How Corona Discharge Ozone Sanitises Pool Water
Ozone is a powerful and natural sanitiser, and when generated using corona discharge (CD) technology, it becomes a highly effective way to purify pool water without relying solely on chlorine or other chemicals.
✅ What Is Corona Discharge Ozone?
Corona discharge is a method of generating ozone (O₃) by passing oxygen (O₂) through a high-voltage electrical field. This electrical energy splits oxygen molecules into individual atoms, which then recombine with other oxygen molecules to form ozone.
O₂ + Energy → 2O
O + O₂ → O₃
CD ozone generators are popular because they:
Produce a higher concentration of ozone
Are more energy-efficient
Have a long lifespan with minimal maintenance
✅ How Ozone Sanitises Pool Water
Once introduced into the pool system (usually injected into the return line via a venturi or injector), ozone immediately begins to oxidise and destroy:
Bacteria
Viruses
Algae
Organic contaminants like body oils and lotions
Ozone is up to 3,000 times faster and 50 times more powerful than chlorine at killing certain pathogens. It works by breaking down cell walls and disrupting the DNA of microorganisms.
✅ Benefits of Corona Discharge Ozone for Pools
Chemical Reduction: Significantly lowers chlorine usage, reducing skin/eye irritation and chemical smell
Cleaner, Softer Water: Water feels silkier and looks clearer
No Residual Byproducts: Ozone breaks down into oxygen, leaving no harmful residues
Eco-Friendly: Reduces the number of chemicals entering the environment
⚠️ Important Notes
Ozone is a point-of-contact sanitizer, meaning it works in the ozone chamber or mixing zone, but doesn’t leave a lasting residual in the pool. A small amount of chlorine or other residual sanitiser is usually still required.
Proper installation and maintenance of the ozone system are essential for optimal effectiveness.
