Sludge thickener Scraper Sludge scraper blade thickening dewatering for sewage sludge treatment

Sedimentation basins, also called settling tanks or clarifiers, are large tanks in which water is made to flow very slowly in order to promote the sedimentation of particles or flocs. Scrapers which are used in repressing sedimented thick substances that float from the water treatment plant can also be used at several phases of water purification.
YOSUN CENTRAL DRIVE SCRAPER FOR SLUDGE THICKENER consist of arms which are fitted on a centre tube. There are angled scraper blades welded under the arms for bottom scraping. Thedrive unit is located on a fixed bridge, and the gear is directly connected to the centre shaft whose lower part is equipped with a bottom bearing to prevent abrasion caused by friction.Fixed bridge circular scrapers remove settling sludge during operation from the circular sedimentation basin. Those settling materials which cannot sink directly into the collecting hopper are pushed
towards the hopper at centre by means of rotating blades. Clear water is collected in the collection channels. Sludge collected in the hopper is removed from the system through a discharge pipe.
