| Abstract |
| In this research, direct coupled pressurized WTP(Water Treatment Plant) of multi stories structure(1,000 ㎥/day) was constructed and operated. WTP consisted of membrane filtration(UF), ozone, granular activated carbon(GAC) and UV disinfection. All equipment was grouped as a unit process to measure electricity consumption. As a results of electricity consumption analysis, intake and supply pump consume great part of electricity(34.51%), total electricity consumption of plant operation except for intake and supply pump was 0.36～0.41 kWh/㎥. Electricity consumption for UF, O3, GAC, UV and operating facility(computer server, monitoring and control system) were approximately 0.2, 0.144, 0.013 and 0.029, 0.066 kWh/㎥, respectively. All differential pressure result from direct coupled plant configuration loaded to UF feed pump, therefore UF feed pump is a most important equipment in aspect of energy saving. |
