Description

The wastewater treatment plant in Bad Kissingen currently has a heat supply via a CHP plant and a boiler (both can be operated via digested and natural gas). In the future, the CHP plant will only be operated at night if no PV power is available. The supply of natural gas will also be discontinued. In order to ensure the heat supply in the future, a heat pump will be installed in combination with a wastewater heat exchanger. For this purpose, an appropriate shaft for the wastewater heat exchanger is erected by the AN and the underground pipelines are prepared by the latter. Heat pump and wastewater heat exchanger are then introduced from the AN of the LV in question and connected to the pipe system. Pumps, fittings and pressure compensation for the heating circuit between heat pump and wastewater heat exchanger are also created by this. In addition, a 4,000 l buffer tank, a fresh water station including a reservoir, as well as a pressure holding and treatment station for the heating water will be built by the AN of the LV in question. In addition, dismantling work and pipe construction work in the heating cellar have to be carried out by the AN. The extension of an existing sludge heat exchanger and the insulation of the newly constructed heating pipes must also be carried out. The commissioning of the entire heating system is also carried out via the AN.
