요시히코 마츠이 교수의 연구실은 수질 정화 및 환경 공학 분야에서 주로 활동하며, 특히 응집제를 이용한 미세입자 및 바이러스 제거, 활성탄을 활용한 유기오염물질 제거 메커니즘, 그리고 고체-액체-가스 상호작용을 고려한 연료 재형성 기술에 중점을 두고 있습니다. 특히 알루미늄 기반 응집제의 응집 동역학과 자연유기물(NOM)이 활성탄 흡착에 미치는 영향에 대한 깊이 있는 연구를 수행하고 있습니다. 최근에는 고온·고압이 아닌 조건에서의 플라즈마를 이용한 연료 재형성 기술에도 관심을 기울이고 있습니다.

Inorganic aluminum salts, such as aluminum sulfate, are coagulants that cause small particles, such as bacteria and viruses as well as inorganic particles, to destabilize and combine into larger aggregates. In this investigation, batch coagulation treatments of water samples spiked with Qbeta, MS2, T4, and P1 viruses were conducted with four different aluminum coagulants. The total infectious virus concentration in the suspension of floc particles that eventually formed by dosing with coagulant

The adsorptive removal of periodic spikes of the trace synthetic organic chemicals (SOCs) simazine and asulam from water containing natural organic matter (NOM) was studied in pilot-scale granular activated carbon (GAC) adsorbers over a period of nearly 3 years. The SOC removal percentage obtained at any preloading time and bed depth was independent of the liquid-phase SOC concentration, and equations derived from the ideal adsorbed solution theory and a pore surface diffusion model validated th
The principal objective of this study was to elucidate mechanisms by which NOM affects the adsorption of a nonpolar (simazine) and a polar (asulam) herbicide on activated carbon. Experiments were carried out in microcolumns that were continuously fed solutions containing NOM with different molecular weight (MW) distributions and intermittently solutions containing the same NOM plus simazine or asulam. The MW distributions of a groundwater NOM were altered by coagulation and ultrafiltration, whic
PACl more effectively coagulates fine particles than alum. The coagulation kinetics of polyaluminum chloride (PACl) and alum applied to kaolin clay suspensions were compared in batch experiments. Increasing aluminum (Al) dosages reduced the time required for particles destabilization and increased the rate at which the number of primary particles decreased. PACl worked faster than alum. Photometric dispersion analysis showed that increasing Al dosages decreased the time required for floc to form
