution from source water
  • Filter turnover and circulation patterns.

In addition, local and state codes must be reviewed to be sure the systems meet the standards.

Over the past several years, changes by regulators have increased the need for controllers and additional components to ensure bather protection from recreation water illnesses.

New standards also are on the rise for chlorine treatment in response to the science behind disinfectant by-products and their effect on bather health.

Make A Full Equipment Review

Early in the season operators should initiate a thorough review of the existing equipment and recommend any changes or upgrades so the expenditures can be included in budgets.

Maintaining accurate records of chemical purchases, daily chemical additions, and fluctuations in chlorine readings will go a long way in helping to analyze what needs to be improved.

This is also the time to examine existing equipment for age, and to note increased repair activity.

Many facilities are “greening” their pool environments by eliminating toxic chemicals. If the operators are trying to achieve an environmentally friendly facility, a review of the current sanitizers used, as well as chemical storage areas, should be made. Additionally, operators should be confident the sanitizers used are EPA-rated and -approved.

More facilities are adding new bather attractions, such as interactive water features, which require additional chemical demand, so sanitizing equipment should be upgraded to meet regulations.

If the facility is in a renovation stage, look into the new standards imposed by codes to meet higher sanitizer demand.

New sanitizing systems include electrolytic chlorine generation (ECG), Ozone and Ultraviolet (UV) as secondary sanitizers, and controllers that monitor chlorine activity, pH, and Oxidation Reduction Potential (ORP) monitoring. These controllers will interface with the chlorine feeders to achieve the optimal sanitizer levels at all times.
