Advantages of PureBallast 3

A unique combination of capabilities sets PureBallast 3 apart from any other ballast water treatment system.

Superior treatment performance

PureBallast 3 offers unmatched biological disinfection performance in all water salinities: fresh, brackish or marine. This includes water in liquid form at frigid temperatures, as well as the low-clarity conditions in challenging harbours and waterways. Even in low-clarity waters with UV transmittance as low as 42%, the system can perform at full flow, which lets you ballast and deballast efficiently.

High energy efficiency

PureBallast 3 runs at just 50% of its potential operating power in most situations when operating in IMO-regulated waters. It can then be ramped up to full power for the most difficult operating scenarios. This energy-efficient performance is maintained through automatic Cleaning-In-Place (CIP), which removes UV-impairing build-up without crew effort or the risk of scratching the lamp sleeves.

 

Simple, chemical-free operation

PureBallast 3 is fully enclosed, fully automated and thoroughly integrated with the ballast water system. In other words, its operation requires nothing from the crew.

Likewise, PureBallast 3 needs no salt or chemicals, even when operating in fresh water. No dosing is involved, and there are no tanks or ventilation systems needed to manage consumables or residuals.

Space-saving inline construction

PureBallast 3 is an inline system in which the major components (filter and reactor) are incorporated into the ballast water piping. The reactor, which is made of superaustenetic stainless steel for a lifetime of at least 20 years, has a diameter only marginally larger than that of the piping itself. This creates a highly flexible system with a small footprint, which is especially important for retrofits.

 

Vessel-specific solutions

The PureBallast 3 offering includes solutions for the challenges of particular vessel types. These include Ex configurations, which are simplified by the ability to place the power supply outside the hazardous zone. Other examples include the PureBallast 3 bulker-fit configuration, which is adapted for bulkers’ differentiated ballasting/deballasting flows, and deckhouse solutions for tankers, with or without an integrated booster pump unit.

IMO and USCG type approvals

Alfa Laval’s PureBallast 3 offering has all the certifications needed to ensure security and flexibility – today and tomorrow.

Compliance for all demands

PureBallast 3 gives your vessel freedom of movement with the fewest operating limitations. PureBallast 3 systems have IMO and USCG type approvals and are certified for use in fresh, brackish and marine waters. Three-water certification is important beyond rivers or the Baltic and Great Lakes, as many ports considered brackish are actually farther from the marine end of the transition zone and closer to fresh water.

PureBallast 3 has IMO revised G8 type approval, which means systems purchased today can be installed after the stricter IMO guidelines take effect on 28 October 2020. Alfa Laval was the first supplier to receive revised G8 certification and remains one of the few suppliers to have it. When operating in IMO-regulated waters, PureBallast 3 systems make maximum use of their power management and other capabilities.

To address differing needs in United States waters, there are standard and high-power versions of PureBallast 3 under USCG type approval. Standard systems, which utilize flow control in waters with low UV transmittance, are configured as for IMO-regulated waters and provide the option of minimized holding time when operating in USCG-regulated waters. The minimized holding time is just 2.5 hours and is only needed when crossing between Captain of the Port Zones. High-power systems are configured to allow full flow in the vast majority of United States waters.

Always at the forefront

No supplier in ballast water treatment is more committed or experienced than Alfa Laval.

Innovation built on experience

Alfa Laval is not only a global marine supplier, but also the most qualified, experienced and knowledgeable supplier in ballast water treatment. PureBallast was the world’s very first commercially available ballast water treatment system, launched originally in 2006.

Our pioneering work with marine biology and UV-based ballast water treatment goes back much further. Since the earliest days of discussion, Alfa Laval has been selected as a consultant on key panels involved in developing standards and educating the market.

Total support worldwide

Today Alfa Laval has a complete range of solutions for both newbuild and retrofit needs, built on our longstanding work with customers, authorities and scientific bodies. Shipyards, engineering companies and shipowners can expect clear and thorough documentation, as well as expert consultation. Shipowners will also find far-reaching ownership support, including complete services for cost-efficient peace of mind.

Everything Alfa Laval offers – from advice to parts and service – is readily available worldwide.
