Material Handling in Challenging Applications
The steep elevation gain required for Sarnia’s application demonstrates the versatility of modern enclosed conveyor technology. Traditional sludge pumping systems often struggle with varying moisture contents and can experience significant wear when pumping over long distances or high elevations. The Pathwinder’s mechanical conveying approach offers several advantages:
Consistent Performance: Chain and flight systems maintain steady material flow regardless of sludge consistency variations between 15-35% solids content.
Reduced Maintenance: Compared to progressive cavity pumps handling similar elevations, enclosed conveyors typically require less frequent maintenance interventions.
Energy Efficiency: Once material is in motion, mechanical conveying requires less energy per ton of material moved compared to pumping systems fighting static head pressure.
Operational Flexibility: The system can stop and start under load without concerns about line plugging or priming losses common with pumping systems.
Integration with Existing Infrastructure
The project drawings reveal careful attention to interfacing with Sarnia’s existing facility infrastructure. Key integration points included:
- Precise discharge positioning to align with downstream equipment
- Structural attachment points designed to distribute loads to existing building elements
- Access routes planned to avoid interference with other facility operations
- Utility connections coordinated with available power and control systems
This level of integration planning contributed significantly to the rapid installation timeline. Contractors could prepare mounting points and utility rough-ins before equipment arrival, eliminating common field conflicts that delay projects.
Long-Term Reliability Through Quality Construction
The specification of 304 stainless steel throughout the system represents a significant investment in long-term reliability. In the corrosive environment of wastewater treatment, material selection directly impacts equipment lifespan. The Conveyor Equipment Manufacturers Association (CEMA) recommends stainless steel construction for applications involving:
- Hydrogen sulfide exposure
- High chloride environments
- Frequent washdown requirements
- Extended design life expectations
The Sarnia system’s comprehensive use of stainless steel – from structural components to hardware – positions it for decades of reliable service with minimal corrosion-related maintenance.
