Specially designed for grit chambers in municipal wastewater treatment plants, industrial pre-treatment units, and working conditions with high grit load and fluctuating hydraulic loads.
Application
• Wastewater treatment plants with high influent grit content and large variations in hydraulic load.
• Retrofit projects where traditional non-metallic grit collectors frequently experience chain breakage, scraper misalignment, or grit pit turbulence.
• Grit removal systems requiring reduced manual maintenance and improved grit capture efficiency—especially where grit separators and suction pumps underperform.

Description
• Robust & Stable Operation
Addresses Key Failures of Traditional Systems:
Enhanced with segmented chain tensioning adjustment, coaxial drive shaft, and reinforced support frame. Effectively eliminates frequent failures such as scraper misalignment, chain deformation or breakage, and shear pin ejection. Extends fault-free operating cycles by over 60%.
• Adapted to High Load Variations:
The system’s balanced load distribution prevents chain overload, ensuring continuous and stable grit removal even under flow rates exceeding design capacity.
• Efficient Grit Capture & Reduced Secondary Pollution
Anti-Turbulence Design:Fitted with an impact-resistant steel deflector above the grit pit to block incoming flow and eliminate vortex interference. Prevents resuspension of settled grit and improves grit capture efficiency to over 95%.
Flow-Guided Settling:The tank bottom and grit pit are coated with anti-corrosive lining to reduce friction and guide grit particles toward the scraping path, minimizing sediment accumulation.
• Low Maintenance & Easy Operation
Integrated Backwash System:Utilizing the existing aeration vent pipe, dual-nozzle spray arms are added for manual periodic backwashing. Effectively clears grit paths and reduces manual cleaning by 80%. Maintenance can be performed without halting operations.
User-Friendly Adjustment & Inspection:Segmented chain tension allows easy checks and adjustments. Wear on guide rails and clearance is visually detectable, simplifying inspections and preventing extensive damage caused by undetected faults.
• Durable Materials for Long-Term Operation
High-Strength Chain Options:Available in advanced composite or metal-reinforced chains with enhanced aging resistance and 30% higher tensile strength. Withstands uneven lateral stress without deformation. Service life exceeds 8 years (vs. 3–5 years for traditional systems).
Core Structure
• Chain System:
Segmented tightening design with wear-resistant guide rails ensures uniform chain tension and reduces derailment risks. Made of high-strength composite materials for durability.
• Drive System:
Coaxial drive shaft with reinforced brackets ensures horizontal gear alignment, reducing chain wear and breakage.
• Anti-Turbulence Assembly:
Impact-resistant steel plate above the grit pit disperses inflow forces and stabilizes grit settling.
• Backwash Module:
Leveraging existing aeration pipelines, dual-nozzle spray pipes are installed in the grit pit to support manual backflushing and prevent clogging.
Key Performance Indicators
• Grit Removal Efficiency: ≥95% (for grit particles ≥0.2mm)
• Hydraulic Load Adaptability: Stable operation under up to 1.2× design flow
• Fault-Free Operating Period: ≥180 days (under standard conditions)
• Backwash Pressure: Compatible with aeration system (0.2–0.4 MPa)
• Corrosion Resistance: Contact surfaces coated with anti-corrosive materials; scraper and chains available in 304 stainless steel or reinforced composites; suitable for pH 6–9 wastewater
Safety & Compatibility
• Dual Protection Mechanisms:Equipped with mechanical overload protection and electrical torque limiters to prevent damage from sudden loads.
• System Compatibility:Easily integrates with existing grit chambers and suction piping. Requires minimal civil modifications and allows fast installation (≤7 days).
