- U.S. Coast Guard and IMO type approved
- Full flow even down to 42% UV transmittance
- Energy efficient performance
- Simple, chemical-free operation with full automation
- Flexible solutions for newbuilds, replacement or retrofit for any vessel type
Type approved by IMO and the U.S. Coast Guard (USCG), PureBallast 3 Non-Ex and Ex systems are designed for ballast water treatment in all types of water – fresh, brackish and marine. They can be configured for flows of 32–3000 m3 /h, with multiple systems used for larger capacities. Due to their enhanced UV technology and power ramp-up capabilities, these systems provide unmatched biological disinfection performance in low-clarity waters. When operating in IMO-regulated waters, full-flow treatment is possible where the UV transmittance is as low as 42%.
UV or EC? Why your choice of ballast water management technology matters
Decisions in ballast water management shouldn’t be made by default, especially when it comes to your choice of technology: UV or electro chlorination (EC). By raising the right questions, you can lower a lot – from your costs and risks to your operating limitations. Find out why UV treatment with Alfa Laval PureBallast 3 is the smartest choice for ballast water management, even on vessels where EC is today’s norm.
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.
Ballast water regulation
As you look into ballast water treatment solutions, the word “compliance” is one you’ll come across in one form or another. It’s a little word, but it’s a bigger concept – and it concerns some major obligations for ballast water treatment systems and you. Service and maintain your system according to suppliers specification - Crew training - Calibration - Water sampling Compliance is never a one-time thing. You have to keep at it over time.
IMO type approval
PureBallast 3 was specifically developed for the demands of the marine environment, with the needs of marine customers firmly in mind. Our work in ballast water treatment is part of a larger effort. Alfa Laval is committed to meeting legislative demands with workable, sustainable solutions that go unnoticed on board. Alfa Laval PureBallast 3 is certified for use in all water salinities: fresh, brackish and marine
USCG type approval
The USCG type approval for PureBallast 3, which allows the discharge of ballast in United States waters, was issued in December 2016. Today’s PureBallast 3 is certified for use in all water salinities: fresh, brackish and marine. The type approval testing was performed using the CMFDA/FDA (staining) method and the same hardware, power consumption and flow as the IMO-approved version of the system.
Type approval for early generations
Most systems of the previous generation, PureBallast 2, can also be upgraded for USCG type approval. In April 2020, USCG tests were completed using a PureBallast 2 system with a Boll & Kirsch filter and minor modifications. The solution was type approved in November 2020 and can operate in both seawater and brackish water.

Clear benefits for UV performance with Cleaning-in-Place
UV ballast water treatment 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. n PureBallast 3, cleaning is done through gentle, automated Cleaning-In-Place (CIP).
