An elongated scraper profile is provided, preferably for a dewatering device that serves the purpose of dewatering sludge. The scraper profile features a lip section extending in the direction of the longitudinal extension of the scraper profile, which serves the purpose of scraping sludge components from a screen surface. The scraper profile features a fastening section extending in the direction of the longitudinal extension, which serves the purpose of fixing the scraper profile with the assistance of a retainer assembly. The scraper profile also features an intermediate section connecting the lip section and the fastening section, whereas the intermediate section is flexibly formed in a direction running perpendicular to the longitudinal extension, such that the lip section is moveable in the direction of the fastening section.
