Project NANORADI (Advanced technologies of hygienical and toxicological security of outlet from WWTPs)

The main objective of the project is the development and application of innovative technologies for toxicological and hygienical security of treated municipal wastewaters using zero-valent iron nanoparticles, respectively materials releasing hydroxyl radicals. Toxicologically and hygienically secured outlets from municipal WWTPs represent a huge potential in the recycling of treated wastewaters.

ASIO company has a role of coordinator in the project. Among other solvers include RAWAT consulting, s.r.o., which is a representative of a small business and The Institute of Botany of the ASCR and Palacký University Olomouc, which are the representatives of academia. The Institute of Botany of the ASCR and ASIO collaborate on another research project related to nanotechnology, but with UPOL and RAWAT this is the first collaboration in research and development.

Iron materials are supplied by Czech company NANO IRON, which produces zerovalent iron nanoparticles for groundwater remediation and laboratory purposes. NZVI is supplied in powdered form or in aqueous suspension. Strong reactive aqueous suspension of pyroforic powdered NZVI (trade name NANOFER 25) is applied in the tests. Zerovalent iron nanoparticles are stabilized by inorganic modifiers. The content of zerovalent iron nanoparticles in the suspension is in the range of 16 to 18 wt.%.

A key outcome of the project will be utility model of the reactor adapted for nanoiron particles application, and the separator of unreacted zero-valent iron, which is used for the effective separation of zero-valent iron particles (NZVI) from cleaning. Project results are and will be presented to the general public at conferences (eg NANOCON) and in professional press.
