Sludge Drying & Sewage Sludge Drying
Efficient Drying Solutions by Hans Binder
Sludge drying – particularly sewage sludge drying – is a key process in modern wastewater treatment, disposal, and recycling concepts. Rising disposal costs, stricter regulatory requirements, and an increasing focus on sustainability make efficient drying technologies indispensable today.
For decades, Hans Binder has been developing high-performance, energy-efficient drying systems specifically designed to meet the requirements of sludge drying and sewage sludge drying.
What Is Sludge Drying?
Sludge drying refers to the targeted reduction of the water content of sewage or industrial sludges using thermal processes. The aim is to prepare the sludge for further processing in a technically, economically, and environmentally optimal way.
Through drying, the sludge becomes:
- significantly reduced in volume
- suitable for transport and storage
- prepared for energy recovery or material recycling
Especially in sewage sludge drying, this process is essential to reduce disposal costs and comply with legal requirements.
Why Is Sewage Sludge Drying Essential Today?
Mechanically dewatered sewage sludge often still contains 70–80% water. Without further drying, this results in high costs for transport, storage, and disposal.
Modern sewage sludge drying enables:
- up to 90% volume reduction
- significantly lower disposal costs
- use of sludge as an energy carrier or valuable resource
Sludge drying transforms a disposal problem into an economic advantage.
How Does Thermal Sludge Drying Work?
In thermal sludge drying, heat is applied to the sludge in a controlled manner until the desired residual moisture content is achieved – typically between 10 and 30%.
Sludge Drying Process Sequence
- Feeding of mechanically dewatered sludge
- Uniform heating using process air
- Evaporation of moisture
- Discharge of the dried sludge
- Exhaust air treatment and heat recovery
➡️ Hans Binder relies on continuously operating belt dryers, which are particularly suitable for high throughputs.

Each system is individually tailored to the sludge type, throughput, and target residual moisture content.
Customized Plant Design as a Key Success Factor
No two sludge drying processes are the same. That is why Hans Binder focuses on:
- detailed analysis of sludge composition
- adaptation to existing infrastructure
- energy-optimized system design
- modular expandability
➡️ This results in tailor-made solutions with high economic efficiency and long service life.
