CHEMICAL-FREE BALLAST WATER TREATMENT FROM GEA

Thursday, September 6, 2018 

The BallastMaster marineX, which GEA presented at SMM in Hamburg, makes chemical-free ballast water treatment possible. The plant was developed by Trojan Technologies of Canada.

The BallastMaster marineX is a highly efficient mechanical and physical treatment system for ballast water treatment of different ship sizes. The GEA BallastMaster marineX is designed for a throughput of 150 - 1500 m³/h and is available as explosion-proof version. The two-stage system combines mechanical pre-filtration with subsequent disinfection of the ballast water by UV-C light. The system effectively disinfects organisms with a UV transmission value (UVT) of 44 percent and gets by completely without chemicals. It combines effective 32-μm filtration with subsequent UV irradiation for disinfection in one housing. This prevents germs or organisms from entering foreign ecosystems when the ballast water is drained. The effective differential pressure-controlled filter backwash (Full Flow) and the integrated, automated cleaning of the quartz tubes enable stable disinfection and the achievement of the IMO-D2 limits. The GEA BallastMaster marineX provides excellent process values especially in turbid water conditions, for example in rivers. Due to its compact design, it requires up to 50% less space than conventional systems. Its low power consumption and effective operating principle make it one of the best options for all types of ships.

In ballasting, the majority of organisms and sediment particles are removed by a mechanical filtration process. This prevents the deposit of particles in the ballast water tanks and improves the results of the second stage, the disinfection of the ballast water. The automatic backwash ensures thorough cleaning of the filters and thus enables effective treatment and a long period of use.

In the second stage, the pre-filtered ballast water is disinfected by UV-C radiation from TrojanUV Solo Lamps. During deballasting, the water bypasses the filtration (bypass) and is passed through the UV chamber again for treatment.

The GEA BallastMaster marineX is approved by the International Maritime Organization (IMO) with the type Approval G8 and has the approval of the Alternate Management System (AMS) of USCG for all water qualities: fresh water, brackish water and sea water.
