Non-native aquatic species can be introduced in new areas through emptying of the ballast tanks. These introductions induce a high impact on health, economy and environment. This is considered by the International Maritime Organization (IMO): the Ballast Water and Sediments (BMW Convention) entered into force on 8 September 2017 and opens the market for ballast water treatment. The major contribution and novelty of this study is to show successful ballast water treatment using an ultrafiltration process at industrial scale with a high technological readiness level, in order to show the applicability of the ultrafiltration processes for ballast water treatment. Another aim is to compare UV and ultrafiltration treatments applied to fresh water and seawater, from an economic perspective. This comparison accounts for the positioning of the treatment and the specific constraints associated to this positioning. The best membrane processes and the operating conditions were determined for fresh and seawater.
