Nanoparticles for water treatment and stabilisation

With the changing climate, the issue of suitable management of waters in the Czech Republic may belong under the priorities of interest of the entire society. One of the possibilities of safe utilisation of drinking or process water (rainwater, recycled water) is the increasing of its stability and quality by means of products containing nanoparticles of silver (Ag). In collaboration with New Human Solution s.r.o. (NHS s.r.o.) we developed an original method for preparing selected substrates with Ag nanoparticles fixed to their surface. The substrates are artificial or natural carriers with particle size ranging from microcrystalline powders to rough particles, depending on the method and type of application. The high-surface substrates, mainly in combination with photocatalytic TiO2, are suitable for preparing original porous coatings facilitating technical solutions of flow water treatments.

At the moment, ÚACH prepares these materials under other activities and part of the profit is used for further development of materials under applied ÚACH research, as the broad possibilities of the preparation of the above products and their application require permanent innovative approach. The know-how of the preparation of the above products is the property of ÚACH and it is protected as registered know-how in ÚACH register. With respect to collaboration and introduction of the products on the market by NHS s.r.o., this company holds the exclusive right for commercial use of these products. NHS s.r.o. is also the exclusive holder of certificates for the use of the products in the given applications. Potential transfer of know-how for the production of the materials to NHS s.r.o. will take place by means of an exclusive license agreement on the condition of minimum permanent volume of production and providing of technical support. The company is interested in buying the know-how.
