E!8921 A photocatalytic unit for water cleaning using UV-LED and doped catalysts applied to ballast water

Photocat aims to develop a new water decontamination unit combining novel, doped nanophotocatalysts with UV-LEDs in a system that completely destroys chemical & microbiological contaminants without producing harmful by-products. Photocat will deliver a prototype of a novel decontamination system, optimised for ballast water cleaning, including a clear demonstration of the system. This can be in addition to current technologies, or as a replacement for conventional UV water treatment. An extensive testing of the photocatalyst has been performed and the photocatalyst has been optimized for production of radicals. The pilot-demo system has been designed an produced, and testing has been performed. The results show that the photocatalytic process is functioning very well with the developed catalysts, generating effectively radicals being used to destruct both microorganisms and chemical compounds. However, the test equipment turned out to be too small to be able to test destruction of impurities in ballastwater efficiently. Nevertheless, the obtained data are so promising that further development of this technology will be continued. Photocat is a Cooperative Project With 3 Norwegian partners (KeraNor, NIVA and NTNU) and 2 British partners (P.W.Circuits and Axess).
