2 TA Technology Agency of the Czech Republic The use of photoactive nanosurfaces to solve current problems of air and water cleaning The main aim of the project is to design and manufacture three devices for deep cleaning of air or water using photocatalysis. The functionality of the products will be tested using the methods set out in adopted or proposed international standards. The complex impact of these devices on the environment will be evaluated in the range of concentrations of pollutants that correspond to real values in the environment. The objectives will be: 1. Pilot production of heating panels with dual functions i.e. cleaning the air. Construction of attestation equipment. Cooperation with the company RETAP. 2. Construction of prototype equipment for removing interior odors such as sports shoes and comprehensive testing of its impact on the environment in living rooms. Industrial protection of the product (utility model). 3. Design of a technology and prototype equipment for wastewater purification for capillary radiograph lines. Patent protection of the product and its testing under real conditions with real waste. Cooperation with the company ATG.

15 Conclusions: 1.Heat transfer surface of the heat exchanger, which can be used for both heating and cooling, plays simultaneously role of photocatalytic surface. 2.In its interior there is a purification of the circulating air on the principle of photocatalysis, suppression of bacteria and viruses as well as removal of odors and toxic gases. The advantage compared with conventional purifiers with different types of filters is that the photocatalytic process completely demineralized bacteria and viruses, and so there is no so-called secondary pollution due to the filters, loosening the dirt from the filter back into the surrounding environment. 3.The photocatalytic layer can be deposited on various non porous supports, like glass, ceramics, aluminium, 4.Thanks to the construction of the lamellae, very high area for TiO2 deposition is accessible. 5.Construction of the apparatus enables 100% illumination with následným 100 UVA radiation.
