Product concept and installation requirements of bilge water separator

"15 ppm bilge water separator" is a separator, a filter, a coalescer filter or any combination of other devices, or it can be a single device designed with the effluent oil content not exceeding 15 ppm.

The automatic shut-off device should be a valve device installed at the effluent outlet line of the 15 ppm bilge separator. When the oil content of the effluent exceeds 15 ppm, the mixed effluent discharged outboard will be automatically led back to the ship Bilge or sewage tank. For the sake of future inspection on the ship, a sampling point should be set at the vertical part of the drain pipe at the outlet of the 15 ppm bilge water separator as far as practicable. Recirculation equipment should be installed behind and near the outboard exit of the shut-off device so that the 15 ppm bilge water separation system, including the 15 ppm bilge water alarm device and the automatic shut-off device, can be discharged at the outboard stop. Under the circumstances. The recirculation equipment should be installed to prevent any bypass of the oil-water separator under all operating conditions. The displacement of the feed Pump shall not exceed 110% of the rated capacity of the 15 ppm bilge separator. The specifications of the pump and motor shall be recorded on the type approval certificate. The 15 ppm bilge separator should be permanently fitted with a sign indicating all operating or installation restrictions deemed necessary by the manufacturer or the competent authority.

The technical conditions of the 15 ppm bilge water separator are considered suitable for use in combination with oily bilge water and ballast water from fuel oil tanks. This is because the fuel tank volume is small or medium, and it is subject to the need to avoid discharging oil content exceeding 15 ppm oily mixture. The alarm arrangement specified in Article 16 (5) of the 15 ppm Bilge Water Alarm Device is referred to as ".. 15 ppm Bilge Water Alarm Device" in this Guide and Technical Conditions.

The so-called "ppm" refers to the oil content of water in parts per million, by volume. "Ppm display" is a digital display with 15 ppm bilge alarm. Where applicable, an automatic shut-off device is a device used to automatically shut off any outboard discharge of an oily mixture when the oil content of the effluent exceeds 15 ppm.

Ships equipped with a 15 ppm bilge separator should always carry an operation and maintenance manual. The installation pattern should be arranged so that the total response time (including the response time of the 15 ppm bilge water alarm device), that is, the oil content of the effluent from the 15 ppm bilge water separator exceeds 15 ppm to prevent outboard discharge The time required for the automatic shut-off device to start is as short as possible, in any case not more than 20 s. From the 15 ppm bilge water separator to the .. 15 ppm bilge water alarm discharge line to take samples onboard the ship should be arranged with sufficient pressure and flow to provide a truly representative effluent sample. Ships equipped with a 15 ppm bilge alarm should always carry a copy of the operation.
