PureBallast 3 treats ballast water without chemicals, combining high-performance filtration with enhanced UV treatment. In the UV reactor(s), specially designed synthetic quartz lamp sleeves transmit an extended wavelength spectrum that provides more UV light. Together with the internal reactor design, this ensures optimal UV dosage with very low energy consumption. An expanded range of reactor sizes further reduces power needs in specific configurations.

PureBallast 3 Ultra
PureBallast 3 Ultra offers unmatched biological disinfection performance in any type of water: fresh, brackish or marine. An expanded range of UV reactor sizes ensures a close match between PureBallast 3 Ultra and the ballast pump capacity. For certain flows, this reduces power needs by up to 19% over previous systems. System layout is simplified by the smaller design of the upgraded filter, as well by the integration of the Cleaning-In-Place (CIP) unit and pressure monitoring device into the UV reactor module.

How it works
Clear benefits for UV performance with Cleaning-in-Place
UV ballast water management systems are chemical-free and pose no risk to the ballast water tanks. However, they depend on regular cleaning to remove seawater scaling and fouling from the UV lamp sleeves and sensors. In PureBallast 3, cleaning is done through gentle, automated Cleaning-In-Place (CIP).

Compliance depends on crew knowledge
Training is a prerequisite for optimizing the performance of your equipment and safeguarding your investment. In the case of your ballast water treatment system, it also safeguards your compliance. Having the right ballast water treatment system is only one part of securing compliance. The crew must also be able to use it – safely, correctly and efficiently.
