Abstract

An enclosed filter having one or more vertical filter elements (20), on to the outer surfaces of which particulates are deposited, has a moveable floating scraper (26) which surrounds each element, and a system for lowering and raising the liquid level in a housing. The scraper assembly may be constructed of aluminum, wood, polystyrene foam, or PVC and may include a hollow float, so that the apparent density of the scraper is lower than the process liquid. The holes in the scraper, through which pass the filter elements, are preferably formed with sharp edges to assist removal of the solids from the surfaces.
