Ozone Generation and Management Systems

An ozone system consists of two basic components that ensure optimum performance at the lowest operating cost:

1. The ozone generation system
2. The ozone management system

The ozone generation system creates ozone from on-board oxygen concentrators. The ozone management system efficiently dissolves the ozone into the water while ensuring that no undissolved ozone is available to off-gas in the pool equipment room or at the pool water surface. Ozone dose is automatically controlled with an oxidation reduction potential (ORP) controller/monitor maintaining proper ozone levels in the water.

Together, the ozone generator and ozone management system operate in unison and are easily installed. The ozone is introduced after the filtration (and heater), and before any chlorine feeders. The side-stream flow is normally 15 to 25 percent of the main flow, depending on the size and type of application. The output of ozone is increased as the water quantity, water temperature or organic loading increases.

Pool Water Quality from DEL Technology

In public recreational water, ozone is used in conjunction with chlorine to enhance pool water clarity and quality and swimmer protection with ozone’s potent and rapid oxidation of organic and inorganic compounds. Ozone is also cost-effective, uses little energy, is safe for pool patrons, and helps to protect the HVAC system from structural degradation. 

Swimming pool water quality is simply maintained by the installation of a DEL ozone generator, also known as an ozonator, to inject ozone into the flow of water through the pool’s plumbing or return line. A properly sized and installed automatic pool ozone system can reduce the need for chemicals by 60 – 90%, saving both time and money.

The core of the DEL residential pool ozonator is the Corona Discharge (CD) electrode. This durable, highly reliable technology generates ozone by passing an electrical charge through one or more electrodes and forcing it into the pool plumbing or return line through an injector. The CD electrode supplants the UV ozone technology used in earlier ozonators, greatly increasing both the ozone output of the generator and its durability.

Ozone Systems in Pools

Ozone is most effective in pools when the sanitizer system is properly sized and installed. Pool ozone systems can be installed as either the primary sanitizer system or as a secondary system to supplement an alternative sanitizer.

Systems include several components and processes:

Ozone generator size: DEL ozonators are made to fit residential pools of 7,000 to 50,000 gallons when used as the primary sanitizer. It is possible to use multiple ozonators to generate enough ozone to sanitize larger pools. Ask DEL about your pool if you need a customized system.

Ozone injection: Ozone is injected into the pool water only when the filtration system is running. The water motion passing the ozone injector has to be very turbulent to force the greatest amount of ozone to dissolve. DEL recommends Mazzei components to ensure the maximum amount of effective ozone.

Filtration / pump cycles: Since ozone injection depends on turbulent water, it only happens when the pump is running to create the water flow. DEL recommends having the pump run a minimum of six hours per day.

Continuous ozone injection: DEL’s ozonators include a small built-in pump that runs quietly 24 hours per day independently of all other pool equipment. This continuous ozone injection, in effect, multiplies the effectiveness of a given size of ozonator. If a pool is equipped with a continuous circulation pump, an ozone generator can be installed on that line to achieve a similar effect.

Variable speed pumps: Energy concerns have led pool equipment manufacturers to develop pumps that can run a various speeds to minimize the amount of electricity used over a full day’s cycle. DEL’s ozonators can be installed with a specialized injector manifold that allows them to operate effectively at various pump speeds, allowing the ozone injection to happen at all pump speeds. No other manufacturer offers this sanitizer solution.
