Traveling Bridge Grit & Grease Scraper
Reliable Sedimentation & Skimming for Large-Scale Wastewater Plants.
- Item 1:Dual Function: Removes bottom grit and surface grease/scum simultaneously.
- Item 2: Wide Span: Custom bridge spans up to 20 meters for massive channels.
- Item 3: Automation: Fully automated reciprocating travel with PLC control.
In large longitudinal tanks, grit accumulation can become uneven, and surface scum (grease/oil) creates odor issues. Traditional chain-driven scrapers are prone to mechanical jamming, corrosion, and high maintenance costs due to underwater moving parts.
Our Traveling Bridge Scraper moves along rails above the water, keeping drive components dry and accessible. It uses submersible pumps or scrapers to remove bottom grit while a surface skimmer removes grease. The result is reliable, dual-action cleaning with minimal maintenance requirements.

Q1: Pump suction or scraper blade? Which is better?
A: Pump suction is ideal for deeper tanks and fine grit removal as it vacuums the floor. Scraper blades are robust and better suited for heavy, coarse grit loads. Feiran EP offers both options based on your site conditions.
Q2: Can it handle multiple channels?
A: Yes. We can design a single wide bridge that spans across multiple parallel channels, synchronizing the cleaning process and reducing equipment costs.
Q3: Is the rail system included?
A: Yes, we provide the complete package including precision-machined rails, power supply cables (festoon or reel), and limit switches for safety.
