CompactClean - Ballast Water Management System
What is the CompactClean Ballast Water Management System?
The CompactClean Ballast Water Management System (BWMS) is a ballast water treatment solution designed to help vessels comply with international ballast water regulations. Using a combination of filtration and ultraviolet (UV) treatment technology, the system treats ballast water during operation to prevent the transfer of invasive aquatic species between marine ecosystems. Available in multiple configurations for newbuild and retrofit projects, CompactClean can be adapted to a wide range of vessel types, operational requirements, and installation conditions.
Why choose the CompactClean Ballast Water Management System?
CompactClean is designed to help vessel operators achieve ballast water compliance while simplifying day-to-day operations. Combining UV treatment technology, a single global operating mode, flexible installation options, and long-term reliability, the system supports efficient ballast water management across a wide range of vessel types and operating conditions.
One Global Operating Mode
CompactClean operates using a single global mode that supports compliance with both IMO and USCG ballast water requirements. This eliminates the need to select different treatment modes during ballast water uptake, helping reduce operational complexity and the risk of compliance issues when trading between different regions.
Certified for Challenging Water Conditions
CompactClean is certified to treat ballast water in water conditions with UV transmittance levels down to 40%. This enables reliable treatment performance across a broad range of water qualities and trading routes while maintaining regulatory compliance.
Flexible Installation Options
To accommodate different vessel designs and installation constraints, CompactClean is available as skid-mounted, low skid-mounted, and loose-component configurations. These options make the system suitable for both newbuild projects and retrofit installations where available space may be limited.
Smooth Port Operations
CompactClean is designed to support uninterrupted ballast water operations in varying water conditions. Automated system controls and intelligent treatment management help minimize operator intervention while supporting efficient ballasting and de-ballasting procedures.
Efficient and Reliable Long-Term Performance
The CompactClean UV treatment system is engineered for efficient operation and long service life. UV units manufactured in corrosion-resistant Nickel-Alu-Bronze provide excellent seawater resistance, while the optimized UV treatment process helps reduce energy consumption and support lower operational costs throughout the system lifecycle.
How does CompactClean treat ballast water?
The CompactClean Ballast Water Management System combines automatic filtration and ultraviolet (UV) treatment technology to prevent the transfer of invasive aquatic species between ecosystems. The treatment process takes place during ballast water uptake and is designed to support compliance with international ballast water regulations without the use of active substances.
Filtration during ballast water uptake
During ballast water uptake, water passes through an automatic filter designed to remove larger organisms and suspended particles before treatment. This filtration stage helps optimize the performance of the UV reactor while protecting downstream equipment.
UV Treatment Technology
Following filtration, the ballast water enters the UV treatment chamber where microorganisms are exposed to high-intensity ultraviolet light. The UV treatment prevents organisms from reproducing, reducing the risk of transferring non-native species to new marine environments.
Integrated Ballast Stripping solution
During ballast tank stripping operations, CompactClean uses the filter backflush pump as a stripping pump to evacuate residual ballast water from the tanks. This integrated approach eliminates the need for a dedicated stripping ejector while ensuring that ballast water continues to be handled through the ballast water management system. The solution helps simplify system design, reduce equipment requirements, and support compliant ballast water operations.

Frequently Asked Questions about CompactClean
What is a ballast water management system (BWMS)?
A ballast water management system treats ballast water to prevent the transfer of invasive aquatic species between marine ecosystems. BWMS solutions help vessels comply with international ballast water regulations by treating ballast water before it is discharged.
How does CompactClean treat ballast water?
CompactClean combines automatic filtration and ultraviolet (UV) treatment technology to treat ballast water during operation. The filtration stage removes larger organisms and particles, while the UV treatment inactivates microorganisms without the use of active substances or treatment chemicals.
Is CompactClean approved for IMO and USCG compliance?
Yes. CompactClean is designed to support compliance with both IMO and USCG ballast water requirements through a single global operating mode, helping simplify ballast water operations worldwide.
What is the advantage of a single global operating mode?
A single global operating mode removes the need to select different treatment modes depending on where ballast water will be discharged. This helps simplify operation and reduces the risk of having ballast water that is compliant in one region but not in another.
Which vessels can use CompactClean?
CompactClean is suitable for a wide range of vessel types, including bulk carriers, container vessels, tankers, offshore support vessels, fishing vessels, naval vessels, and retrofit projects where installation flexibility is required.
How do I choose the right CompactClean configuration?
The right CompactClean configuration depends on factors such as ballast flow rate, vessel type, available installation space, hazardous area requirements, and whether the project is a newbuild or retrofit. CompactClean is available as skid-mounted, low skid-mounted, and loose-component systems to accommodate different installation requirements.
