    Jun 18, 2020 A rotary drum thickener (RDT) is based on the same principle as a gravity belt thickener (GBT), in that water drains from the sludge through a retaining porous medium. For an RDT the porous medium is the cylindrical wall of a 0.5−1.5 m diameter drum which rotates at speeds between 5 and 20 RPM while the sludge continually passes through it

    Sludge, a by-product of the wastewater treatment process, must be economically processed for disposal or beneficial reuse. This is a multi-step process. Both primary and secondary sludges are mostly water (often in the 0.5 – 2% solids range) and the first step in the further treatment of sludge is removal of water. Rotary drum thickeners have become the popular choice because they have a
