Wärtsilä AQUARIUS® UV Ballast Water Management System (BWMS) provides robust technology for the treatment of ballast water using a simple two stage process involving filtration and ultra-violet (UV) irradiation, across the full range of ship operating and environmental conditions. The system uses no active substances, is easy to integrate and maintain, and is type approved according to the IMO Convention and has an Alternative Management System (AMS) acceptance certificate from the USCG. It has also been verified for explosion proof (EX) requirements and can therefore be used on-board hazardous areas. Wärtsilä works in close cooperation with its customers, our BWMS partnership program covers all stages from fleet evaluation to lifecycle support. Wärtsilä’s tailored turnkey solutions help minimize your environmental footprint, improve operational efficiency and enhance reputation. TECHNICAL OVERVIEW Aquarius® UV is a ballast water management system, providing a safe, flexible and economical process for the treatment of ballast water. Ballast water treatment with the Aquarius® UV system is achieved through a simple and efficient two stage process. Upon uptake the sea water is first passed through a back washing filter (1st Stage). The filtered sea water then passes through a UV chamber (2nd stage) where ultra-violet light is used to disinfect the water prior to entering the ballast tank. On discharge, water from the ballast tanks passes through the UV chamber only for a second time.
