    Executive Summary

    Xiaohongmen Water Reclamation Plant (XHM) was upgraded and expanded for sludge treatment by Advanced Anaerobic Digestion (AAD) with Thermal Hydrolysis Process (THP). From planning and designing in 2010-2014, to installing and commissioning in 2015-2016 and operating since 2016, the XHM project has
    exemplified the procedure of how THP was integrated in an existing plant for improving both capacity and performance of sludge anaerobic digestion. The operating performances were deeply analyzed. The AAD with THP has contributed to the carbon footprint reduction in line with Carbon Neutrality Plan in Beijing Drainage Group. Further optimization is also indicated.
