Wärtsilä AQUARIUS® UV
The type approved Wärtsilä AQUARIUS® UV ballast water management system (BWMS) provides robust technology for the treatment of ballast water using ultra-violet (UV) irradiation, across the full range of ship operating and environmental conditions.
The Wärtsilä AQUARIUS® UV BWMS is a simple two stage process involving filtration and UV irradiation. During uptake, seawater is first passed through a 40 micron back washing screen to remove particulate, sediment, zooplankton and phytoplankton. Disinfection of the filtered sea water is then carried out using medium pressure UV lamps, and controlled by the BWMS control system.
Upon discharge, the filter is by-passed but the ballast water is again disinfected with UV treatment before safe discharge back into the sea.
By virtue of its modular design, the system’s inherent flexibility allows application across the full range of ship types and sizes, for both the new build and retrofit markets. Wärtsilä offers customers a range of flexible supply options, from the BWMS equipment only, to a full ‘turnkey’ service covering all phases, from the initial survey through to the supply, installation, and commissioning of the hardware, and continuing with lifecycle after sales service and support.
