김우치 교수의 연구실은 막 생물반응기(MBR) 및 직접막여과(DMF) 기반의 폐수처리 기술에 초점을 맞추고 있으며, 특히 막 혼탁화의 원인과 제어 기반의 지속가능한 운영 전략을 연구하고 있습니다. 유기물의 성질과 막 재질 간의 상호작용이 불가逆한 혼탁화에 미치는 영향을 체계적으로 분석함으로써, 실질적인 운영 비용 절감과 장기 안정성 확보를 목표로 하고 있습니다. 특히 화학적 역세척(CEB) 기술과 고도정화 기반의 막 재생 전략 개발에도 주력하고 있습니다.

The main obstacle for wider use of membrane bioreactors (MBRs) for wastewater treatment is membrane fouling (i.e., deterioration of membrane permeability),which increases operating costs. For more efficient control of membrane fouling in MBRs, an understanding of the mechanisms of membrane fouling is important. However, there is a lack of information on membrane fouling in MBRs, especially information on features of components that are responsible for the fouling. We conducted a pilot-scale expe
The elimination of six acidic pharmaceuticals (clofibric acid, diclofenac, ibuprofen, ketoprofen, mefenamic acid, and naproxen) in a real wastewater treatment plant (WWTP) using an activated sludge system and membrane bioreactors (MBRs) was investigated by using a gas chromatography/mass spectrometry (GC/MS) system for measurement of the compounds. Limited information is available for some of the tested pharmaceuticals at present. Solid retention times (SRTs) of the WWTP and the two MBRs were 7,
Direct membrane filtration (DMF) of municipal wastewater using a microfiltration membrane was investigated to capture organic matter. In contrast to the expectation that membrane fouling cannot be controlled in DMF of domestic wastewater, it was possible to stably continue membrane filtration with relatively high membrane fluxes (∼20 LMH) for >200 h by applying chemically enhanced backwash (CEB), whereas approximately 75% of the organic matter in wastewater could be recovered.
