Alfa Laval PureBallast 3 Ultra is the latest ballast water management system built on proven PureBallast 3 technology. Offering increased performance in challenging waters and even easier installation, it can be configured for ballast water flows of 42–3000 m3 /h, as well as Ex requirements. PureBallast 3 Ultra 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.
