Berson’s medium pressure
UV systems are being used in
a trial in the Netherlands to
treat hospital wastewater prior
to discharge. In the trial, UV
is applied in combination
with hydrogen peroxide
(H2O2) to generate OHradicals
in a so-called
Advanced Oxidation Process
(AOP). The very reactive OHradicals
attack the
pharmaceutical residues in
the wastewater, breaking them
down into H2O, CO2 and
harmless metabolites
Prior to UV/H2O2
treatment, the complete
wastewater stream is pretreated
in a membrane
bioreactor (MBR). The
wastewater then passes
through a Berson InLine
medium pressure UV system,
into which specific amounts
of H2O2 are injected. The
treated wastewater is then
discharged as treated sewage.
