Ozone Generator (O3 Generator)

An ozone generator produces ozone (O₃) from ambient air using corona discharge or UV radiation technology. In hot tubs, cooling tubs, and small pools, ozone injected through a Venturi injector dissolves in the water, where it acts as a strong oxidising agent. Ozone reacts with bacteria, viruses, moulds, and organic contaminants, breaking them down chemically. Unlike chlorine, it leaves no lasting residual effect – after reacting, it decomposes back into oxygen. It is a supplementary disinfection system that reduces the load on the primary chemistry. Correct effectiveness depends on mixing, contact time, and water quality.

Advantages of an ozone generator

• Significantly lower chlorine or bromine consumption: Ozone oxidises organic contamination before it breaks down into by-products, reducing the required dose of disinfection chemicals.
• Higher clarity and less water odour: Breaking down organic contaminants such as sweat, oils, and cosmetics reduces cloudiness and the typical chemical smell of the water.
• Faster breakdown of microorganisms than chlorine: Ozone is a strong oxidising agent and, with correct contact with the water, acts faster than standard chlorine disinfection.
• No chemical residue after reaction: Ozone decomposes back into oxygen after it acts, leaving no long-persisting by-products in the water.
