IFT Series Rotary Drum Sludge Thickeners Datasheet

IFT Series of Internally-fed Rotary Drum Sludge Thickeners have cylindrical drums with a progressive series of screen elements that are mounted horizontally on four shaft-mounted wheels and supported in a structural housing.

The smallest openings are used to screen the influent sludge, followed by coarser elements as the sludge thickens. The screening element is either woven mesh or wedgewire. The screens are used to remove free liquids from a variety of sludges, including those with appreciable amounts of microbial particles. Sludge containing 0.5% - 3% solids can be thickened to 5% - 15%, depending on the type of sludge.
