Abstract

For application in small-scale water facilities,important boundary conditions for decentralized systemsinclude low costs, low maintenance, sustainability. Althoughsome low-cost systems are available, their application is limitedby time-consuming daily operation and maintenance. On theother hand, membrane systems are attractive since they providean absolute barrier for organic compounds and removeturbidity. Accordingly, we developed the membrane basedwater treatment package system for small- scale water supplyfacilities, and its applicability was examined. The decentralizedwater treatment package system consisted of DMF, UF, and UVunit. Each unit combination was made to ensure the processingcapacity of 100 m3 per day. In addition, a decentralized watertreatment package system was manufactured using 10ftcontainers compliant with IOS standards due to limitation ofgrounds at small-scale water supply facility. In case ofsmall-town in Korea, underground water is mainly used as rawwater. Therefore, this package system was installed andoperated at the upper region of the ANDONG in Korea. Fouritems including temperature, pH, conductivity, turbidity weremonitored to analyze underground water quality. In addition,the water treated by the system was analyzed to identifywhether it satisfies drinking water quality standards. After theexamination of applicability, on the basis of water usage percapita per day, the system was able to produce enough water for300 people. During the operation, the produced water satisfiedall 48 items of drinking water quality standards. Thus it issurmised that the system could be used for small-scale watersupply facilities.
