Research Topic

Effect of membrane filtration on the infection risk of premise plumbing pathogens in decentralized water systems

Research outline

The decentralized water system, which is a small-scale water distribution system, is often the only feasible option for some rural areas, but the health of users of the decentralized system need to be properly protected from waterborne infectious pathogens. In this research, the infection risks of two premise plumbing pathogens, Legionella sp and Non-tuberculouse Mycobacterium, in a decentralized water system are calculated using Quantitative Microbial Risk Assessment (QMRA) framework. The introduction effect of membrane filtration that potentially can remove the pathogens is also studied, which will contribute to the better management of infection risks.
