The need to have pure water, without bacteria, made it necessary to implement the study of new solutions, that have low environmental impact: the uv sterilizer is the ideal solution. In fact, this allows to eliminate bacteria in a natural way, through the use of ultraviolet rays (UV-C), thanks to their capacity to disrupt the DNA and the RNA of microorganisms, by turning them inactive.

The UV sterilizers enables to eliminate chemical treatments, by cleaning the water from external agents and bacterial contamination and making it usable in its purest form.

SATEPA Srl produces a wide range of uv sterilizers with flow rates going from 0 to a max of 93 m³/hr, in stainless steel or in HDPE, and with the help of its proprietary designed electronics devices, applied to uv systems, it allows to have a uv water sterilizer at a very high efficiency and low environmental impact.


DOMESTIC installations often require to remove micro-organisms and bacteria, such as Cryptosporidium and Giardia lamblia, which have a high resistance to chemical disinfectants. However, with UV systems the DNA-RNA of bacteria is destroyed, and water is made reliable for human use.

Also in POINT OF USE applications, water must be the purest possible, without micro-organisms, bacteria, legionella: the UV system process is often needed to killl bacteria and make water useful for human use.

MUNICIPAL water is often affected by legionella, which can be easily eliminated with UV sterilizers, that can also remove pathogenic micro-organisms harmful for humans, by inactivating them and making the water microbiologically pure and uncontaminated.

INDUSTRIAL applications, many times, require the use of water free from bacteria and viruses, depending on the process, but obtainable with UV sterilizers that can decrease, sharply, the contamination of the used material.


UV sterilizers in POOLS enable for the decrease in the amount of chloramines limiting the use of chlorine and other chemical substances responsible of red eyes or irritation of the skin. It can also inactivate bacteria, viruses and other pathogens for a better water where to swim.

Similarly, the combined chlorine that is inevitably generated is eliminated with the use of sterilizers thanks to the emission of UV-C radiation

WASTE WATER is one of the factors that increase the pollution of the planet, and UV systems, properly dimensioned, are the most important part in the treatment process, where, after filtering, the bacteria charge has to be inactivated. With UV, it is also possible to undergo an oxidation process to reduce toxic pollutants.

AQUACULTURE is affected by pathogen problems, both in fresh and sea water, fixed with UV disinfection systems. As it is not harmful for fish, no chemical products are needed for the treatment. As a result, with a correct dimensioning of the systems 99.99% of bacteria are inactivated.


CORROSIVE and CHEMICALLY AGGRESSIVE WATERS are present in many industrial processes and in the process of water purification on ships or in sea pools. It is therefore essential to use corrosion-free appliances, such as high-density polyethylene, which does not deteriorate with UV rays.

In the AQUACULTURE industry, due to the presence of brackish water, the use of polyethylene sterilizers is necessary to ensure a long-lasting debacterization without the deterioration of the equipment used.
