Emerging organic contaminants (EOC) are products or chemicals without regulatory status and whose effects on the environment
and human health are still unknown. Pharmaceuticals and personal care products (PPCPs) are recognized as â??emergingâ??
contaminants due to their bioactivity, wide usage, and potential health and ecological risks. The wide range of chemical properties
of PPCPs constraints the development of a universal technology for effluent cleaning in wastewater treatment plants (WWTPs). The
present work is part of an INTERREG SUDOE project, 4KET4REUSE, which one of the main objectives is to promote innovative
capabilities for water reuse promoting a sustainable growth. The electrokinetic (EK) technology is being studied by the team aiming
to optimize and to make it suitable as an effluent polishing step in WWTPs. The work here presented focused on the definition of the
best electrode materials and design aiming to improve PPCPs removal from the effluent. For that, metal mixed oxide coated titanium
(MMO) as a cathode was investigated with (i) different anode materials: graphite, platinized titanium (Pt/Ti) and MMO, and (ii) three
different shapes (bar, mesh and circular mesh). The EK experiments were carried out applying 0.3mA cm-2 of current for 2 hours. In
order to optimize the treatment, higher current intensities were also tested. In addition, the microbiologic community was analyzed
in the initial sample and after treatment. Differences in energetic costs between electrode materials and shape were also evaluated.
The results showed that the Pt/Ti bar and MMO mesh with circular shape had the best EOC removals ( E-mail: arl.ferreira@campus.fct.unl.pt Biography :
