A microfluidic flow-through electrochemical reactor for wastewater treatment: A proof-of-concept

A microfluidic flow-through electrochemical reactor for wastewater treatment: A proof-of-concept
In this work, a microfluidic flow-through electrochemical reactor for wastewater treatment is presented which simultaneously minimizes ohmic drop and mass transfer limitations, two of the most important bottlenecks in electrochemical wastewater treatment. A proof-of-concept comparison versus a state-of-the-art flow-by commercial reactor revealed that the proposed reactor greatly outperforms the commercial system. The novel system requires only 2.4Ahdm−3 (vs. 11.4Ahdm−3) and 12.5kWhm−3 (vs. 75.0kWhm−3) to completely mineralize 100mgdm−3 of clopyralid spiked in a low-conductive (1mScm−1) matrix with both systems using diamond anodes. The microfluidic flow-through configuration represents a promising approach to the development of cost-effective electrochemical technologies for wastewater treatment.
