SHORT DESCRIPTION
The Modau group wastewater treatment plant is operated by the Modau Wastewater Association and treats wastewater from the town of Ober-Ramstadt and the municipality of Mühltal. The plant is a classic activated sludge plant with anaerobic sludge stabilization.
The existing 20-year-old CHP units with an output of 50 kWel and 90 kWth had exceeded their economic service life and needed to be replaced. First, a variant study was carried out to determine the optimal module size in terms of electricity and heat generation, taking into account the subsidy situation. As a result, a new CHP plant with the same output as the existing plant was built. The emergency gas flare had already been replaced in advance. The CHP plant went into operation in June 2023.
