Abstract

Small water supply systems provide safe drinking water to small communities. This study developed, built, and tested a self-sustained small water supply system with an annual capacity of 1000 m³ , using 20 surface-modified PTFE membranes for a total filtration area of 1.42 m². The system includes a settling tank, membrane module, filtrate tank, chemical tank, pumps, pipes, and a control panel. It was installed and operated in a remote site of northern Taiwan for 242 days, even during power outages and typhoons. Operational and maintenance costs for small water supply systems can be high due to extensive chemical use and workforce demands, while ensuring the reliability of these systems is also a public health and safety challenge. Long-term tests showed the present system produced quality drinking water without coagulants or disinfectants, significantly reducing chemical costs. The system was self-sustained with minimal maintenance, lowering workforce costs. It achieved a water production cost of 0.18 USD/m³ , much lower than the tariffs in most countries.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
