BALLAST WATER MANAGEMENT• Wärtsilä AQUARIUS ® UVWärtsilä AQUARIUS ® UV Ballast Water Management Systems (BWMS)provide robust technology for the treatment of ballast water usingultra-violet (UV) irradiation, across the full range of ship operating andenvironmental conditions.The Wärtsilä AQUARIUS ® UV BWMS uses a simple two stageprocess involving filtration and UV irradiation. During uptake, seawateris first passed through a 40 micron backwashing screen to removeparticulate, sediment, zooplankton and phytoplankton. Disinfection ofthe filtered sea water is then carried out using medium pressure UVlamps, and controlled by the BWMS control system. Upon discharge,the filter is by-passed but the ballast water is again disinfected with UVtreatment before safe discharge back into the sea.The system has a modular design enabling it to be arranged tosuit conditions onboard the ship. The system can be designed and14
