Photovoltaic system for the treatment of surface water polluted with polycyclic aromatic hydrocarbons in Colombia
...
Rubio Clemente, Ainhoa | 2018
Due to the development limitations of remote and
non-interconnected zones related to the access to safe drinking
water and taking into account the high electrical costs associated
to the application of advanced oxidation processes (AOPs) for
decontaminating water, the utilization of a photovoltaic (PV)
array supplying the electrical needs of the technologies involved
in the water treatment might be an alternative option. In this
way, the current study presents the feasibility of using a PV
array without batteries coupled to a UV/H2O2
system to treat
surface water from a Colombian reservoir polluted with ultratrace levels of polycyclic aromatic hydrocarbons. Very
promising results were obtained, with removal efficiencies near
100% and without the formation of by-products more dangerous
than the parent contaminants. The results were comparable to
those ones obtained using the conventional electrical grid.
Consequently, the PV array evaluated allows the sustainable
decontamination of pollutants in surface water persistent to
traditional water treatments, with the subsequent production of
drinking water, providing the accomplishment of other regulated
parameters, in remote and non-interconnected areas, which are
particularly important in developing countries, such as
Colombia.
