Scraper Bridge

Sludge settling

Equipment designed for primary and secondary settling tanks in urban or industrial wastewater treatment plants that contain solids which can settle quickly, and can then be extracted for sludge processing.
Scraper bridge made entirely of aluminium or stainless steel for extremely long durability (compared to galvanised steel solutions in particular).
Robust and reliable solution.
The Scraper bridge is designed to be installed in circular settling tanks.
Several hundred scraper bridges installed over the last 60 years.

Components
1
Aluminium walkway and guardrail
2
Aluminium structural beam
3
Stainless steel weir blade for clarified water discharge
4
Stainless steel skimming blade - to capture floating matter
5
Stainless steel surface scraper to direct scum and other floatable particles to the discharge hopper
6
Stainless steel hopper for the discharge of scum and other floating materials
7
Geared motor and drive, allowing the rotation of the whole bridge, located at the end of the construction located within a frame which also serves as a support
8
Non-driving support wheel ensuring the stability of the bridge when rotating
9
Ring collector for the power supply of the bridge components
10
Hinged central pivot
11
Stainless steel feed-well to distribute the effluent inlet flow
12
Stainless steel and EPDM tank scrapers – moves the sludge to a central collector where it is discharged by gravity
