Safe Water Storage through Inorganic Coatings
Ensuring microbiological stability in stored water is essential for both public infrastructure and emergency systems. Our team has developed inorganic powder-based coatings that are applied to the inner surfaces of storage tanks and reservoirs. These materials:
• Prevent microbial contamination,
• Maintain long-term water stability,
• Are safe, durable, and non-toxic.
They are based on modified inorganic matrices with antibacterial properties, tailored to minimize biofilm formation and resist water-borne pathogens.
Certified for Use in Drinking Water Applications
Our coatings have been:
• Rigorously tested for safety and efficacy,
• Certified by the Czech National Institute of Public Health,
• Successfully licensed for industrial production and use.
These materials meet strict requirements for contact with drinking water, and their performance has been validated under long-term real-world conditions.
Photocatalytic and Antibacterial Functional Surfaces
In parallel, we also develop advanced functional coatings that utilize:
• TiO₂ nanoparticles for photocatalytic degradation of organic compounds,
• Silver nanoparticles for broad-spectrum antibacterial activity.
These coatings can be applied to metal, polymer, or ceramic surfaces (e.g., steel) to create:
• Self-cleaning,
• Disinfecting,
• Low-maintenance water-contact surfaces.
Such materials are suitable for use in water treatment systems, filtration units, and infrastructure exposed to environmental contamination.

Sustainability and Strategic Relevance
Our water treatment technologies support:
• Clean water goals under EU environmental policy,
• Reduction in chemical additives for disinfection,
• Improved water quality and public health,
• Application in both domestic and industrial contexts.
They offer a robust, non-biocide-based alternative for systems where long-term performance and safety are key.
