Travelling bridges for grease and grit removal in wastewater treatment
Ensure efficient grease and grit removal in wastewater treatment with travelling bridges, designed to optimize separation and streamline maintenance while enhancing overall process reliability.

Removes Grease and Grit from Wastewater
The Travelling Bridges for Grease and Grit Removal PVA, brought to you by WAMGROUP, offer a robust solution for municipal and industrial wastewater treatment facilities. This equipment distinguishes itself by incorporating a movable truck mechanism equipped with a surface scraper and an immersed pump, enabling efficient grease and grit separation. The bridge operates using a centrally driven gearbox, transporting settled grit to collection hoppers and guiding scum into grease channels through a seamless back-and-forth motion. Ideal for applications ranging from pulp and paper processing to tannery waste management, this system ensures the production of clarified water and dewatered sludge. Designed for tanks up to 50 meters long, it features hot dip-galvanized carbon steel or stainless steel construction for enhanced durability. With options for grit suction via air lift and adaptable to existing infrastructure, it supports customization needs while facilitating ease of maintenance.
