Wärtsilä AQUARIUS® EC
The Wärtsilä AQUARIUS® EC ballast water management system (BWMS) provides robust technology for the treatment of ballast water using in-situ electro chlorination, across the full range of ship operating and environmental conditions.
The Wärtsilä AQUARIUS® EC BWMS is a simple and efficient two stage process involving filtration and electro-chlorination (EC). During uptake, seawater is first passed through a 40 micron back washing screen filter to remove particulate, sediment, zooplankton and phytoplankton. Disinfection of the filtered sea water is then carried out using hypochlorite generated from the side stream EC process, and controlled by the BWMS control system.
Upon discharge, the ballast water bypasses the filter and any residual active substance is neutralised using sodium bisulphite, to ensure that the ballast water is safe to discharge back to the sea in full compliance with MARPOL requirements.
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 review and ship survey, through to the supply, installation, and commissioning of the hardware, and continuing with lifecycle after sales service and support.
