Secure and Lasting Thermal Sewage Sludge Utilisation
Benefits of the sludge2energy Process
The sludge2energy system is a sustainable solution which provides security of thermal sewage sludge utilisation. The energy self-sufficient sludge2energy system for sewage sludge utilisation is based on the combination of a sludge dryer and subsequent incineration in a fluidized bed furnace.
This enables operators of sewage treatment plants to achieve sustainable waste management through independent utilisation of their sewage sludge and other residual materials, unaffected by the cost development for utilisation or co-incineration in third-party plants.
The innovative sludge2energy process offers:
- Efficiently combined sewage sludge drying and thermal utilisation in a fluidised bed furnace
- A wide variety of municipal sewage sludges can be utilised thermally due to an efficient use of energy, without the need for any external energy
- Individual planning, adaptable to suit customer-specific requirements
- Compact, modular and functional design with minimum space requirements
- Low invest and operational costs due to the optimised concept of thermal drying and utilisation
- Optimal sewage sludge quantity and mass reduction
- Minimised expenses and costs for sewage sludge transport
- Long-term cost certainty and disposal safety
- Dry flue gas cleaning process without generation of wastewater
- Optimized flue gas cleaning with regard to various customer requirements (site requirements, phosphorus recovery)
- Low pollutant emissions, significantly below legal limits
- Fully automatic operation 24 h/d, 7 d/week with a high plant availability of 8,000 h/a
- High flexibility of sewage sludge utilisation and the processed sludge
- Production of phosphorus-rich sewage sludge ash and optional phosphorus recovery
- Optional power generation taking into account specific individual conditions and plant size
