- A new microfluidic flow-through reactor design is proposed.
- Electrochemical reactor with low ohmic resistance and high mass transport
- The proposed design clearly outperforms a commercial flow-by reactor.
- Four times higher efficiency and six times lower energy consumption is achieved.
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 2.4 Ah dmâ 3 (vs. 11.4 Ah dmâ 3) and 12.5 kWh mâ 3 (vs. 75.0 kWh mâ 3) to completely mineralize 100 mg dmâ 3 of clopyralid spiked in a low-conductive (1 mS cmâ 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.
