Energy efficient drying of sewage sludge
Drying sewage sludge using our plated belt drying system
Sewage sludge deposits frequently pose difficulties for water treatment stations. Drying sludge may provide a solution. Dorset has practical experience with the drying of sewage sludge.
This is a sustainable and cost-effective way of recycling sewage sludge into fuel. Our sludge dryers are frequently provided with Dorset Air Washers, which reduce emissions to the set standards.
As a manufacturer of air washers, Dorset can simply install an air washer or deliver it with the machinery. We offer total turn-key solutions including heat recovery, safety, storage and air cleaning equipment.

Benefits of the Dorset dryer
the best value for money
Low energy consumption
Highly compact and flexible
Requires little maintenance
Fully automatic operation without supervision is possible
Dewatered sludge can be dried without intermediate treatment
Low dust generation through low air speed
Why dry sludge?
- Making good use of residual heat during the entire year
- Lower storage and transport costs
- New sales and utilization possibilities
- hygienization and reduced emissions/odours

Possibilities for using dried sewage sludge
Dried sewage sludge is regularly used as a fuel or biosolids
After dewatering the sludge, a dry matter percentage of between 18 and 22% will usually remain. After drying sewage sludge with a Dorset Dryer, a dry matter content of 90% can be achieved.
