Ozone and Ozone/UV radiation
for water treatment using a Dielectric Barrier
Discharge (DBD) coupled to an Oscillatory
Baffled Reactor (OBR)
Ozone is well recognized as a strong oxidant in
water and waste water treatments due to its high
oxidation properties and capability for removing
a wide range of chemical and biological
contaminants. However, the main shortcoming of
ozone is its low solubility in water which
limited the extent of its applications. The aim
of this research is to characterize and optimize
an Oscillatory Baffled Reactor (OBR) for
ozone-water dissolution. The characteristic
study will be looking at the effects of
operational conditions such as superficial
velocities of input gas and liquid, oscillation
conditions and reactor arrangement on gas
hold-up and volumetric mass transfer
coefficient.
The optimized system will be coupled with
a UV radiation source to be used for water
treatment.
