Overview of Roediger Sewage Sludge Drying Plant (EDZ-Method)

The Roediger Sewage Sludge Drying Plant utilizes the EDZ-Method, which combines solar and waste heat to dry dewatered sewage sludge to over 90% dry solids content. This method is efficient and cost-effective, transforming sewage sludge into a viable alternative fuel.

Key Advantages

High drying performance through solar houses equipped with floor heating systems.
Evaporation of approximately 2.5 - 3 tons of water per square meter annually at low temperatures.
Innovative technology ensures no adhering, no dust accumulation, and low maintenance.
Fully-automatic operation from infeed to truck loading.

Technical Specifications

Wave-like sludge arrangement increases drying surface by 19%.
Fuel granulate produced has an energy content of 9 - 12 MJ/kg, comparable to wood pellets and brown coal.
Approximately 2.5 tons of sewage sludge can substitute 1 ton of mineral coal, reducing CO2 emissions.

Design and Construction

Simple, sturdy design with automatic infeed and dust-free discharge systems.
Durable materials used, including double-layer plastic foil and optional glass material.
Floor heating system integrated into concrete slabs for efficient drying.

Additional Services and Options

Process control systems with Profi-bus interface for integration with existing systems.
Remote monitoring and teleservice options available.
Service agreements and special design options offered to support plant owners.

Utilization of Waste Heating

Various heating sources can be used, including block-type thermal power stations and heat pumps.
