Since 1998 for protection of marine pollution, all ships must have oil filtering equipment and 15ppm bilge alarms which satisfy Requirements of MARPOL 73/78. Oily-water separator used in machinery area of ships usually consists of two parts; one is filtering equipment and the other is oil content meter(OCM). This study presents optical characteristics of bilge were acquired form oil content sensing module. The oil content sensing module consists of IR-LED light source, photo-diode light receivers, and a glass tube for bilge water sample. The experiment with the bilge water demonstrates various valuable optical properties. These optical properties suggest notes and guides to make the low-cost, easy operation and good performance commercial type OCM that satisfy the requirements of MARPOL 73/78.

According to the MARPOL 73/78 of Convention, all ships should have oil filtering equipment and 15 ppm bilge which satisfy Requirements of MARPOL 73/78. This study is concerned with designing and manufacturing a prototype Oil content Meter(OCM) used in machinery area of ship. The prototype OCM is composed of two parts which are oil content sensing module and data processing unit. The oil content sensing module consists of infra-red light source, photo-diode light receivers, and a glass tube for bilge water sample. The data processing unit has a micro-processor as hard core and peripheral devices. The experimental results of prototype OCM and analysis of collected data reveal linear property between transmitted light and scattered light as long as the bilge water has low level content of oil. And this linear property leads to a oil content detecting method which is programmed and loaded into the data processing unit. The performance of the prototype OCM is compared with that of the commercial OCM in the market.

Flow visualization and PIV measurements were conducted to investigate the flow characteristics of multi-channel with inclination angle. The water flow seeded with tiny vegetable powder as tracers revealed details of flow field. The PIV measurement to acquire multi-point velocity data simulatneously was carried out at three space of plates for 5, 10, and 15mm with variation of inlet flow rates of $0.25m^3/h$ and <$0.5m^3/h.$ Experiment results show that space of plates acts a significant role in separating process.

물 재이용을 위한 오일 폐수 처리 기술은 일반적으로 물과 오일을 분리하고자 하는 유수분리장치를 이용하는데, 최근 다양한 표면 개질 방법을 이용하여 기능성이 향상된 유수분리막을 기반으로 유수분리장치를 구현하고자 하는 연구개발이 지속적으로 이어지고 있다. 분리막 소재 기술은 분리 선택성 및 내구성 등 성능뿐만 아니라 경제성 및 가공성등 상용화를 위한 적용성이 검토되어야 하며, 소재의 최적 성능을 최대한 발휘될 수 있도록 효과적인 장치가 구비되어야 한다. 본 논문에서는 분리막 소재의 상용 수준의 대면적 가공성 및 효과적인 유수분리 장치에 대해서 고찰하고자 한다.
