Aquarius UV ballast water management system

AQUARIUS UV ballast water management system is one of the most robust solutions for ballast water treatment. It uses a 2-stage process involving filtration and ultra-violet (UV) irradiation. It can be used across the full range of ship operating and environmental conditions.

The system uses no active substances or chemicals, is easy to integrate, operate and maintain. The Aquarius UV is type approved to the latest IMO and USCG regulations. It is available in for installation in both engine room and hazardous areas on tankers as an EX version.

Wärtsilä Water & Waste works in close cooperation with its customers. Our BWMS partnership program covers all stages, from fleet evaluation to lifecycle support. Wärtsilä’s tailored turnkey solutions help minimize your environmental footprint, improve operational efficiency and comply to IMO and USCG standards.

    KEY BENEFITS

    Benefits of Aquarius® UV treatment:

    • Medium pressure crossflow UV reactor using our dedicated global UV partner who also manufacture the lamps, this gives us an extremely stable supply chain
    • The reactor body is manufactured from high grade materials and designed to eliminate corrosion
    • The high quality quartz lamp sleeves have a self-cleaning mechanical wiper, this wiper operates both during operation and between operations to maintain the highest performance possible from the lamps, no cleaning chemicals or rigs are required
    • The system does not rely on sleeves cleaning themselves from the water flow, this is not a sustainable approach
    • Competitive lamp life durations
    • High quality quartz sleeves and instrumentation ensure compliant treatment

    Aquarius® UV in operation

    System operation is incredibly straight forward. Simply select an operation mode and start the ballast pump when requested. The warm-up of the Aquarius® UV is fully automatic. No sea-to-sea operation is required during this phase. From this point the system will look after itself until shutdown. Crew interaction is limited to annual maintenance needs and occasional watchkeeping of the unit.

    UV ballast water treatment

    The Aquarius® UV BWMS uses a medium pressure UV reactor to provide the second stage of treatment during ballast uptake. It  also treats the ballast water on discharge, prior to overboard discharge. This reactor works intelligently to always provide the dose needed to meet the type approved parameters for treatment of the ballast water. This dose control is a critical part of the treatment process and critical to treatment success.
