The Ballast Water Testing Devices were proven in addition to ballast water with seawater during the expedition across the Atlantic Ocean.
In the Mindelo’s harbour water were few microorganisms for port conditions - only 30 cells/ml in the size range of 10-50µm. If this water would be ballast water, it would need to be treated according to IMO. The amount of microorganisms was under 1 cell/ml water outside of the harbour, because of few nutrients. If this water would be ballast water, it would not need to be treated according to IMO.
The 10cells was able to detect both statuses certainly. Using the 10cells customers are able to know the quality of ballast water.
