Fjell Municipal Sludge Treatment

Municipal wastewater treatment plants (MWWTP) - Sludge dryer for Part or Full drying in Sewage treatment plant

Energy efficient sludge drying systems for municipal wastewater sludge

We provide state-of-the-art technology and proven solutions for sludge drying from municipal wastewater treatment plants - optimal recovery of sludge for use as fertilisers or fuel in incineration plants.

  • Energy consumption can be reduced by up to 40% compared to a standard drying system using our patented process solution combined with our Fjell TD dryer.

Our Fjell Turbo Disc Dryer has proven to operate in extreme conditions under strong wear and tear since the first unit was installed in 2001.

  • Biogas digestate and municipal wastewater sludge are known to be challenging to dry because of their tendency to transform to a glue phase.
  • Municipal wastewater sludge is an extremely tough application causing severe wear and tear on the drying equipment.

Fjell Sludge drying solution for sewage treatment plants

Sludge dryer or thickening results in reduced weight and volume, easy recovery and sludge stabilisation.

Sludge thickening (Part drying) or scalping for Waste to Energy and Sludge incineration plants.

  • Our Fjell Turbo Disc (TD) Dryer increases the dry matter (DM) in the wastewater sludge from 20% to 45%.
  • The sludge can be fed directly to a sludge incineration plant to generate carbon neutral energy (WtE).

Full drying for utilisation of nutrients

  • Our Fjell Turbo Disc (TD) Dryer combined with a mixing system can increase dry matter (DM) up to 93% whereby important nutrients such as nitrogen and phosphorus will remain in the sludge or digestate. The dried sludge is sanitized and storage-stable - in a bigbag system or sludge container. The dried product is a useful basis in fertilizer production.
