Many environmental engineering processes require the adjustment of solution pH which has been historically achieved via acid/base addition. Recent research has explored electrochemical approaches to perform pH adjustment to improve the sustainability and logistics especially for distributed treatment system. Biopolar Membrane Electrodialysis (BMED) is one of such electrochemical approaches. In this presentation, I will give an overview of the working principle of BMED and discuss several interesting examples of its environmental applications. I will also present some progress we made in understanding the system performance of BMED and applying BMED for recovering nutrients from wastewater and source separated urine.
