Abstract:<\/p>\n

The need for better microplastic removal from wastewater streams is
\nclear, to prevent potential harm the microplastic may cause to the
\nmarine life. This paper aims to investigate the efficacy of
\nelectrocoagulation (EC), a well-known and established process, in the
\nunexplored context of microplastic removal from wastewater streams. This
\npremise was investigated using artificial wastewater containing
\npolyethylene microbeads of different concentrations. The wastewater was
\nthen tested in a 1 L stirred-tank batch reactor. The effects of the
\nwastewater characteristics (initial pH, NaCl concentration, and current
\ndensity) on removal efficiency were studied. Microbead removal
\nefficiencies in excess of 90% were observed in all experiments, thus
\nsuggesting that EC is an effective method of removing microplastic
\ncontaminants from wastewater streams. Electrocoagulation was found to be
\neffective with removal efficiencies in excess of 90%, over pH values
\nranging from 3 to 10. The optimum removal efficiency of 99.24% was found
\nat a pH of 7.5. An economic evaluation of the reactor operating costs
\nrevealed that the optimum NaCl concentration in the reactor is between 0
\nand 2 g\/L, mainly due to the reduced energy requirements linked to
\nhigher water conductivity. In regard to the current density, the
\nspecific mass removal rate (kg\/kWh) was the highest for the lowest
\ntested current density of 11 A\/m2, indicating that low current density
\nis more energy efficient for microbead removal.<\/p>\n
