Commercial pools, hotel pools, health club pools, public pools and school pools can experience the high bather load that makes disinfection a critical public health issue.  In these cases, many pool managers have learned that the traditional chlorine sanitation routine is simply unable to cope with the most dangerous contaminants.  In addition, chlorine interacts with other elements in the water to create unhealthy byproducts like chloramines. Chlorine alone cannot do the job.

In these circumstances, both public health and management prudence indicate operators should choose the safe, effective corona discharge ozone sanitation solution.  DEL’s CD ozone systems can be installed in most pools with a surprisingly small footprint to provide a low-cost sanitation program.

These systems will deliver highly reliable sanitation, killing 99.9% of bacteria and viruses on contact without the noxious byproducts of chlorine.  Operationally, ozone sanitation as a supplementary system permits a reduction of chlorine use both by replacing the chlorine itself and by destroying chloramines that reduce the efficacy of chlorine.  A much smaller residual level of chlorine can be maintained to sanitize the more routine contaminants of the pool.

Public Health Responsibility

Pools that are open to the public in some fashion are susceptible to carrying waterborne diseases and disorders, also known as Recreational Water Illness (RWI).  RWI can include microorganisms like e.coli, giardia, and cryptosporidium, and it also encompasses disorders like swimmer’s asthma which is caused by inhaling chloramines that are a byproduct of chlorine sanitation. 

RWIs pose threats to both the swimmers and to the pool management. The problem is that chlorine sanitation by itself is ineffective against all of these problems.  Luckily ozone sanitation options exist and are recognized as effective and safe.

Public Health Officials Recommend CD Ozone

To address the public health issue, the Centers for Disease Control have sponsored the development of a Model Aquatic Health Code (MAHC) to provide pool managers with guidelines for safe, effective sanitation.  The MAHC requires a “supplemental disinfection system” to be 99.99% effective against contaminants like cryptosporidium.  It has recommended ozone as an effective sanitizer.

CD Ozone vs. UV Ozone

Although UV ozone is recognized by the MAHC, the corona discharge (CD) ozonators by DEL ozone are superior to UV ozone in the ways that count.  CD ozone is more reliable under more conditions (including occluded water) that provide the margin of safety and effectiveness pool operators need.

Food Safety

Product recalls and bad publicity from outbreaks of diseases traceable to a food product are just the tip of the iceberg. The food and beverage industry is actively seeking cost effective ways to ensure food sanitation and ozone applications from DEL are a perfect fit. Ozone clean-in-place and surface disinfection techniques promote food safety at the same time they can reduce energy use, help equipment last longer, save water, and lower or eliminate waste byproducts. In fact, in 2001 the FDA and USDA approved the use of ozone as a non-thermal, antimicrobial direct food additive.  You might be surprised to know how much of your bottled water is sanitized by ozone.

Residential Applications

DEL Ozone technology sanitizes the majority of hot tubs built with ozone over the last 20 years. The corona discharge chip spa ozonator, with its effectiveness and low cost operation, has helped thousands of spa owners enjoy clean, healthy water with less fuss with chemicals.  Visit DEL's spa website to choose your spa ozonator.

Now DEL is bringing ozone sanitation power to residential pools of all kinds, including both above ground pools and inground pools.  Find all the details on pool sanitation at DEL.
