This website provides public information about the EcoSeaSafe project which aims at developing a sustainable and cost effective ballast water treatment technology. The project was initiated by Sorbwater Technology AS and financed by the funding scheme "Research for SMEs" within the EU 7th Framework Programme.

Official start date of the project was November 1st 2010, and the duration will be 24 months.

Project Description

Transfer of invasive marine species via ballast water, is a major global ecological and economic problem. The EcoSeaSafe project is developing a ballast water treatment system securing inactivation of microbial invasive species in ballast water.

Project Results

Development of a new pulse generator

The reactor applied in the laboratory investigations had to be up scaled and upgraded to include automatic registration of input and output values of voltage/current. Therefore, a dedicated pulse generator has been developed  by Labor designed for application in the trials of the pilot plant.

Development of the reactor electrodes

Based on results of preliminary laboratory investigations, a set of electrode grids have been developed and manufactured using 4 different alloys developed in the project.  The electrodes haven been subjected to functionality tests at TI using fresh seawater transported from the Oslo Fjord. Sea water was extracted at 60 m depth and with temperature of 8o C.  Before the tests, the seawater was filtered through a 10 µm filter to remove particles and then through a Carbon filter to remove organics.  After filtration, the water was filled in a 100L tank and heated to ambient temperature.
