Travelling bridges for sludge removal in wastewater treatment plants
Efficiently removing sludge and scum is crucial in wastewater treatment to ensure optimal water quality and compliance with environmental standards. Travelling bridges streamline this process by automating sludge collection in rectangular settling tanks.

Removes Sludge and Scum from Wastewater
The PVV Travelling Bridge for Sludge Removal from WAMGROUP is an engineered system designed for efficient removal of sludge and scum in both municipal and industrial wastewater settings. Operating on a multi-stage system, it features a movable truck mounted on traction trolleys, with a surface scraper and immersed pumps for precise sludge transfer into an external hopper. Commonly employed in municipal wastewater treatment, pulp and paper processing, and tannery effluent management, it is capable of handling tanks up to 12 meters wide and 50 meters long, ensuring high throughput with continuous, automated operations. The system is constructed with options in hot-dip galvanized carbon steel, 304L or 316L stainless steel, ensuring durability and corrosion resistance for harsh environments. It integrates easily into existing infrastructure due to its adaptable design and provides easy operation via its control panel. The equipment supports energy-efficient operation with alternative voltage and motor protection options, ensuring cost-effective performance and minimal maintenance requirements.
