Founded in 1991 in Gera, Germany, UST GmbH has been at the forefront of sustainable hygiene solutions across Germany and beyond for more than three decades. Our pioneering work in UVC technology began with the launch of our first brand, PURE WATER, in 2004—now a trusted leader in the sterilization of drinking waterusing ultraviolet light and ozone. Building on this success, we introduced ULTRA V in 2018, delivering a powerful and environmentally friendly solution for large-scale industrial water sanitization.

Today, our technologies are relied upon throughout Europe, with more than 15,000 systems installed and a reputation for quality, innovation, and reliability. As we continue to grow, we are proud to expand our global footprint through new joint ventures with partners in Senegal and Ghana, bringing our expertise to even more communities worldwide.

With the support of our partners and employees, we see ourselves as a leading organisation in the development of water disinfection systems tailored to the specific needs of diverse communities. As water disinfection becomes increasingly essential—today and for the future—our mission is clear: to provide effective, chemical-free solutions. We produce advanced disinfection systems powered by ultraviolet radiation and ozone, complemented by professional guidance from our team of experts.

Our systems offer:

1. Pure, safe water – naturally disinfected : A high-performance UVC lamp, housed within a premium stainless-steel reactor, emits light at 254 nm to instantly neutralise bacteria, viruses, and other microorganisms. This process ensures disinfection rates of up to 99.99%.

    

2. Safety first : The entire treatment takes place within our specially engineered reactor, eliminating the risk of overdosing and leaving no residues behind. The result is crystal-clear, perfectly safe water that maintains its natural purity.

    

3. Eco-friendly, efficient, and reliable : UVC disinfection works in a fraction of a second, delivering a sustainable, energy-efficient alternative to chlorine and other chemical treatments.

We believe that clean water is a vital resource that must be accessible to everyone. For more than 20 years, we have been developing and manufacturing high-quality UVC systems to bring this mission to life. Our commitment to expanding access to safe drinking water has carried us from Germany to Africa (read more about our projects in Africa here). We have established strong partnerships in Senegal and Ghana, where we aim to build long-lasting joint ventures that will strengthen local water infrastructure for years to come.

Production of UVC water disinfection systems

Through the development of water disinfection systems based on ultraviolet radiation and ozone, we actively contribute to reducing the use of chemicals in water treatment. In doing so, we help prevent environmental pollution and the emergence of resistant germs. Our ambition is clear: to produce the most reliable, effective, and user-friendly UVC water disinfection systems on the market.

With our PURE WATER systems, we inspire private users by proving that environmental protection and superior water quality can go hand in hand. Water treated with PURE WATER is safely disinfected without any changes in taste or odour—pure, natural, and germ-free.
