Rotating Bridge Scrapers
The
rotating half bridge scraper is designed to remove settled sludge and scum from
circular settlement tanks.
The equipment in a tank comprises a galvanised fabricated bridge structure of
Channel or Universal Beam sections complete with a galvanised steel open mesh
flooring walkway suitable handrails and toe plates.
The half bridge scraper rotates about a central pivot and its outer end is
fitted with an end carriage which carries the bridge drive and wheel assemblies.
A series of trailing scrapers remove the settled sludge from the tank floor. The
scrapers are arranged to form a continuous volute (spiral) or chevron pattern to
ensure that sludge is directed towards a central hopper in the tank floor.
Designed in accordance with the site specific requirements, George Green also
adhere to the latest W.I.M.E.S 2.03 specification.
