The MIR-D system was implemented in Changsha Wangcheng District Treatment Plant in November 2020 for a sludge direct drying dewatering project. The system processed 50t/d of sludge with 80% moisture content from one production line and reduced it to 30-40% moisture content.

The project showed the benefits of the MIR-D system for sludge treatment, such as its efficiency, reliability and cost-effectiveness. It also paved the way for the future upgrade of the sludge treatment process of the plant.
