PureBallast 3 solutions for bulkers

Bulkers differ from other vessels in their ability to transport both dry and liquid cargo – which they often load and unload at different speeds. Their ballast water flow needs can be very small or very large, but they may not be the same during ballasting and deballasting. Alfa Laval PureBallast 3 offers solutions for all bulker types, and Alfa Laval has the bulker-specific experience to support the most complex bulker projects.


Adapting to bulker flow needs

Bulkers often load their cargo at twice the rate they unload it, which means deballasting occurs at twice the ballasting speed. The PureBallast 3 bulker-fit configuration addresses this by dimensioning the reactor and filtration capacities for differentiated flows. Not only does it reduce OPEX and the already small system footprint, it also removes a significant amount of CAPEX.


The choice of bulker customers

The number of customers choosing PureBallast 3 for ballast water treatment on their bulkers continues to grow.


Columbia Shipmanagement
first with bulker-fit

Columbia Shipmanagement will be the first to install PureBallast 3 systems with bulker-fit configurations. The savings in weight, footprint and equipment cost give the company further reasons for choosing UV ballast water treatment over electrochlorination.

Answers for your bulker’s needs

A wide range of system advantages and dedicated technical solutions make PureBallast 3 the ideal choice for ballast water treatment on bulkers.

Handling large ballast flows

Your bulker may require up to hundreds of thousands of tons of ballast water – which means large ballast water flows. PureBallast 3 handles even very large flows with a small footprint and low power consumption, thanks in part to a 1500 m3/h reactor size. Single systems can handle up to 3000 m3/h, while dual systems can be used for coverage up to 6000 m3/h.

Simplifying retrofit installations

Existing bulkers need to be retrofitted with ballast water treatment systems by the time of their next renewal survey. However, they seldom have space allotted for it in their design. PureBallast 3 Compact Flex handles most flows and is flexibly built with loose components, making it the ideal system for saving space and resolving bulker retrofit challenges.

Skid-mounted for smaller bulkers

If you have a smaller bulker, there’s no reason to make big work of installing a ballast water treatment system. PureBallast 3 Compact is a convenient, skid-mounted solution that’s specially designed for smaller bulkers and other vessels with flow needs of 32–300 m3/h. Delivered as a skid-mounted module, it minimizes both footprint and pipework.

Minimized holding time in US waters

Many bulkers operate in coastwise service in USCG-regulated waters. If you have a relatively short time between United States ports, long ballast water holding times aren’t an option. PureBallast 3 now has a minimized holding time of just 2.5 hours – which is only needed when crossing between Captain of the Port Zones.

Service to keep you fit

Installing a ballast water treatment system is only the first step in staying compliant. The regulations demand a whole range of annual service actions. Even so, one package is all that you need. With the PureBallast Compliance Service Package, our experts take responsibility for your PureBallast system’s health.
