Drying sewage waste for using waste heat

Sewage sludge deposits frequently pose difficulties for water treatment stations. Drying sludge may provide a solution. Dongding 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 the deodorization device, which reduce odour emissions to the set standards.And Dongding can simply install an deodorization device or deliver it with the equipment.

 

WHY DRY SLUDGE?

 

1. Making good use of residual heat during the entire year

2. Lower storage and transport costs

3. New sales and utilization possibilities

4. Hygienization and reduced emissions/odours

 

After dewatering the sludge, a dry matter percentage of between 18 and 22% will usually remain. After drying sewage sludge with a sludge rotary dryer, a dry matter content of 90% can be achieved.
