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, the design also adheres to the latest W.I.M.E.S 2.03 specification.
NCTS Ltd. are pleased to have carried out the design for several of these projects for our client, George Green (Keighley) Ltd.
