Hyeongrak Cho is a water treatment expert and researcher at Kookmin University's Smart Water Environment Leading Laboratory (SWELL). Born in 1986, Cho obtained his Ph.D. in Environmental Engineering from Kookmin University in Seoul, Korea, in September 2019. During his graduate studies, Cho focused his research on the treatment of water, wastewater, and desalination using membranes. In particular, he developed expertise in the treatment of highly concentrated salt wastewater, publishing a paper entitled "Effect of pre-treatment and operating conditions on the performance of membrane distillation for the treatment of shale gas wastewater" in Desalination (IF 6.035). Cho has conducted two successful projects on the treatment of highly concentrated wastewater. The first involved treating shale gas wastewater generated in Texas using the membrane distillation technique, and the second involved treating highly concentrated desalinated seawater using a semi-pilot MD instrument. Manuscripts from these projects are currently being submitted to high-impact water treatment journals. Cho's experience also includes knowledge of MF/UF, coagulation, and sedimentation for pre-treatment and chemical, physical, and ultrasonic washing for post-treatment. He has collaborated on desalination projects involving forward osmosis (FO), reverse osmosis (RO), reverse electrodialysis (RED), and capacitive deionization (CDI). In addition to his research, Cho is studying modeling for the automation of water treatment plants using Cyber-Physical Systems (CPS), Life Cycle Assessment for decreasing Carbon emission, Computational Fluid dynamics, and pipe analysis and design for Ultra pure water supply. Cho believes that his strong understanding of general and next-generation water treatment techniques and his experience in pilot operations make him a valuable asset to any research project.
