Alfa Laval Pureballast 3 Matches Differentiated Ballasting/Deballasting Flows
Alfa Laval PureBallast 3 bulker-fit configuration can be used by Bulk carriers that is particularly used to their flow needs.
Though the bulker-fit configuration provides savings in footprint, installation, OPEX and particularly CAPEX, yet it does not compromise the high performance, easy operation and global service coverage PureBallast 3 is known for.
A large number of ship owners are preferring UV ballast water treatment over electro chlorination, for large ballast water flows also. The benefits such as chemical-free operation, zero corrosion risk and efficiency at low salinities and temperatures seem a lot more attractive because of the better footprint and consumption of energy that is provided by the present UV treatment. However, only a few bulkers have moved to UV till now.
“Bulkers have a unique ballasting and deballasting profile, because they load and unload at significantly different rates,” says Peter Sahlén, Head of Alfa Laval PureBallast. “The PureBallast 3 bulker-fit configuration differentiates the two flows, which reduces CAPEX while preserving the many other advantages of UV treatment, such as lower OPEX. That gives bulker owners a strong alternative to electrochlorination.”
No ballasting overcapacity means less CAPEX. The cargo is loaded at twice the speed of unloading, meaning deballasting takes place at twice the ballasting speed. This problem is removed by the PureBallast 3 bulker-fit configuration by measuring the capacity of reactor and filtration independently. It is dimensioned for the slower ballasting flow because the filter stage is required only during ballasting. This leads to the reduction of OPEX and the already small system footprint and also removes ballasting overcapacity and a small investment cost.
“The PureBallast 3 bulker-fit configuration matches UV strengths to bulkers’ actual flow needs,” says Sahlén. “Bulker owners who have seen electrochlorination as the only fit for their operating profile now have cost-efficient access to the substantial advantages of UV treatment.”
Focus on vessel-specific solutions
The PureBallast 3 bulker-fit configuration is a part of the broad plan of Alfa Laval in ballast water treatment, that aims to offer reliable compliance with the least limitations in both installation and operation. Widely, it means offering solutions that are adaptable by vessels. In addition to this, a PureBallast 3 deckhouse solution has also been introduced. It has booster pump unit that will eliminate issues related to space and pressure on tankers without a pump room.
“Ballast water treatment is not a one-size-fits-all application,” says Sahlén. “PureBallast 3 is already the most adaptable ballast water treatment solution on the market, and we will continue to build our offering with specific answers for different vessel types.”
