At a centralized municipal wastewater treatment plant handling the complete domestic wastewater load of a densely populated city, three high-capacity decanter centrifuge systems were integrated to achieve high-efficiency dewatering of municipal sewage sludge.
The primary objective of the project was to minimize the moisture content in high-volume municipal sludge, significantly reducing total sludge volume and establishing a sustainable, cost-effective infrastructure for the city's environmental disposal operations.
Technical Details and Field Performance
Municipal wastewater plants are critical public infrastructure subject to seasonal load fluctuations and with zero tolerance for downtime:
3-Unit Synchronized System Architecture: Positioned in accordance with the facility's total hydraulic flow rate, our three high-throughput decanters effortlessly handle the total treatment capacity via a synchronized automation framework.
24/7 Continuous Operation Reliability: To handle the city's round-the-clock wastewater load, an uninterrupted operational infrastructure equipped with heavy-duty bearing, bowl, and drive configurations was delivered.
Key Deliverables and Added Value
Maximum Cake Dryness and Low Logistics Costs: By maximizing sludge volume reduction, significant cost savings were achieved across off-site transport, drying, and disposal operations.
High-Clarity Centrate: By maintaining high clarity in the liquid phase separated from the sludge, the returned pollution load to the plant headworks was reduced, boosting overall treatment efficiency.
Reliable Solution for Public Infrastructure: Operating with high stability and consistency even under massive city-scale wastewater loads, our engineering capability has been proven once again.
