Product Description
5.0m3/h 15ppm Bilge Water Separator
Product Introduction:
The DY-5.0 Type 15ppm Bilge Water Separator is an advanced marine pollution prevention device designed and manufactured in accordance with the IMO Resolution MEPC.107(49) — the international standard governing the discharge of oil content from machinery space bilges . This equipment ensures that the oil content in treated effluent water does not exceed 15 parts per million (ppm) , meeting the stringent requirements set by MARPOL 73/78 Annex I regulations .
The DY-5.0 model represents the largest capacity unit in the DY series, with a rated throughput of 5.0 m³/h, Beyond marine applications, this separator is also adaptable for use in industrial and petroleum sectors.
Working Principle:
The DY-5.0 Bilge Water Separator employs a multi-stage separation process to effectively treat various fluids commonly found in bilge water, including fuel oil, high-density residual oil, and emulsified mixtures combined with black ferric oxide and surfactants .
The typical separation process involves:
*Primary Gravity Separation — Utilizing the specific gravity difference between oil and water, free-floating oil is separated and rises to the surface .
*Coalescing Stage — Small oil particles are coalesced into larger droplets through specialized coalescer elements, then separated and floated to the surface .
*Polishing/Filtration Stage — The treated bilge water passes through final filtration media to ensure the effluent meets the ≤15 ppm discharge standard .
*15ppm Bilge Alarm Monitoring — The integrated XOC-01 oil content meter continuously monitors the effluent. If the 15 ppm threshold is exceeded, the alarm activates and triggers an automatic stop of overboard discharge .

Product Advantages:
The DY series 15ppm Bilge Water Separator is designed not merely to pursue the highest discharge standards, but also with thorough consideration of the practical needs of shipowners and shipyards. This design philosophy has shaped the distinctive advantages of DY products.
1. High separation precision and treatment efficiency – discharge water oil content consistently <15ppm.
2. Versatile in treating all oily pollutants from machinery space bilges, including all types of oils that may be carried on board and their mixtures in emulsion form.
3. Highly automated and user-friendly – equipped with automatic oil discharge control, automatic temperature control, and comprehensive safety protection measures; no repeated backwashing required; service life >1 year.
4. Integrated 15ppm bilge alarm device – automatically displays the oil content of the discharge water; automatically triggers alarm and recirculates back to bilge when discharge exceeds the limit, with automatic event recording.
5. Comprehensive alarm data logging – the alarm device records the date, time, alarm status, and the operating status of the bilge water separator during each alarm event; the recording unit stores data for at least 18 months, and can display and print the official inspection reports required by authorities.
6. Compact size and light weight – easy and convenient installation and maintenance.
7. Complete accessories and spare parts – backed by high-quality and efficient after-sales service.
