Cost-Effectiveness and Ecological Benefits
Utilising domestic energy from wastewater as an alternative to fight global warming and increasing energy prices.
The target group of energy consumers lies in the range of 70 kW effective output and upwards. This corresponds to a required amount of wastewater of approx. 15 l/s. The annual energy savings achievable lies at up to 50 percent. Very short pay back times result due to the clear investment costs of two to three times a conventional energy system.
Potential energy consumers can be the following:
- Municipal buildings
- Residential areas
- Administration buildings
- Industrial plants
- District and local heating grids
When one uses energy from wastewater, one also avoids burning fossil fuels and thus significantly reduces CO2 emissions. The magnitude of substituting this energy with that from oil or gas lies in the range of up to 70 percent.
Material of Value: Wastewater
According to the renewable energy heating law dated 18 October 2007, a obligation to use results from § 4/3 for the utilisation of environmental energy (heat extracted from water bodies).
