Turbocompressors for Wastewater Treatment Plant

This case study details the implementation of turbocompressors at the wastewater treatment plant in Sögel, Germany. The plant, which serves a population equivalent of 66,500, has undergone significant upgrades to manage both domestic and industrial wastewater. Previously reliant on rotary piston blowers, the facility faced challenges with unit failures and fluctuating loads due to a high percentage of industrial wastewater. To address these issues, the plant opted to install five HST turbocompressors, which are centrally controlled and can adjust to varying operational demands. The benefits observed include a reduction in specific energy consumption by up to 50%, lower heat generation, decreased noise levels, and minimal maintenance requirements compared to the previous system. The case study also highlights the advanced design of the HST turbocompressor, which features magnetic bearing technology and a high-speed motor. Overall, the installation has led to significant operational improvements and cost savings for the plant.
