Jiangsu Municipal Wastewater Treatment Plant

At a municipal wastewater-treatment plant in Jiangsu, Sujing CO2 integrated heating-and-cooling units serve the sludge-drying stage. The system recovers part of the dryer waste heat, supplies cooling for circulating-air dehumidification and provides constant 90 C heat for sludge drying. Multi-compressor parallel architecture delivers megawatt-scale heating and cooling capacity with an overall efficiency of at least 6.0 from one system.
