Client Background
A major municipal sludge treatment project in Indonesia, tasked with processing urban wastewater sludge to reduce environmental impact, required reliable conveying equipment tailored to high-moisture, clog-prone material conditions.
Challenges
1.High-moisture sludge caused frequent clogging in traditional shafted conveyors, leading to unplanned downtime;
2.Corrosive sludge environments shortened equipment service life, increasing long-term maintenance costs;
3.Energy inefficiencies of existing systems raised operational expenses for the large-scale treatment facility.
Solution
We delivered 18 tailor-designed shaftless screw conveyors with industry-specific enhancements:
·Corrosion-resistant coating: Formulated for high-moisture sludge environments to extend equipment lifespan;
·Anti-clog spiral design: Customized geometry eliminates material buildup (the core issue with shafted models);
·Energy-efficient drives: Reduces power consumption by up to 30% for cost savings;
·Easy-access maintenance points: Minimizes downtime for inspections and repairs.
To ensure seamless integration, our team conducted targeted material testing (matching Indonesian sludge characteristics) and provided VR training for local operators.
Project Outcomes
1.Operational Reliability: Zero clog-related downtime reported post-commissioning;
2.Cost Efficiency: 30% lower energy costs + reduced maintenance frequency (thanks to corrosion-resistant design);
3.Environmental Impact: The conveyors support the facility’s ability to process urban wastewater sludge, cutting local pollution from untreated waste.
