Title: Innovations of Siwon Choi in Water Treatment Technologies
Introduction
Siwon Choi is an accomplished inventor based in Cambridge, MA (US). He has made significant contributions to the field of water treatment technologies, holding 2 patents that showcase his innovative approach to solving complex environmental challenges.
Latest Patents
One of Siwon Choi's latest patents is the "Ion concentration polarization-electrocoagulation hybrid water treatment system." This invention utilizes two juxtaposed similar ion exchange membranes (AEMs or CEMs) to create an ion depletion zone and an ion enrichment zone under an electric field. As cations are selectively transferred through the CEMs, anions are relocated to maintain electro-neutrality, resulting in a concentration drop in the ion depletion zone and an increase in the ion enrichment zone. The incorporation of a sacrificial metal anode allows for electrocoagulation (EC) to occur concurrently with ion concentration polarization (ICP), enabling the simultaneous concentration of both ionic and non-ionic impurities within the same cell or device.
