Adavanced Electron Beam (EB) Wastewater Treatment System with Low Background X-ray Intensity Generation

Electron beam wastewater treatment is a very effective method for the destruction of
organic and microbiological pollutants. The technology was implemented for municipal and textile
industry wastewater treatment. Availability of electron accelerators characterized with different
operation parameters make the technology applicable for different end-users and also for installation
in confined spaces. In such a case, the design of wastewater irradiation room has to take into
account the limited space available for shielding construction, which must restrict X-ray emission.
Considering construction of an irradiation room for water treatment facility, it is important to focus
not only on a stream formation for irradiation to achieve the desired electron penetration, but also on
the reduction in x-ray generation. In the presented work, the X-ray field was tested, using modelling
and experimental methods. The final results gave an advanced solution, which can be used in the
installation of wastewater treatment, ballast and other types of origin, providing low cost shield and
good radiation protection measures.
