Pyung-Kyu Park 교수의 연구실은 수처리 및 막 기반 정수 기술에 초점을 맞추고 있으며, 특히 역삼투막 및 막 생물반응기(MBR)에서의 생물막 형성과 그 제어를 핵심 연구 주제로 삼고 있습니다. 고분자 기반 막 설계, 그래핀 옥사이드를 활용한 고포화 구조의 정밀 제어, 그리고 박테리아를 이용한 쿼orum 쿼칭 기반 생물막 억제 기술을 통해 수질 오염 제거 및 시스템 안정성을 향상시키는 데 기여하고 있습니다. 특히 저온 환경에서의 효율성 저하 문제를 해결하기 위한 박테리아의 환경 적응 기술 개발도 중요한 연구 방향입니다.

Incorporation of single-layer graphene oxide into a highly porous support layer provides a thin-film composite reverse osmosis membrane with superior water flux.
Bacterial quorum quenching (QQ), whose mechanism involves the degradation of quorum-sensing signal molecules, is an effective strategy for controlling biofouling in membrane bioreactors (MBRs). However, MBRs operated at low temperatures, either due to cold climates or seasonal variations, exhibit severe deterioration in QQ efficiency. In this study, a modified culture method for <i>Rhodococcus</i> sp. BH4, a QQ bacterium, was developed to induce environmental adaptation in cold regions. BH4-L, w
The support layer of RO membranes can significantly affect the permeability depending on its sublayer structure.
For removal of arsenic in the aqueous phase, hydrous iron oxides (HIOs) were immobilized in alginate beads with enhanced porosity (designated as HIO-P-alginate beads).
Lab-scale membrane bioreactors (MBRs) were investigated at 12, 18, and 25 °C to identify the correlation between quorum sensing (QS) and biofouling at different temperatures. The lower the reactor temperature, the more severe the membrane biofouling measured in terms of the transmembrane pressure (TMP) during filtration. More extracellular polymeric substances (EPSs) that cause biofouling were produced at 18 °C than at 25 °C, particularly polysaccharides, closely associated with QS <i>via</i> th
Membrane wetting in membrane distillation was accelerated by inorganics and hydrophilic organics. The wetting by ozonated humic acids was enhanced with an increase in the ozone contact time.
