Treatment Processes Driving Performance at the Sludge Treatment Plant
The facility incorporates an innovative sludge digestion system designed for stability, reduced chemical use, and enhanced biogas yield. Key steps include mechanical thickening, anaerobic digestion, biogas treatment, nutrient removal, and safe biosolids handling — ensuring optimal interaction with upstream wastewater treatment operations.
Biogas Utilisation and Energy Recovery at the Sludge-to-Energy Plant
As a flagship sludge-to-energy plant, the facility transforms digestion biogas into clean power, supporting 67,000 kWh/day of energy production. This reduces reliance on grid electricity and enhances the sustainability of Beijing’s municipal sludge treatment plant operations.
Environmental Impact and Long-Term Sustainability
The sludge treatment plant transforms raw sludge into stabilized biosolids, enabling safe disposal and reducing the environmental footprint of Beijing’s wastewater treatment ecosystem. Its energy recovery systems lower carbon emissions and showcase how circular economy design can reshape urban sanitation.
Strengthening Beijing’s Leadership Among Wastewater Treatment Cities
With its scale, technology, and performance, the XiaoHongMen sludge treatment plant reinforces Beijing’s leadership in advanced wastewater treatment solutions. The project sets a benchmark for integrated sludge management and positions WABAG at the forefront of global sustainable treatment infrastructure.
