Application
Energy Generation Processes in Wastewater Treatment Plants
The sludge produced in the primary and secondary sedimentation basins is heated in a digestion tower to a temperature of between 35 °C and 40 °C. This airtight process, which lasts for up to 25 days, causes the sludge to decompose. Anaerobic bacteria break down the sludge into fermentation gas, water, and sapropel. The gas mixture created consists of around 70 % methane and 30 % carbon dioxide. In the gas cleaning plant, methane is extracted from hydrogen sulphide through a chemical reaction between the gas and cleaning solution. The gas is either burned off or temporarily placed in a storage tank for energy generation before being transported to a power plant or fed into a public gas grid.
Goal
Optimise anaerobic decomposition and safety
To optimize the anaerobic decomposition of sludge in the digestion tower, it is essential that temperature and pressure are monitored reliably. In addition, the formation and removal of foam by an agitator is monitored. This prevents the plant from being flooded with foam and stops pipe blockages while also increasing the gas yield. The quality of the gas produced is analysed so that any fluctuations in the heating value can be detected. This data indicates possible overheating in the pumps and may be used to regulate the combined heat and power plant located downstream. The pressure and fill level in the gas storage tank is monitored to prevent any overload in the tank and conduits and to stop gas from escaping.
