Development of a mobile unit with an
electron beam accelerator

Nowadays, the Radiation Technology Cen-
tre is involved in establishing a mobile unit
with an electron beam accelerator to treat
industrial effluents for reuse purposes (FIG.
5). The mobile unit will be equipped with
an electron beam accelerator (0.7MeV and
20kW) with safety requirements (BSS, IAEA
and CNEN Safety Standards), and can be used
for treatment of effluent from petroleum pro-
duction, for petroleum desulfurization, and,
in addition, for degradation of toxic organic
compounds in wastewater for reuse. This
project is supported by the IAEA (TC Project
BRA1035 - 2016-2018) and by the Brazilian
Financial of Studies and Projects (FINEP). To
