Commercial Aquatics

Systems for aquatics are certified and 100% MAHC-compliant.

Water sanitizer systems provide clean and clear water for aquatic facilities where clean is critical.

Our units meet or exceed the standards of safety and efficacy for secondary sanitization systems set forth by the CDC sponsored Model Aquatic Health Code (MAHC). MAHC was created by the U.S. Centers for Disease Control (CDC).

DEL units will destroy 99.9% of organic contaminants such as bacteria, viruses, and pathogens – including Cryptosporidium – as well as multiple inorganic contaminants such as lotions and perfumes. Our systems are also energy efficient and reduce chemical usage by 60-90% depending on the specific application.


MAHC language specifically states, “Due to the risk of outbreaks of Recreational Water Illnesses (RWI’s) associated with sanitizer-resistant pathogens such as Cryptosporidium and Giardia, it is strongly recommended that all aquatic facilities include Secondary Disinfection Systems (SDSs) to minimize the risk to the public associated with these outbreaks.”

The MAHC continues, “. . . .Secondary Disinfection Systems are required for: therapy pools, wading pools, swim school pools, and aquatic play facilities/features.”

All ozone systems must be sized in accordance with the MAHC. We ensure all sanitizer systems for aquatics are 100% MAHC-compliant.

Only ozone systems that are certified by an American National Standards Institute (ANSI)-Accredited third-party testing and certification organization to verify that they provide a 3 log (99.9%) inactivation of Cryptosporidium parvum in the side-stream applied full flow are qualified to be an SDS. This standard is in addition to the current ANSI/NSF Standard 50.
