Atlantium Marine has installed its Purestream ballast water treatment technology installation on a Zim-operated containership as part of the shipboard testing phase
Atlantium Marine has announced that it has completed the installation of its proprietary UV-based ballast water management system (BWMS), Purestream, onboard a 3,854 TEU container vessel — Zim Qingdao — and is now in the shipboard testing phase to acquire IMO and USCG type approval.
Instead of drydocking, Atlantium installed the Purestream BWMS system while the vessel was in transit.
The Purestream system has a small footprint and design that allows for a separate-skid installation of the ballast filter, system components and the vertical-mounted UV unit in space constrained engine rooms.
Purestream uses filtration in combination with Atlantium’s medium pressure ultraviolet (UV) technology. The system is approved to operate at retention times of 24 hours or less following treatment of 100% of the maximum flow under water conditions with UV transmittance (UVT) as low as 40%.
Earlier this year, Atlantium announced the system was in the final stages of its approval process — the readiness evaluation and the land-based validation in accordance with the IMO BWMS Code and the USCG Ballast Water Discharge Standard (BWDS), with Lloyd’s Register (LR) as independent laboratory and Niva as the test facility in Norway.
Atlantium’s Purestream BWMS is designed to limit the operational restrictions of the ballast process by enabling the treatment of the worst water conditions with minimal to no retention time restrictions. This is accomplished using a unique approach to fully automate control, minimizing restrictions on the flow and enhancing the filter back wash mechanisms to prevent filter clogging.
According to Atlantium Marine, the Purestream ballast water treatment system offers a full complement of services including 3D and engineering services, documentation generation for class approval, manufacturing of all piping, platforms and support, wiring, adding indicators to the existing valves to record any bypass, and complete system installation, integration and commissioning.
