PureBallast 3 -edut

<p>Ainutlaatuinen ominaisuuksien yhdistelmä nostaa PureBallast 3:n muiden painolastivesien käsittelyjärjestelmien yläpuolelle.</p>

Superior performance in any waters

PureBallast 3 offers unmatched biological disinfection performance in any type of water: fresh, brackish or marine. This includes water in liquid form at frigid temperatures. Even in low-clarity waters with UV transmittance as low as 42%, the system can perform at full flow.

As a result, 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.


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 diameter is 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.

Ex configurations are simple as well, since the power supply can be placed outside the hazardous zone.


A flexible offering

Alfa Laval’s PureBallast 3 offering lets you take full advantage of opportunities in meeting IMO and U.S. Coast Guard (USCG) legislation.

Upgrading to USCG type approval

For future-proof security, PureBallast 3 gives you flexible options if a later change in operating patterns requires you to be able to deballast in United States waters. Vessels that initially installed PureBallast 3 for use only in IMO-regulated waters can easily upgrade to a version of the system with type approval from the USCG.

This is also an important consideration when determining how your choice of treatment system will affect the resale value of your vessel. A vessel that does not offer the potential for USCG type approval will be difficult to sell to any buyer who wants to operate in this key market..

Compliance in all waters

The more waters your vessel has access to, the more business it can bring you.

Consider all water conditions

While marine and brackish waters are the focus for most ship owners, three-water certification is not only for rivers or the Baltic and Great Lakes. Many ports considered brackish are actually farther from the marine end of the transition zone and closer to fresh water. To reach them, you need a system like PureBallast 3, which can treat fresh water without salt or chemical dosing.

Likewise, some ports have near-zero temperatures or low-clarity water. Although UV transmittance levels in harbours usually range from 90% down to 60%, they can sometimes fall even lower. PureBallast 3 handles liquid water at frigid temperatures and can perform at full flow where UV transmittance is as low as 42%.

Safeguarding efficiency

The less time and energy you devote to ballast water treatment, the more you have for doing business.

Keep your operations moving

The ability to ballast or deballast efficiently is important to your vessel. However, many UV-based treatment systems must reduce their flow in harbours with low-clarity water. This is a result of low UV transmittance which may be further impaired by ineffective UV lamp cleaning.

By contrast, PureBallast 3 can operate at full flow where UV transmittance is as low as 42%. Its effectiveness is maintained by automatic Cleaning-In-Place (CIP), which removes UV-impairing build-up – without effort from the crew or risk of scratching the lamps.

When sailing under most conditions in IMO-regulated waters, PureBallast 3 can operate at just half its potential power, ramping up only for the most difficult low-clarity waters.
