Automatic Bilge Water Separator

Automatic Bilge Water Separator

The YSZ-0.25 Automatic Bilge Water Separator is a precision-engineered, space-optimized oily water separation system specifically designed for small vessels and tight engine room installations where every square meter counts. This complete treatment unit processes oily bilge water to achieve ≤15ppm purity levels, ensuring full compliance with IMO MEPC.107(49) international standards for overboard discharge.

Ideal for small commercial vessels, workboats, fishing boats, and specialized marine applications, the YSZ-0.25 delivers the same reliable performance as larger systems but in a compact footprint that fits easily into confined machinery spaces. Despite its small size, it incorporates the same advanced separation technology found in systems for ocean-going vessels.

Complete IMO-Compliant System Package

To comply fully with IMO MEPC.107(49) requirements, ocean-going ships must be equipped with three essential components:

1. 15ppm Bilge Separator – The primary treatment unit

2. 15ppm Bilge Alarm – Continuous effluent monitoring

3. Automatic Stopping Device – Prevents non-compliant discharge

The YSZ-0.25 integrates all these elements into a complete, ready-to-install system. The main components feature internationally renowned brands for guaranteed reliability and performance:

• Electrical Control Box Components: Schneider (global leader in electrical management)

• 15ppm Bilge Alarm: DECKMA Hamburg (German precision oil content monitoring)

• Screw Pump: Mono Pump (recognized worldwide for durability and reliability)

Engineered for Tight Spaces, Built for Performance

With its compact dimensions and efficient layout, the YSZ-0.25 fits easily into small engine rooms where space is at a premium. Yet it delivers the same robust performance as larger units, processing up to 2.50 m³ of bilge water per hour while maintaining effluent quality well below the 15ppm limit.

Frequently Asked Questions (FAQs)

Q1: What is the significance of IMO MEPC.107(49) compliance?
A: IMO MEPC.107(49) is the International Maritime Organization resolution that sets the performance standards and test specifications for oily-water separating equipment and oil content meters. This certification is mandatory for all vessels subject to MARPOL Annex I. Type approval to MEPC.107(49) guarantees that the bilge water separator has been independently tested and proven to consistently achieve the required ≤15ppm effluent quality under specified conditions, ensuring compliance with international regulations and preventing port state control detentions.

Q2: Why are three separate components (separator, alarm, stopping device) required?
A: IMO regulations require a complete system with redundant safety features:

1. 15ppm Separator: Performs the actual oil-water separation.

2. 15ppm Alarm: Continuously monitors effluent quality. If the separator malfunctions and oil content approaches or exceeds 15ppm, the alarm activates.

3. Automatic Stopping Device: When the alarm triggers, this device automatically diverts non-compliant flow back to the bilge tank and/or stops overboard discharge, ensuring that no polluted water ever enters the marine environment.
   This three-part system provides multiple layers of protection against accidental pollution.

Q3: Why are premium brands like Schneider, DECKMA, and Mono specified for this system?
A: The YSZ-0.25 incorporates globally recognized brands for critical components because:

• Schneider Electric: World leader in electrical control and automation. Their components ensure reliable operation, precise control, and global availability of spares.

• DECKMA Hamburg: German manufacturer specializing in marine oil content monitors. Their 15ppm alarms are trusted worldwide for accuracy and reliability under demanding conditions.

• Mono Pump: Renowned for durable, low-maintenance screw pumps that handle oily bilge water without creating emulsions that could reduce separation efficiency.
  Using these premium components ensures long-term reliability and simplified maintenance.

Q4: What is the difference between dry weight and wet weight?
A:

• Dry Weight (1500 kg): The weight of the separator system itself, empty of fluids. Used for shipping, lifting, and installation planning.

• Wet Weight (2800 kg): The operational weight when the system is filled with water and fluids. Used for structural support calculations for the deck or foundation where the unit will be mounted.
  The 1300 kg difference represents the water and fluids contained within the system during normal operation—this must be considered when designing the supporting structure.

Q5: What does “suction head not more than 6m-H₂O” mean for installation?
A: Suction head refers to the vertical distance between the water level in the bilge tank and the pump inlet. A maximum suction head of 6 meters water column means:

• The pump can lift water from a bilge tank located up to 6 meters below the separator.

• Installation must ensure the vertical lift does not exceed this value.

• Exceeding this limit may cause cavitation, reduced flow, or pump failure.
  This parameter is critical for proper system layout in vessels with deep bilge tanks.

Q6: What routine maintenance does the YSZ-0.25 require?
A: Regular maintenance ensures optimal performance:

• Daily: Visual inspection for leaks, check pressure gauges.

• Weekly: Verify alarm operation, inspect pump for unusual noise.

• Monthly: Clean strainers, check oil levels in pump, inspect electrical connections.

• Quarterly: Test safety devices, verify calibration of 15ppm alarm (per manufacturer’s instructions).

• Annually: Professional service of pump, replace seals if needed, internal inspection of separator, pressure vessel inspection if required.

• As Needed: Replace filter elements, clean separation plates, service DECKMA monitor per manual.
