The floating ventilation stack
The target for the new 30 M steel stack was to minimize the nuisance odour from the new modernized sewage treatment plant inside the rock at Odderøya in Kristiansand.
But is it not a ordinary steel stack when you look at it - at distance it should ,so to say, be perceive as a floating stack. Therefore is the lower part of the corten stack covered with stainless steel plates as smooth as a mirror.
In order to maintain the smooth surface of the stainless steel plates a special drain system is developed mounted between the corten stack outer shell and the stainless steel plates.
