Marine environmental compliance
Environmental regulations protect our marine ecosystems, but they also affect marine businesses. While it’s necessary to comply, it’s equally important to minimize the onboard impact of the solutions. By combining latest technology with regulatory insight, Alfa Laval keeps you ahead of the curve as legislation tightens, offering you flexibility and economy vital to your operations. Our advanced solutions ensure your vessels meet today's marine environmental standards for emissions control and ocean protection, while future-proofing them for evolving marine regulations.

Ballast water management
Alfa Laval pioneered ballast water management and still sets the benchmark with its latest system, Alfa Laval PureBallast® 3 Ultra. Compact and easy to install, the automated inline treatment solution offers unmatched performance in challenging waters with enhanced UV technology and improved filter performance at low power consumption. It is connectivity-ready and designed for a vessel lifetime.
Alfa Laval PureBallast 3
Alfa Laval PureBallast 3 is an automated inline ballast water management system for biological disinfection of ballast water. Operating without chemicals, it combines initial filtration with UV treatment to remove organisms in accordance with stipulated limits.
Exhaust gas cleaning (SOx)
By scrubbing harmful SOx from their exhaust gas, vessels can continue to use economical high-sulphur fuel. Alfa Laval PureSOx® is the proven and trusted scrubber solution, backed up by experience and a comprehensive service offering. Available in open-loop, closed-loop and hybrid configurations, it provides reliable compliance with both sulphur limits and water discharge regulations.
Alfa Laval PureSOx
PureSOx is the SOx scrubber system at the forefront. At sea since 2009, it has the record others aspire to, with every scrubber ever sold in operation and in compliance. The long PureSOx reference list includes a broad range of vessel types and many returning customers, convinced by smooth installations, proven results and first-rate global service.
PureSOx builds on over 50 years of work with marine scrubbers, as well as Alfa Laval core technologies like centrifugal separation, which is used for reliable water cleaning in closed-loop mode. Our experienced project management and global resources ensure smooth scrubber installation projects, while connectivity with PureSOx Connect simplifies your compliance reporting and ongoing optimization.
Oily water separation
Alfa Laval PureBilge? is a fully automated and cybersecure centrifugal separation system for cleaning oily water. By effectively removing oil pollution to a level well below 15 ppm, it sets a new standard in making water safe and compliant for discharge overboard. PureBilge operates continuously and is unaffected by feed variations, oil shocks and rough weather conditions.
Alfa Laval PureBilge
PureBilge is an efficient oily water treatment system, built for continuous use in real life conditions. By means of high-speed centrifugal separation, it can reduce oil-in-water content to less than 5 ppm – even on rough seas or in the presence of difficult emulsions. This makes it more effective and cost-efficient than static coalescers, which rely on consumable filters that quickly generate waste and cost.
Since it requires no large holding tanks, PureBilge saves a great deal of space on board. In addition, it eliminates the risk of non-compliant discharge with its tamper-proof BlueBox oil content monitor. This feature is also available in a stand-alone version, BlueBox SA, for upgrading an existing oily water treatment setup.
EGR water treatment (NOx)
In Exhaust Gas Recirculation (EGR), cleaned exhaust gas is used to reduce the engine’s combustion temperature and the formation of NOx. To safeguard EGR operation and ensure discharge compliance, the process requires water treatment. Alfa Laval PureNOx? technology offers an effective solution with more time at sea than any other, built on Alfa Laval’s centrifugal separation expertise.
Alfa Laval PureNOx
Based on centrifugal separation, Alfa Laval PureNOx has long been the choice for EGR water treatment. Today it’s available in an even more streamlined solution – PureNOx LS (Low Sulphur) – that enables more cost-efficient EGR. PureNOx LS, which has a 50% smaller separator module, cleans the EGR bleed-off water before overboard discharge. With its unique ability to treat water continuously, it is the only solution on the market to support Eco EGR, a fuel-saving engine mode in which EGR is used for Tier II as well as Tier III compliance.
PureNOx LS is optimized for EGR engines that operate on low-sulphur fuel. Upon request, solutions for use with high-sulphur fuel can also be tailored using PureNOx technology.
Crankcase gas cleaning
The oil and particles in crankcase gas are a threat to the environment and human health. Alfa Laval PureVent? is a compact solution for removing them, developed in cooperation with a major engine manufacturer. Using centrifugal separation instead of filters, PureVent returns virtually oil-free air while allowing collected oil to be recirculated as lubrication.
Alfa Laval PureVent
PureVent is a centrifugal oil mist separator for cleaning oil, soot and unburned fuel from crankcase gas. It removes up to 99.9% of the oil content, which cannot be matched by traditional cyclones, air traps or filters. To further reduce environmental impact, the collected oil can be recirculated through the separator and used again in the engine lubrication system.
PureVent is available with an open design, which releases oil-free crankcase gas directly into the atmosphere. But it can also be supplied with a closed design, where the gas is recirculated to the turbocharger. The latter completely eliminates crankcase emissions, as well as the risk of turbocharger fouling.
