Professor Sungjun, Bae of the Department of Civil and Environmental Engineering from Konkuk University’s College of Engineering and Professor Khalil Hanna from ENSCR(Ecole Nationale Supérieure de Chimie de Rennes) in France have developed environmental catalyst technology to remove micropollutants in pathogenic wastewater. The result of the research, which was conducted as a joint international study, was published in the international journal ‘Water Research’, which ranksd first in JCR ranking (if 9.130) among 94 SCI(E) journals in the field of water resources.

The research team of Professor Bae of Konkuk University has developed the world’s first technology to decompose and remove micropollutants (antibotics), which may exist in pathogenic wastewater, by using industrial waste called ‘red mud’ from aluminum industry. 
According to the report released by World Health Organization (WHO) in 2017, issues on antibiotics resistance are considered one of the biggest global threats to health, food security and development, and are frequently detected in hospitals and urban wastewater. 
The research team suggested an economical technology that can promote oxidative decomposition and remove antibiotics from pathogenic wastewater by using red mud, which is generated about 132 to 264 million tons annually in the global aluminum industry causing environmental issues, as an environmental catalyst. Based on the previous report, red mud has been considered to have limitations in that its processing time is way too long or UV should be tested to be used as an environmental catalyst for wastwewater treatment in AOP(Advanced Oxidation Process) despite its confirmed possibility as an adhesive for cement additives, dyes and heavy metals. The research found out that red mud can be used along with Preoxymonosulfate(PMS) and Hydroxylamine in order to effectively oxidize and remove antiobiotics from pathogenic wastewater by facilitating the circulation of Fe(III)/Fe(II) of iron oxides contained on the surface of red mud. 
Professor Bae stated, ‘The finding has such an economical advantage as we can efficiently decompose and remove antibiotic substances from pathogenic wastewater without having to investigate the treatment and reforming process of red mud or UV.” adding, “We can present practical technologies that can be newly applied in highly advanced oxidation processes for various water-soluble wastewater treatment.” 
Joohyun Kim, a graduate researcher at Konkuk University, and Gnougon Nina Coulibaly, a researcher from France’s ENSCR, who has conducted the research as an exchange student at Konkuk University for two months, participated in the thesis sharing co-first authorship. Along with them, Sunho Yoon, a Ph.D. researcher at Konkuk University has also co-authored the thesis. Professor Bae and Professor Khalil Hanna of ENSCR have taken part as joint authors. The research was supported by Ministry of Science and ICT with International Joint Research Project and Basic Research Project between Korea and France.
