Drum thickeners for sludge thickening With more than 30 years of experience in the development and manufacturing of drum thickeners, ANDRITZ SEPARATION has acquired unmatched expertise in this technology. The PowerDrum (PDR) drum thickener for sludge thickening is considered to be an easy and efficient sludge thickening solution prior to the dewatering process and can deal with biological sludge throughputs ranging from 15 to 180 m3/hr. With its simple design and small footprint, the PowerDrum (PDR) drum thickener for sludge thickening is easy to install and requires little supervision and maintenance. The PowerDrum (PDR) drum thickeners for sludge thickening ensure dynamic thickening by rotating sludge continuously. They are specially designed for pre-digestion treatment (for primary, secondary, or tertiary sludge) or when land liquid spreading is planned. The PowerDrum (PDR) drum thickener for sludge thickening may also be used to lower the hydraulic capacity of the dewatering equipment installed in the downstream process. The sludge is conveyed inside the drum due to the drum inclination, as well as the combined action of the drum’s rotating movement and its internal design. This drum has the special feature of having various filtration stages zone-by-zone along its length, with a polyester cloth to achieve better separation efficiency.
