Techniques

Chapter 1: Techniques of the Swiss Combi System

The Swiss Combi System employs a unique combination of proven technologies to achieve efficient and environmentally friendly sludge treatment. The core techniques involved are:

1. Sludge Drying:

• Thermal Drying: The system utilizes a combination of hot air and heat recovery systems to evaporate moisture from the sludge. This method offers high efficiency and minimal energy consumption.
• Controlled Drying: Precise temperature and airflow control ensure optimal drying conditions, preventing over-drying and preserving the sludge's valuable properties.
• Odor Control: Advanced air pollution control technologies, such as biofilters and activated carbon adsorption, significantly reduce odor emissions during the drying process.

2. Pelletization:

• Mechanical Pelletization: The dried sludge is passed through a series of rollers and dies, which compact and shape it into uniform pellets. This process enhances handling, storage, and transportation efficiency.
• Granulation: In certain cases, the system incorporates granulation techniques to produce larger, more robust pellets. This increases stability and reduces dust formation.

3. Integration and Automation:

• Process Integration: The Swiss Combi System seamlessly integrates the drying and pelletization stages, ensuring continuous and efficient sludge treatment.
• Automation: Advanced automation systems control and monitor the entire process, optimizing performance and minimizing human intervention.
