Fjell dryer solutions for municipal sludge.
Part drying or scalping
In Fjell Turbo Disc (TD) Dryer. We increase relative portion of dry matter (DM) on wastewater from approximately 20% to 40% for the sludge to be fed directly to incineration.
In Fjell Turbo Disc Dryer. Together with a mixing system we can increase DM up to approximately 93%. Important nutrients such as nitrogen and phosphorus will remain in the sludge. Such sludge is useful as a basis in fertilizer production.
By using Fjell TD dryer together with our patented process solution, the steam consumption can be reduced by up to 40% compared to a standard dryer.
