How It Works
Stircor’s equipment package delivers a complete, integrated drying system engineered to meet stringent performance, safety, and environmental standards.
Precision Biosolids Feed System
The process begins with a controlled feed system that meters 10–15 tons per hour of biosolids at 75–80% moisture, ensuring consistent dryer loading and optimal residence time.
- Maintains steady-state throughput
- Prevents surges that disrupt thermal balance
- Ensures predictable process performance
Direct-Fired, Parallel Flow Dryer
The heart of the system is a direct-fired, parallel-flow dryer — a design known for the best heat-transfer efficiency of any biosolids drying configuration.
- Biosolids and hot gases move in the same direction
- Stable thermal gradients minimize material scorching
- Achieves Class A dryness in a single pass
Venturi Scrubbing System for Emissions & Odor Control
Exhaust air passes through a Venturi scrubber engineered to meet the most stringent particulate standards.
- Efficient particulate removal
- Integrated odor elimination capability
- Supports compliance with local air-quality requirements
Dried Material Discharge & Optional Cooling
Dried material exits through a controlled discharge system that produces granular, uniform biosolids suitable for handling, storage, transport, or beneficial use.
- Granular texture reduces bridging, clumping, and moisture rebound
- Optional cooling prevents auto-ignition and increases operator safety
Optional Thermal Oxidizer
Facilities requiring additional VOC destruction can integrate a thermal oxidizer prior to exhaust discharge.
- Ideal when upstream digestion does not sufficiently reduce volatiles
- Ensures compliance with advanced emissions standards
Centralized PLC Control & Monitoring
All equipment systems — feed, dryer, air handling, discharge — are operated through a single control center.
- Real-time temperature, airflow, and feed monitoring
- Automated interlocks for complete system safety
- Comprehensive data recording for operational transparency
Dried Biosolids Loadout
The system includes a loadout configuration designed for truck or roll-off filling, providing a clean, efficient transfer of dried material for agricultural, landscaping, or disposal pathways.
