15 ppm OWS

medium 161 / 161 models (Inspector)

A 15 ppm OWS is the specific bilge water treatment train sized to hold outlet oil content under 15 ppm continuously, with a monitor that automatically stops discharge the moment it drifts over the limit, rather than just alarming.

What makes a 15 ppm unit different

Every oily water separator on a ship is designed to bring bilge water below a legal oil content limit before it reaches the overboard valve, but the "15 ppm" designation is specific: it names the separator built and certified to hold outlet oil content under 15 parts per million continuously, verified by an inline oil content monitor rather than by periodic sampling. Older 100 ppm bilge separators still exist on some vessels under grandfather clauses, but any newbuild or retrofit fitted after the relevant MEPC amendment must meet the 15 ppm standard with a monitor that stops discharge automatically, not just an alarm a watchkeeper could silence.

15 ppm oily water separator train — Block flow diagram of a 15 ppm oily water separator, from bilge holding tank through feed pump, gravity and coalescer stages, fine filter and continuous monitor to either overboard discharge or automatic return to the bilge tank on alarm.

Main components

Gravity/coalescing first stage

Bilge water enters a settling chamber where free oil separates by density difference and rises to a collection zone. Coalescing plates or packs increase the surface area available for small droplets to combine into larger ones that rise faster, cutting the residence time needed for a given oil removal rate.

Second stage (fine filter or coalescer)

A second unit, either a stacked coalescer, a fine mechanical filter, or in some designs a chemical/absorption cartridge, removes the emulsified and dissolved fraction the first stage cannot touch. This stage decides whether the unit can reliably hit 15 ppm on real, emulsified engine room bilge water rather than clean test water.

Oil content monitor (OCM)

An in-line monitor, usually optical, continuously measures the treated water and automatically diverts the discharge back to the bilge holding tank the instant the reading approaches 15 ppm. The monitor is a separately type-approved instrument under its own certificate, distinct from the separator's own approval.

Automatic stopping/diverting device

A three-way valve or pump-stop function, driven by the OCM, is mandatory: the system must fail safe to recirculation, not to sea.

Selection and sizing

Capacity is rated in cubic metres per hour and chosen against the bilge pumping rate of the engine room bilge system, not vessel size alone. Key figures against the specification: rated throughput, maximum inlet oil concentration the unit is designed for (raw bilge runs far dirtier than the 15 ppm limit), and the type approval certificate number referencing the applicable IMO resolution. Internals in way of the bilge pump discharge are usually stainless steel or coated carbon steel, since bilge water carries detergents, fuel residue, and sometimes seawater.

Regulations and class

MARPOL Annex I, Regulation 14, sets the 15 ppm discharge limit and requires approved oil filtering (separating) equipment with alarm.
IMO Resolution MEPC.107(49) is the current test and approval standard for 15 ppm separators fitted from 2005 onward, superseding MEPC.60(33).
The oil content meter is approved separately, and class checks its calibration and alarm/stop function during survey.
Every discharge and any equipment failure must be logged in the Oil Record Book (Part I), which flag administrations and port state control check closely.

Typical faults

Fault	Consequence
Coalescer media fouled with sludge or detergent residue	Rising differential pressure, falling separation efficiency, eventual automatic stop on every cycle
OCM optical cell dirty or miscalibrated	False stops (nuisance recirculation) or, worse, false-clean readings that mask an actual overboard discharge violation
Emulsified bilge water from heavy detergent use during tank cleaning	Unit cannot meet 15 ppm regardless of condition; this is an operational cause, not equipment failure
Three-way valve stuck or bypassed manually	Untreated water can reach the overboard discharge, the classic MARPOL violation scenario investigated by port state control

What to look for in a supplier

Current type approval certificate referencing MEPC.107(49), matched to the flag state the vessel trades under.
Coalescer element and OCM spares reachable through a network at the ports the vessel actually calls, not just the maker's home port.
Documented performance on real bilge water, not only on the standard test oil/water mixture used for certification.
OCM compatibility with any bilge water monitoring system already fitted, to avoid a costly retrofit of the electronic interface.

Never accept an OCM reading at face value if the sight glass shows visible sheen; port state control inspectors know the bypass tricks, and a falsified oil record book is a career-ending finding, not a minor deficiency.

Strengths

High processing capacity – up to 5 000 L/h (PureBilge 5015) while staying below the 15 ppm MARPOL limit
Integrated EPC 60/70 controller with cyber‑security features and full data logging for audit trails
Compact footprint and modular design suitable for retrofits on existing vessels
Coalescent pre‑filter plus pre‑heater improves oil droplet capture efficiency, often achieving <5 ppm discharge
Well‑documented maintenance schedule (optical cell calibration, membrane replacement) supporting predictable OPEX

Weaknesses

Membrane elements require replacement every 12–18 months, adding recurring cost and downtime
Optical oil‑content sensor is sensitive to fouling; frequent calibration/verification needed to stay compliant
Pre‑heater draws significant electrical power (typically 5–8 kW) which may be a concern on low‑power vessels
System is optimized for bilge water only – not suitable for high‑viscosity sludges or other oily waste streams
Initial capital outlay is higher than basic centrifugal OWS units

Typical Vessels: Crude oil tankerProduct tankerBulk carrierContainer shipOffshore supply vesselCruise liner (large engine rooms)

Certifications: DNV GL Type ApprovalABS Approved EquipmentIMO MARPOL Annex I compliance

Decision Guide: Choose if the vessel requires reliable 15 ppm oil‑in‑water compliance, has sufficient electrical power for a pre‑heater, and can accommodate the scheduled membrane replacement. Avoid on ships with very limited space, low power availability, or where only occasional bilge discharge is expected and a simpler centrifugal separator would suffice.

Use Cases: Installed in engine rooms to continuously treat bilge water from machinery spaces, fuel oil transfers, and deck wash‑down before discharge overboard. The system feeds directly into the ship's Oil Record Book monitoring and can be integrated with ballast water management systems for combined compliance reporting.

Medium

Bilge Water

Type

Coalescer OWS

Common Failures & Inspection Points

Separation-stage, bowl, coalescer or filter fouling reduces treatment efficiency and causes poor outlet quality or alarms
Monitor, sensor or sampling-line contamination causes unstable readings or unnecessary recirculation and trips
Seal, gasket or bowl-sealing faults cause leakage or loss of correct separation conditions
Feed-pump, drive or bearing faults cause unstable flow, vibration, abnormal noise or shutdown
Incorrect temperature, flow, interface or chemical condition causes poor separation despite apparently normal machinery

Service: Inspect the separation element or bowl, filters, pumps, seals, monitoring, sample lines and sludge or discharge arrangements. Review outlet quality and operating trends and verify that approved discharge paths cannot be bypassed where statutory controls apply. Clean and test monitors according to the approved procedure. Refer to the manufacturer documentation for the exact figure for flow, temperature, pressure and calibration criteria.

Spare Parts: Carry filters or coalescers, bowl or seal kits as applicable, pump seals, monitor service parts, solenoids, sample-line fittings, gaskets and selected sensors.

Strengths

Simple, rugged construction – easy to install and operate
Low maintenance schedule (coalescer change annually, OCM calibrated monthly)
Compact footprint suitable for retrofits on medium‑size vessels
Consistently achieves 15 ppm oil discharge limit when maintained
Cost‑effective compared with more complex electronic OWS units

Weaknesses

Coalescer element can clog if not replaced on schedule, reducing efficiency
Optical Counter‑Measure (OCM) sensor drift requires regular calibration
Pump seal leakage reported in field service bulletins
Control panel electronics may develop faults under harsh vibration
Limited maximum flow capacity for very high‑throughput vessels

Typical Vessels: Bulk CarrierContainer ShipGeneral Cargo VesselOffshore Supply VesselFishing Vessel

Decision Guide: Choose if you need a proven, low‑cost OWS that meets the 15 ppm standard on vessels with moderate bilge flow and can accommodate routine maintenance. Avoid if your vessel requires high‑capacity treatment, advanced remote monitoring, or you cannot guarantee regular coalescer replacement and sensor calibration.

Use Cases: Bilge-water treatment, fuel and lubricating-oil purification and other shipboard liquid-separation duties.

Common Failures & Inspection Points

Coalescer, filter, or separation-stage fouling from sludge and solids raises pressure drop, reduces throughput, or causes poor separation
Oil-content monitor contamination, calibration drift, or sampling-line blockage causes unstable readings, alarms, or diversion despite apparently clean water
Valve, solenoid, or automatic stopping-device faults from sticking, air failure, or electrical problems prevent correct recirculation or overboard control
Feed-pump wear, air ingress, or suction blockage causes low flow, loss of prime, cavitation, or inability to process the bilge tank
Excessive emulsified oil, detergents, chemicals, or unsuitable bilge composition overwhelms separation performance and results in persistently high oil-content readings

Service: Inspect separation stages, filters or coalescers, sludge drains, pump condition, sample lines, oil-content monitor cleanliness and calibration status, automatic stopping/diverting function, seals, valves, and record-book consistency. Testing and discharge operations must follow MARPOL, vessel procedures, and the approved equipment documentation.

Spare Parts: Carry approved filter or coalescer elements, seals and gaskets, monitor service consumables, sample-line items, pump seals, and critical valve or solenoid parts recommended for the installed model.

Use Cases: Used on merchant ships, offshore vessels, passenger ships, fishing vessels, and other powered vessels with machinery-space bilge water requiring approved treatment before any permitted discharge.

Common Failures & Inspection Points

Separation-element fouling caused by sludge, detergents or excessive oil loading, resulting in poor separation and repeated high-oil-content alarms
Oil-content monitor contamination or calibration drift caused by dirty sample lines or sensor fouling, resulting in unstable or implausible readings
Automatic recirculation or discharge-valve failure caused by actuator, solenoid or control faults, resulting in inability to route off-specification water correctly
Feed-pump or suction problems caused by blockage, air ingress or pump wear, resulting in unstable flow and poor separator performance
Internal leakage or bypassing caused by damaged seals, incorrect assembly or unauthorized piping changes, resulting in non-compliant operation or abnormal sample results

Service: Inspect separator chambers, coalescing or filter elements, sample lines, oil-content monitor, automatic stopping or recirculation devices and associated valves. Keep bilge feed as free as practicable from detergents and emulsifying chemicals that can impair separation. Flush and clean sample lines and sensors according to the approved manual and verify alarms and automatic diversion functions after maintenance. Check the piping arrangement against approved drawings and ensure no bypass route compromises the system. Maintain required operating and calibration records. Refer to the manufacturer documentation for the exact figure for test methods, element replacement criteria and operating limits.

Spare Parts: Keep approved separation or filter elements, seals, gaskets, sample tubing, monitor service items, valve-actuator consumables and feed-pump spares recommended for the installed system. Any oil-content monitor replacement or calibration component must match approved equipment. Use only parts accepted for the certified configuration.

Use Cases: Treatment of machinery-space oily bilge water on merchant ships and offshore units before recirculation, shore disposal or permitted monitored discharge.

Medium

Bilge Water

Type

Electrocoagulation OWS

Common Failures & Inspection Points

Separation-stage, bowl, coalescer or filter fouling reduces treatment efficiency and causes poor outlet quality or alarms
Monitor, sensor or sampling-line contamination causes unstable readings or unnecessary recirculation and trips
Seal, gasket or bowl-sealing faults cause leakage or loss of correct separation conditions
Feed-pump, drive or bearing faults cause unstable flow, vibration, abnormal noise or shutdown
Incorrect temperature, flow, interface or chemical condition causes poor separation despite apparently normal machinery

Spare Parts: Carry filters or coalescers, bowl or seal kits as applicable, pump seals, monitor service parts, solenoids, sample-line fittings, gaskets and selected sensors.

Strengths

No disposable filter media – lower recurring cost
High removal efficiency for emulsified oils common in bilge water
Predictable electrode wear schedule simplifies maintenance planning
Compact unit suitable for retro‑fit on existing vessels

Weaknesses

Electrode degradation requires periodic replacement, causing planned downtime
Sensitive to power supply quality; failures can halt treatment
Sludge generated by coagulation must be removed and disposed of regularly
pH control system adds complexity and may need adjustment in variable bilge conditions

Typical Vessels: TankerBulk CarrierContainer ShipOffshore Supply VesselFishing Vessel

Decision Guide: Choose if the vessel operates with high‑emulsion bilge water, wants to eliminate consumable filter costs, and can accommodate scheduled electrode replacement and sludge handling. Avoid if power quality is poor, maintenance windows are extremely limited, or the crew lacks experience with pH control and sludge disposal.

Use Cases: Bilge-water treatment, fuel and lubricating-oil purification and other shipboard liquid-separation duties.

Spare Parts: Carry filters or coalescers, bowl or seal kits as applicable, pump seals, monitor service parts, solenoids, sample-line fittings, gaskets and selected sensors.

Strengths

Consistently achieves 15 ppm compliance under MARPOL Annex I requirements
Multi‑stage filtration reduces oil carry‑over and improves effluent quality
Differential pressure monitoring enables predictive filter element replacement
Integrated OCM sensor with recommended annual calibration ensures reliable detection
Compact modular design facilitates retrofits on existing vessels

Weaknesses

Filter elements can become blocked if differential pressure is not regularly checked, leading to alarm trips
Solenoid valve may stick, requiring periodic manual inspection and maintenance
OCM sensor contamination is possible in high‑oil load conditions
Maintenance intervals may be shorter on vessels with heavy bilge water generation
Lack of publicly documented certifications could limit acceptance in jurisdictions that require specific approvals

Common Failures & Inspection Points

Separation-stage, bowl, coalescer or filter fouling reduces treatment efficiency and causes poor outlet quality or alarms
Monitor, sensor or sampling-line contamination causes unstable readings or unnecessary recirculation and trips
Seal, gasket or bowl-sealing faults cause leakage or loss of correct separation conditions
Feed-pump, drive or bearing faults cause unstable flow, vibration, abnormal noise or shutdown
Incorrect temperature, flow, interface or chemical condition causes poor separation despite apparently normal machinery

Spare Parts: Carry filters or coalescers, bowl or seal kits as applicable, pump seals, monitor service parts, solenoids, sample-line fittings, gaskets and selected sensors.

Strengths

Integrated two‑stage treatment (coalescer + carbon) meets the strict 15 ppm MARPOL limit
Modular cartridge design allows quick replacement of coalescer and carbon elements
Proven reliability on a wide range of commercial vessels with an extensive Veolia service network
Compact footprint suitable for limited engine‑room space

Weaknesses

Activated‑carbon element requires periodic replacement, adding consumable cost
Solenoid valve and OCM (oil content monitor) can drift and need regular calibration checks
Maximum flow capacity may be insufficient for very high‑discharge vessels
Carbon exhaustion can lead to occasional oil breakthrough if not monitored

Typical Vessels: Product TankerChemical TankerBulk CarrierContainer ShipOffshore Supply VesselGeneral Cargo Vessel

Certifications: IMO D‑2 (Marine Pollution Prevention)

Decision Guide: Choose if you need a reliable, compact OWS that delivers ≤15 ppm oil with built‑in polishing and have access to Veolia/Damen after‑sales support. Avoid if the vessel has very high bilge‑water flow rates or you prefer a carbon‑free system to reduce consumable maintenance.

Use Cases: Bilge-water treatment, fuel and lubricating-oil purification and other shipboard liquid-separation duties.
