Performance and peace of mind

Alfa Laval has the technology, knowledge and experience to ensure your compliance. Besides leading in system performance, we have provided biological and technical competence on key panels involved in developing standards and educating the market.

Compliance in any waters PureBallast 3 complies wherever your vessel sails. The system is type approved and certified by both IMO and the USCG, and it avoids the limitations experienced with other systems. As an example, different ports have different water conditions. While the clear water in Singapore can be treated by almost any system on the market, the waters of Shanghai or Bremerhaven are technically challenging. Many systems cannot comply in these ports or

others like them – or will require your vessel to slow its operations significantly. PureBallast 3 is unaffected by salinity and can treat fresh, brackish or marine water, regardless of water temperature. Using one of the most effective filters on the market, it removes high concentrations of suspended solids. It also outperforms other UV systems in challenging waters, handling UV transmittance levels as low as 42%. As a result, PureBallast 3 complies in more ports worldwide than any other system.

Chemical-free treatment Alfa Laval PureBallast 3 treats ballast water without the use of chemicals. It is approved according to the IMO revised G8 guidelines and involves no active substances that would necessitate G9 approval. In other words, no chemicals are required for treatment and no chemical compounds are formed during the treatment process. Thus, there is no increased risk of ballast tank corrosion, no ventilation needed and no chemical discharge. No safety equipment or storage space is required, and there are no supply logistics to consider when planning your vessel’s route. Your vessel’s operations are simplified. Cleaning of the UV reactor is performed with a non-toxic and biodegradable cleaning solution. For further information regarding the cleaning agent, a material data safety sheet can be provided.

Updated G8 compliance and beyond PureBallast 3 is compliant with the revised IMO G8 guidelines, which were developed to harmonize the type approval process and ensure its robustness. The system exhibits superior performance under challenging test conditions, which also safeguards compliance during Port State Control sampling. Your ballast water treatment system will need to meet the discharge standards for as long as you own the vessel. By choosing PureBallast 3, you choose a supplier with a century-long track record and a system that has been developed not only to pass the certification tests, butn also to comply with discharge standards under real conditions– today and throughout the vessel’s lifetime.

Lowest cost of ownership

Your ballast water treatment system should last as long as your vessel, which makes it important to look at its total costs. From installation to operation, PureBallast 3 is the cost-effective choice.

Cost-saving project management The largest cost of a ballast water treatment system is not the system itself, but rather its engineering and installation. This is especially true in a retrofit project, which can involve many parties and high complexity. Alfa Laval provides experienced project management, built on a decade of installations and thousands of retrofit projects. By working closely with all parties, our team lets you avoid engineering mistakes and delays that can drastically increase your project cost.

Durable system construction Materials impact the lifetime and maintenance needs of components. Higher quality increases upfront costs, but it ensures fewer problems and replacement costs over time. This is why Alfa Laval uses high-grade materials for all key PureBallast 3 components. In a warm engine room, for example, marine water can easily corrode

28

a UV reactor of 316L steel, creating a replacement need in as little as five years. PureBallast 3 reactors are made of super austenitic stainless steel, a material designed for seawater applications. Likewise, non-corroding bronze-aluminium is used for the filter body.

Energy-saving power management PureBallast 3 minimizes energy-related costs with automatic power management. This is available whenever operating in IMO-regulated waters, including when USCGcertified systems operate outside the United States. With this feature, PureBallast 3 runs at just 50% of its potential operating power in most situations. It can then ramp up to full power for the most challenging waters.

Easily maintained performance Maintaining PureBallast 3 involves little time or cost, and the most important maintenance is automatic. A Cleaning-In-Place (CIP) system keeps the reactor sensors and lamp sleeves free from performance-reducing fouling. In contrast to wiper-based cleaning systems or manual cleaning, the circulation of inexpensive and biodegradable CIP fluid involves no moving parts or risk of scratching the sleeves. The technique prolongs sleeve life while avoiding your biggest potential cost: non-compliance due to degraded performance.

Ease of installation and operation

PureBallast 3 is designed to make life simple, both for those who engineer and install it and for the crews that will operate it over your vessel’s lifetime.

High vessel compatibility PureBallast 3 is an excellent match for nearly any vessel. Single systems handle ballast water flows of 32– 3000 m3/h, and multiple systems can be used for even larger capacities. For installation in explosive environments, components with ATEX or IECEx certification can be used to create a PureBallast 3 Ex system. Space-saving inline design PureBallast 3 is a modular solution with an inline design in which the major components are incorporated into the ballast water piping. This creates a highly flexible system with a small footprint, which is especially important when engineering a retrofit. Retrofits in particular can benefit from PureBallast 3 Compact Flex, which is the answer to space and flexibility concerns. With its plug-andplay concept, PureBallast 3 Compact Flex minimizes the costs and time for both engineering and installation. Delivered as loose components for complete installation freedom and a truly minimal footprint, PureBallat 3 Compact Flex is ideal for most vessels and is suitable for flows of 32–1000 m 3 /h. For flows of 32–300 m3/h, PureBallast 3 can also be delivered as a ready-configured, plug-and-play module: PureBallast 3 Compact. PureBallast 3 Compact systems are not only compact, but also easy to install due to minimized pipework.

Vessel-specific solutions Each vessel has its own challenges, especially if it was not designed to have a ballast water treatment system on board. Not only is PureBallast 3 highly flexible, Alfa Laval also has specific Pure-

Ballast 3 solutions for individual vessel types. These support and simplify installation, making it possible for the vessel to continue operating at the performance it was built for. Deckhouse solutions for tankers are an excellent example. Delivered pre-assembled, including the PureBallast 3 Ex system and all internal piping and wiring, a deckhouse enables topside installation when there is no pump room. If the elevated position means the ballast pumps on board do not offer sufficient pressure, a booster pump unit (BPU) can be integrated into the deckhouse to ensure proper system function. The BPU provides sufficient pressure at all times, which eliminates the need to modify the existing ballast pumping system.

Strong but flexible project management No two installations are the same, especially in retrofit projects. Drawing on a decade of retrofit experience, Alfa Laval takes responsibility and understands the importance of adapting to change. Our project management combines local presence with global strength. We can work with your engineering department and chosen yard, or we can secure all necessary competencies from our network of skilled partners. Likewise, we can meet your existing docking schedule or arrange for installation during your voyage. As a global organization with strong logistics, we can even move with your project if your trading routes change prior to docking.

Simple, automatic operation Once installed, PureBallast 3 is fully automatic and operates in the background. Together with Alfa Laval crew training, this minimizes the risk of non-compliance as a result of crew error. Remote panels or integration with the ship’s control system allow PureBallast 3 to be overseen from the bridge, cargo control room or elsewhere.

Limited maintenance Maintenance of PureBallast 3 is limited to a few simple tasks at regular intervals. If desired, Alfa Laval can take responsibility for the whole system, performing annual maintenance, calibration and upgrades as part of a service agreement. In the event of an unplanned service need, Alfa Laval’s global service network is always close by.
