Eliminates 99.9% of Microorganisms
Correctly sized systems destroy up to 99.9999% (6-log reduction) of microorganisms including viruses and pathogens.
Technology
Ultraviolet (UV)
Germicidal UV light that eliminates microorganisms without altering taste, colour or pH.
At a glance
What it removes
Bacteria, viruses and pathogens — up to 99.9999% (6-log reduction) of microorganisms.
Best for
Source water under 300 ppm TDS.
Key advantage
No chemicals, no moving parts, and no effect on the taste, colour or pH of water.
How It Works
The UV Process
-
Water Inlet
Water enters the UV chamber.
-
Quartz Sleeve
Protects the lamp while allowing UV light to pass through.
-
UV Exposure
Germicidal UV-C light at ~250 nm penetrates microorganisms.
-
DNA Disruption
UV scrambles DNA and RNA, preventing reproduction.
-
Safe Water Out
Microbiologically safe water, chemically unchanged.
In Detail
Overview
The UV Lamp
Ultraviolet radiation is emitted by very low pressure mercury vapour lamps, with a power rating up to 200 watts and an average lamp life between 7,000 and 8,000 hours. The wavelengths lie in the 200-300 nm range, with maximum microbicidal action around 250 nm.
How UV Sterilisation Works
UV sterilisation — also known as ultraviolet germicidal irradiation — works by breaking down chemical bonds and scrambling the structure of DNA, RNA and proteins, leaving microorganisms unable to multiply.

Why UV
Advantages of UV
No Internally Moving Parts
Self-contained systems with a replaceable UV lamp mean less wear and lower maintenance.
Compact Systems
UV technology is compact and non-intrusive, and can often be retrofitted to existing treatment systems.
Does Not Affect Colour or Taste
No effect on pH, taste, colour or smell, and nothing is added to the water.
No Chemicals
No chlorine or biocides required, meaning a safer working environment and fewer ongoing supply costs.
Flexible UV Intensity
Disinfection dose is determined by UV intensity, not system size; system size determines flow rate.
Excellent Efficiency
With a strong enough UV-C source, water can be completely disinfected in a single cycle.
