solidXdrain - Model C -Disc Thickener

A slowly rotating, inclined and perforated disc is covered with screen cloth. Conditioned sludge is evenly distributed over the radius of the disc by a guiding device. The thin sludge accumulates at the low point of the disc, creating a hydrostatic pressure that ensures better drainage of the filtrate. During the upward movement, rotating disturbing bodies gently rearrange the sludge so that a free screening surface is always created for unhindered filtrate discharge. At the discharge, a specially shaped scraper pushes the thickened sludge from the disc into the outlet box. Between discharge and feed, the screen is cleaned by water nozzles.
