Comparison of land-based test set-ups for a ballast water management system

Two land-based setups were tested at different locations using the same combined treatment technologies, to assess the effect of different control and treated tanks condition as well as overall effectiveness of a ballast water treatment system. The test procedure included a five day storage period of organisms in the control and treated tanks as specifically advised in the type approval procedure for shipboard and land-based tests described in the IMO Guideline ‘G8’. The configurations and materials of control and treated tanks used in each test location were different resulting in invalid test results at one testing location.
