Environmental Services INTEGRATED BALLAST WATER TREATMENT With environmental sustainability becoming ever more critical, the effective and safe treatment of ballast water is an increasingly important issue. Today, the loading and unloading of untreated ballast water accounts for several thousands of marine species being moved from one ecological area to another, sometimes with disastrous results for fragile ecosystems. In an effort to address this situation, the International Maritime Organisation (IMO) adopted the Global Ballast Water Convention in 2004, mandating that ballast water must be treated prior to releasing it in another ecological zone. THE WÄRTSILÄ SOLUTION – COMPACT AND EASY TO INSTALL Wärtsilä’s Ballast Water Treatment (BWT) solution effectively meets the IMO requirements. Its revolutionary design integrates both UV irradiation and ltration in a single treatment unit. The treatment process within the system has two main steps, beginning with the ltering out of larger organisms or particles. The remaining organisms are then inactivated by ultraviolet (UV) irradiation. The Wärtsilä BWT 500i unit is designed for easy installation and operation, and its compact size makes it suitable for installation in most vessels. The optimization of both treatment processes in the integrated design results in lower running costs. A single unit can treat 500 m3 of ballast water per hour, and several units can be installed in parallel for higher ow rates.
