CDC logoNOTICE: Secondary Disinfection (Ozone/UV) is now Mandatory on all Increased Risk Aquatic Venues as states in the Model Aquatic Health Code from the CDC

Turn-Key Solution to MAHC Secondary Disinfection Requirement

Prozone Hybrid Ozone/UV/AOP systems are the solution for Secondary Disinfection. In addition to meeting all the MAHC requirements, Prozone’s patented AOP Hybrid 20,000 arc tube produces high concentration levels of Ozone and Hydroxyls through Advanced Oxidation Processing (AOP) while also producing Germicidal UV-C. The Hybrid produces the most powerful oxidizers, Ozone and Hydroxyls, to destroy crypto, other microorganisms, bacteria, viruses and algae on contact – with no harmful by-products. The Ozone and AOP produced by the systems also breaks down harmful chemicals and acts as a flocculent, causing total dissolved solids to be suspended and easily removed by the water filtration process.

Prozone has 40 years experience in the execution of ozone projects commercially and in the pool and spa industry. Most systems are designed as integrated water treatment packages which only require the end-user to connect power, water in/out, and off-gas venting: true turn-key solutions.

Keeping Spray Pads and Other Water Features Clean and Healthy is Now Mandatory

Prozone Hybrid Ozone/UV/AOP Systems Make it Simple

Spray pads, splash pads, wet decks, spray parks and other water features are becoming more and more popular and common. These interactive water play areas appeal to all ages but especially to young children. Often the children are under five years old and not yet potty trained. Although these venues may not have any standing water, the spray water will rinse any contaminants that might be on the bathers into the drain water which is re-circulated. These contaminants include viruses, bacteria, and other microorganisms including cryptosporidium which is the number one cause of Recreational Water Illnesses (RWI). This is the main reason they are considered Increased Risk Aquatic Venues.

Chlorine is not enough to keep a pool clean and safe
Prozone kills cryptosporidium

RWI are caused by microorganisms in and around the water. Some of the microorganisms are very tolerant to chlorine. In particular, cryptosporidium (crypto for short) has become the leading cause of swimming pool-related outbreaks of diarrhea involved illness. Chlorine alone cannot clean a pool infected with crypto.  A single outbreak can sicken thousands and can lead to immediate shut-down of the infected facility resulting in sometimes devastating financial loss.

RWI Outbreaks Are Increasing

RWI (Recreational Water Illness) outbreaks are increasing; up from 15 outbreaks a year (1993–2002) to 34 outbreaks a year (2003–2012). This is one of the reasons the CDC (Center for Disease Control and Prevention) has developed the Model Aquatic Health Code (MAHC). Federal, state, and local public health officials and the aquatics sector formed an unprecedented collaboration to create the MAHC.

The MAHC is a guidance document based on scientific research and best practices designed to help local and state authorities make swimming and other water-related activities safer and healthier. Although the MAHC is not Federal Law, more and more local and state governing authorities are adopting the code. In the MAHC, it is recommended that public pools use Secondary Disinfection – specifically either ozone or UV systems. And it is required for Increased Risk Aquatic Venues: wading pools, therapy pools, swim school pools, spray pads and other interactive water play venues.

Advantages of Ozone & Hydroxyls

  • Achieves sanitation by the inactivation of cysts, viruses, and bacteria while controlling biofouling
  • Enhances the effectiveness of chlorine by recycling the combined chlorines back to their free chlorine state reducing chemical costs by 60-80%
  • Reduces the amount of shocking required to maintain the water
  • Eliminates odors and eye irritation
  • Enhances filtration by oxidizing contaminants and forming precipitants
  • Reduces corrosion of structures and equipment through chloramines reduction
  • Readily oxidizes organic compounds

- Prozone ozone generators destroy cryptosporidium (crypto), other microorganisms, bacteria, viruses and algae on contact, with no harmful by-products.

UV alove is not enough to kill crypto

Advantages of Prozone Ozone over UV Sterilizer Alone

Prozone OZONEUV Sterilizer
+ Ozone kills cryptosporidium parvum+ UV inactivates cryptosporidium parvum only if intensity is high
+ Ozone kills microorganisms+ UV inactivates most singular microorganisms
+ Ozone is a powerful oxidizer- UV is not an oxidizer
+ Ozone by products pass into the pool at low levels to provide additional oxidation- UV affects the water only as is passes closely through the UV chamber
+ Ozone precipitates cloudy water, and is a micro-flocculent, which clears water- Only clear water can be effectively dosed with UV; cloudiness and shielding particles in the water can absorb the UV light
+ Ozone oxidizes the organics and inorganics that create chloramines, returning them to free chlorine- Only medium pressure UV breaks down chloramines that have been previously created
+ Ozone utilizes ORP (REDOX) to measure the cleanliness of the water- Most UV systems utilize a UV intensity meter which measures the UV dose regardless of water quality; UV has no effect on ORP
+ Ozone's reaction in conjunction with free available chlorine and in a pool will not affect the FAC levels; except by chloramine destruction- UV can break down free available chlorine in the water while it breaks down chloramines
+ Ozone cells require periodic replacement; no hazardous components- Mercury vapor lamps are replaced at 3-12 mos. and cleaned monthly; disposal procedures must be considered as hazardous waste
+ Ozone destroys biofilm; keeps lines clean- UV does not prevent biofilm
+ Ozone destroys Humic and Fulvic Acid- UV does not affect Humic and Fulvic Acid
Oxidation leads to Precipitation which leads to Filtration Heading

1 – Oxidation

Ozone destroys algae, viruses, and bacteria on contact with no harmful by-products. Ozone oxidizes combined chlorine and bromine, freeing them to be continuously reused. Therefore the use and cost of chemicals is reduced.

  • Ozone reacts with bather loading and combined halogens
  • Reduces contaminants to inert compounds or carbon dioxide and water
  • Oxidizes combined halogens
2 – Precipitation

It breaks down harmful chemicals and acts as a flocculent, causing total dissolved solids to be precipitated and easily removed by the water filtration process.

  • Ozone removes metals (iron, manganese, zinc, copper, etc.)
  • Oxidized organics also precipitate
  • Filtration and clarification are enhanced by precipitation
3 – Filtration / Sanitation / Disinfection

Ozone is the most powerful sanitizer, non-selectively killing all microorganisms while producing no harmful byproducts.

  • Ozone is the most powerful disinfectant available
  • Rapidly kills bacteria and viruses

Prozone Reduces Biofilms – Safely, Effectively

All water contains naturally occurring forms of bacteria and contaminants. Add human bodies to the mix and the load goes up with each swimmer shedding billions of bacteria and contaminants. Chlorine cannot be relied on alone to remove or neutralize the bacteria and bather load because bacteria builds colonies called biofilms. These biofilms are very sticky and adhere not only to each other but to most surfaces. Biofilms permeate pipe lines, filters, pool fittings, jets and spray heads harboring Legionella, Cryptosporidium, Staphylococcus, and other kinds of harmful microorganisms. Combining Ozone and UV Germicidal creates Advanced Oxidation Processing – an unbeatable combination. The pure ozone produced by Prozone ozonators rips through biofilms and then oxidizes (decomposes) the resulting free matter into flocculants that are easily removed by filtration. The water purification and filtration cycle is more efficient and the chemical usage is reduced 60-80%.
