Alfa Laval has unveiled its third generation of its chemical-free ballast water treatment system PureBallast 3.0. The system is said to save both space and energy and will be on display at the upcoming Europort exhibition.
PureBallast has been developed in cooperation with Wallenius Water and was first launched in 2006 as the world’s first commercially available ballast water treatment system.
Energy Savings
While based on the same technology as its predecessors, PureBallast 3.0 has a completely new reactor design that minimises power consumption with a minimum energy savings of thirty per cent.
Dimming Function
In clearer waters with good UV transmittance a dimming function can be used. In such conditions, less energy is needed to neutralise the organisms present. In this mode, energy savings can reach sixty per cent.
Space Savings
The new reactor design is more compact. Where previous PureBallast reactors handled 250 m3/h each, individual 3.0 reactors can handle either 300 m3/h or 1000 m3/h.
Using the larger reactor, which is not much bigger than the original 250 m3/h version, the footprint of a 1000 m3/h system is cut in half. The bigger the system, the bigger the space savings.
Cutting Installation Time and Increased Flexibility
In addition, fewer reactors and lamp drive cabinets need to be installed, cutting installation time and reducing pipework.
Furtermore, the lamp drive cabinets are no longer attached to the reactors they serve. They need to be placed within 150 m, which simplifies the design of EX systems, since the power supply is easy to place outside the hazardous zone and it saves space in the engine room.
PureBallast 3.0 will be on display at Europort, Rotterdam, stand 8212 in hall 8 from 5 – 8 November.
