The Technology


Puralytics’ ® core technology is a proprietary catalyst material, an assembly of nanoparticles that purifies water without being degraded.  It can be used multiple times minimizing waste and disposal problems associated with physical water treatment technologies which collect contaminants instead of breaking them down. 

Our products purify water using multiple photoactivated processes.


Puralytics’ core process is photocatalysis, activation of our catalyst material with high energy light, in the UV range, generating electron/hole pairs. These charges react with water to break down contaminants and disinfect.

The hole interacts with water to form highly reactive hydroxyl radicals (·OH) in a process generally referred to as photocatalytic oxidation. This radical is a powerful oxidant and interacts with carbon bonds in any organic contaminants breaking them down. The electron participates in reduction reactions with oxygen or directly with contaminants.  Reactive oxygen species (ROS) are formed, which in turn, can participate in oxidation reactions.

The hydroxyl radical and ROS are highly effective at breaking down organic contaminants. Similarly, the hydroxyl radical and ROS will interact with microorganisms.  The interaction results in fatal damage to the microorganisms due to disruption of cell membranes, DNA and RNA. With photocatalysis, the final products of degradation are carbon dioxide, water and respective salts from the broken down contaminants.


Photolysis is the absorption of photons with sufficient energy to directly dissociate chemical bonds. Shorter wavelengths are highly energetic and effective over a wide range of chemical bonds.  Wavelengths between 200 and 300 nm are categorized as germicidal or able to inactivate microorganisms such as bacteria, viruses and protozoa.

Puralytics’ products employ wavelengths in the ultraviolet (UV) range that interact with chemicals and pathogens in water directly. This mechanism of deactivation disrupts cellular RNA and DNA rendering the microorganism incapable of reproduction or infection.
