Wastewater facility opens in Kiel

04-TUI-Cruises-Schiffe-am-Ostseekai-Foto-Port-of-Kiel-1A ship facility has opened in Kiel which increases current wastewater reception capability tenfold to as much as 300m3 an hour.

The facility went into operation at the Port of Kiel’s Ostseekai Cruise Terminal this month and is believed to be one of only a few port facilities that can handle such large volumes of wastewater from ships. Dr Dirk Claus, managing director of the Port of Kiel, said: “We are investing in a cleaner Baltic.

This capacity increase is Kiel’s contribution to marine protection and meets regulatory demands which are not even due to take effect until 2021.”The facility was built at the terminal during a six-month period and incorporates several hundred metres of pressure resistant pipes of 225mm diameter, as well as eight junction points, aid parallel to the ship berths. The pipes flow into storage containers which have capacities of up to 75m3 and are fitted with waste-water analytical and treatment technology.

By using compressed air and adding ozone the water is aerated in fine stoneware pipes. If required, the pH value of the water can be regulated by feeding in sodium hydroxide solution. The compressed air connections are fully sealed while filters and adsorbers eliminate hydrogen sulphides in the facility itself. Cleaned exhaust air is discharged through a chimney.

The treated ship wastewater is then pumped into compressed air pipes, fed to the city sewage works in Bülk and cleaned.From 2021, all cruise ships and from 2019 all new ships, must dispose of all their wastewater in port and can only do so on board ship when regulatory standards are adhered to.
