Ultraviolet sterilization is the process of destroying all microbial life by means of ultraviolet radiation.[1]​.

Ultraviolet light or "UV" as it is usually referred to, is one of the proven means to treat biologically contaminated water, air or surfaces. This simple and safe technology is suitable for small residential flows, as well as large flows in commercial and industrial projects.

Water sterilization

The water we drink must be perfectly purified; for this, raw water must go through a complicated purification process, which in turn has many stages.

In water there are usually viruses, bacteria, spores, protozoa and molds that cause various diseases. For this reason, water refinement systems are constantly developing in order to improve health.

Disinfection of liquids using ultraviolet light has many advantages, since it does not leave residues and does not alter its composition or properties as other chemical treatments do.

The most common application consists of placing a UV filter in a section of the duct through which the liquid circulates. As it is a part of the process, no extra time is invested in special treatments or intermediate steps.

These UV filters intercept and inoculate germs as they pass through ultraviolet light; In addition, UV radiation destroys algae and protozoa and thus disables their expansion and contamination.

Air sterilization

There is always the risk of contamination by microorganisms that use air as a means of transport, and that cause respiratory diseases in people and/or rapid putrefaction of products in industries.

The microorganisms are aspirated by the equipment, where depending on the dose used and the exposure time, up to 99.9% is eliminated through the application of short-wave ultraviolet rays (UV-C).

Surface sterilization

Ultraviolet surface sterilization systems are used mainly in the food industry to sterilize production media such as conveyor or sorting belts, packaging machines, fermentation containers, as well as sheets and closing lids.

The invasion of the means of production by microorganisms is most of the time inevitable, often causing a notable reduction in their shelf life when they come into contact with food products, and may also represent a risk to the health of consumers.

The surfaces of the production media are treated with short-wave ultraviolet rays (UV-C), reaching sterilization percentages of up to 99.9% depending on the dose.

The possibility of creating ultraviolet sterilizers is being studied to disinfect surfaces such as kitchens "Kitchen (room)") or bathrooms, since they are capable of annihilating all kinds of pathogenic microorganisms that also cause bad odors.
