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 2.4Ahdm3 (vs. 11.4Ahdm3) and 12.5kWhm3 (vs. 75.0kWhm3) to completely mineralize 100mgdm3 of clopyralid spiked in a low-conductive (1mScm1) 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.
