Antifouling

Am 24.11.2020 von 10:00 – 12:00 Uhr findet der "Virtuelle Biofouling Workshop" statt. Eine gute Möglichkeit, um die aktuellen Entwicklungen und Innovationen zum Thema Biofouling aus verschiedenen Perspektiven zu betrachten und zu diskutieren. Als Sprecher ist unter anderem Bernd Daehne aus unserem Hause mit dem Thema: "Testmethoden zur Erprobung innovativer Antifouling-Systeme" vertreten. Bis zum 22.11.2020 können Sie sich  HIER zum Workshop anmelden.    Das Programm: 10:00 Uhr: Begrüßung Dr. Susanne Neumann, Maritimes Cluster Norddeutschland e. V. 10:05 Uhr: Vorstellung der Marktübersicht „Lösungsansätze gegen Biofouling an Schiffsrümpfen“ Dr. Rainer Henking, EurA AG Eva von Soosten, Maritimes Cluster Norddeutschland e.

On Friday and Saturday, October 23 and 24, 2020, the jetty of the Norderney Sailing Club (SVN) was taken out of the water and cleaned. A filter system developed by Dr. Brill + Partner and the SVN was tested to remove biocides and paint residues from the antifouling paints. The four-stage filter system, consisting of sedimentation tank, fiber peat filter and activated carbon filter, was installed directly next to the "wash place" to filter the wash water on the spot and thus prevent the antifouling biocides from getting into the environment. In the course of the day, weak points of the system could be identified and eliminated. It turned out that the wash water was produced faster than it could be filtered. This was remedied by a 4 m3 container, which was spontaneously made available free of charge by the Onnen company and acted as a buffer storage. It also showed that the water produced contained significantly more suspended solids and sediments than expected. The suspended matter settled faster than expected on the felt mats used and hindered the flow of the water. As a result, the felt mats were replaced with gauze, which prevented clogging, so that the filter worked properly again. The filtered wash water was then discharged into the dock. Visually, a clear filter performance was visible, the analysis results are still pending.

Plastic waste and microplastics are probably the most discussed environmental topics at the moment besides global warming. On September 19, 2020, the staff of our Institute for Antifouling and Biocorrosion on Norderney participated again in the International Ocean Cleanup Day. The campaign was carried out together with the local BUND district group and the seventh-grade students from Norderney, who were also introduced to the habitat and waste problem. The Norderney public swimming pool and the technical services supported the action with man and machine. Fishing nets made of plastic accounted for the largest share of the stranded garbage. However, blankets and clothing from 342 containers of MS ZOE, lost at the beginning of 2019, were also found. In addition, numerous packages and containers, some from faraway countries, paint rollers, car spoilers, toilet covers and brushes, but also a whale rib and a message in a bottle were found. For more than 30 years, the US environmental organization Ocean Conservancy has been calling for the largest voluntary marine protection campaign - the International Coastal Cleanup Day (https://oceanconservancy.org/trash-free-seas/international-coastal-cleanup/).
