The dryer in the Wärtsilä Bio-Sludge Treatment system can process all the sludge from wastewater and food waste before incineration. The purpose is to reduce the volume by drying. A cruise ship produces large quantities of wastewater and food waste. This waste must be treated to comply with the environmental requirements for no pollution at sea.
The process increases the dryness of the waste to a high level of dry solids. Dried is stored in the dry waste silo before incineration.
In addition, the new agitator design reduces the operational requirements. The design of the agitators/blades within our dryer, prevent the chewing gum phase effect, and the creation of large stones. Using this new design of agitator removes the unnecessary task of cleaning and removing large un-dried bio waste stones which can take up to 3 days to complete.
