How Ozone Generators Work for Pharmaceutical Water System Disinfection
Ozone is a powerful disinfectant used in pharmaceutical water purification. Here’s how it works and why it’s effective.
How Ozone is Made
Ozone generators create ozone gas from oxygen. They use electricity or UV light to split oxygen molecules. These split molecules then form ozone.
How Ozone Kills Microbes
Ozone works in two ways:
-
It attacks and breaks down microbe cell walls
-
It destroys their DNA/RNA
This double action kills bacteria, viruses, and other contaminants effectively.
Key Advantages for Pharmaceutical Water
-
Strong disinfection: More powerful than chlorine
-
No chemical residue: Breaks down to oxygen, leaves no toxic byproducts
-
Penetrates biofilms: Reaches hidden microbes in pipes
-
Validatable: Easy to measure and control
How It’s Used in Pure Water Systems
-
Ozone is added to storage tanks
-
It circulates through the entire piping system
-
After contact time, it breaks down naturally
-
UV lights help remove leftover ozone
Why It’s Reliable
-
Works at low temperatures
-
Effective against resistant pathogens
-
Compatible with stainless steel systems
-
Supports GMP compliance
Safety Notes
Ozone levels must be monitored carefully. Proper venting and destruct systems are essential for operator safety.
For pharmaceutical water systems, ozone provides effective, chemical-free disinfection that meets strict quality standards.
