Sludge drying – a detailed expert guide
Sludge drying transforms sludge from an industrial waste product into a valuable resource. With the help of special machines and processes, industrial sludge as well as organic sludge, metal sludge and paper sludge are efficiently and decentrally converted into a compact mass with a low water content that can be used in a variety of ways.
What is sludge drying and why is it used?
Sludge drying is the process of removing water from sludge that originates from various industrial, agricultural or municipal processes. This process is crucial for reducing the volume, lowering transportation and disposal costs and safely reusing or disposing of the sludge.
Dried sewage sludge can be used as fuel, fertilizer or in the production of materials, thereby conserving resources and protecting the environment. However, it must first be subjected to the special process of sludge drying.
Can be implemented on site and economical – our sludge drying system
Modern systems such as ours work with a combination of contact and convection drying and are ideally suited for a wide range of applications. This sludge dryer is versatile and can be used for a wide range of sludges, from sewage sludge to biosludge and metal sludge.

Overview: The sludge drying process
The sludge drying process consists of several phases:
- Feeding the drying system
- Supply of heat and constant movement
- Removal of moisture
- Collecting the dried sludge
- Disposal or recycling
Dewatering and drying sludge – how the process works
The water is then efficiently removed from the sludge using hot air and contact heat in order to evaporate it. Energy consumption is minimized through the use of state-of-the-art technologies such as low-temperature drying. This process not only drastically reduces the water content to 10-30%, but also increases the quality of the dry substance.
Limitless possibilities for sludge utilization after drying
After drying, the processed sludge can be used in a variety of ways. It serves as a renewable energy source, is processed into ecological fertilizer or used as an aggregate in the construction industry. This further processing supports a sustainable circular economy and helps to conserve natural resources.

What is sludge drying?
Sludge drying, also known as sludge dewatering, is a process in which water is removed from the sludge to reduce its volume and facilitate its disposal or recycling. This reduces transportation and treatment costs.
Is sludge drying environmentally friendly?
Modern sludge drying technologies are designed to be environmentally friendly. They reduce emissions, prevent groundwater pollution and enable the recovery of resources, e.g. the use of dried sludge as fuel or fertilizer.
What technologies are used for sludge drying?
Various technologies are used for sludge drying, including centrifugation, filter presses, thermal treatment and biological processes. These processes aim to stabilize and dry the sludge and prepare it for safe disposal or reuse.
