abstract = "In this work, a new coating of boron-doped diamond
ultra-nanocrystalline (U-NBDD), tailored to prevent massive
formation of perchlorates during disinfection, is evaluated as
electrode for the reclaiming of treated secondary wastewater by
the electrochemically assisted disinfection process. Results
obtained are compared to those obtained by using a standard
electrode (STD) that was evaluated as a standard in previous
research showing outstanding performance for this application.
First tests were carried out to evaluate the chlorine speciation
obtained after the electrolysis of synthetic chloride solutions at
two different ranges of current densities. Concentrations of
hypochlorite obtained using the U-NBDD anode at 25 mA cm\−2
were 1.5-fold higher, outperforming STD anode; however, at 300 mA
cm\−2, an overturn on the behavior of anodes occurs where
the amount of hypochlorite produced on STD anode was 1.5-fold
higher. Importantly, at low current density the formation of
chlorates and perchlorates is null using U-NBDD. Then, the
disinfection of the real effluent of the secondary clarifier of a
municipal wastewater treatment facility is assessed, where
inactivation of Escherichia coli is achieved at low charge applied
per volume electrolyzed (0.08 A h L\−1) at 25 mA
cm\−2 using the U-NBDD. These findings demonstrate the
appropriateness of the strategy followed in this work to obtain
safer electro-disinfection technologies for the reclaiming of
treated wastewater.",
