Ozone and hydroxyl radicals combine to produce powerful sanitiser
Waterco has launched its new Hydroxzone Ozonator, one of the most powerful sanitisation systems on the market. The Hydroxzone is one of the key components of Waterco’s new Hydroxypure chlorine-free pool system, and it’s designed as a standalone product for both new and existing swimming pools.
“The Hydroxzone Ozonator uses hybrid patented technology to produce not only ozone but also hydroxyl radicals, which, combined, add another level of effectiveness in terms of oxidation and sanitation,” says Victor Quijada, Waterco’s water treatment product manager.
Waterco’s Hydroxzone system uses a modified VUV (high intensity ultraviolet light) ozone tube as a corona electrode to simulate nature (hybrid ozone acts like the sun). The result is an ozone generator that produces ozone using corona discharge technology and high energy light in one system.
“The combination also catalyses Advanced Oxidation Processes (AOPs) and, as a result, hydroxyl radicals are generated,” Quijada explains. “Put simply, hydroxyl radicals are typically formed when UV rays break up ozone and water droplets and then recombine. Scientists have dubbed hydroxyl radicals as the ‘detergent of the atmosphere.’”
The main benefit of the system is an additional ‘layer’ of sanitisation, Quijada says.
“Ozone, which is found in nature, kills microorganisms, destroys organics and breaks down chloramines by oxidation. It’s highly effective in reducing and destroying chloramines in the water
“In addition, ozone provides micro-flocculation to aid filtration and noticeably improve water clarity. It also destroys biofilm and reduces the amount of chlorine consumption while maintaining Free Available Chlorine (FAC) residual.”
Wateco’s Hydroxzone Ozonator can be used in pools with manual or automatic chlorine dosing and also with salt chlorinators.
“The ozone will contribute to the sanitisation process by reducing the chlorine demand,” Quijada explains. “In some states – e.g. South Australia – pool owners ask for installation of an ozonator to run their pool at lower chlorine levels, with the peace of mind that their pool is safe.”
There are a number of key benefits of the Hydroxone system:
- It produces pure ozone (there are no toxic nitrous compounds as found in standard corona discharge ozone generators)
- Output is constant and not negatively affected by temperature or humidity as with standard corona discharge technology
- It produces hydroxyl radical, one of the most powerful oxidisers found in nature
- There are no moving parts, which makes maintenance easy
- It’s easy to install and comes with a bypass kit
- Can be used on new pools or easily retrofitted to existing pools
The Hydroxzone uses a Dynamic Venturi Injector, whereby the pool water is mixed with the ozone/air mix at the throat of the injector through a narrow annular orifice, thus creating very small bubbles. This method of delivery allows the bubbles to be sustained in the water, maximising the efficiency of the ozone mass transfer.
Key features of the Dynamic Venturi Injector include:
- ASME injector flow configuration to minimise pressure drop
- Built in restriction at the orifice to increase the injection velocity and maintain constant frothing ratio
- Adjustable 360°annular injection orifice
- Dual injector point
- Internal premixes cavity for dual ports
- Rugged construction
