for sludge treatment


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. Venturi mixer Upstream in the process, the Venturi mixer ensures efficient inline flocculation, without additional power consumption. Small footprint Low energy consumption Easy to install Lower polymer consumption Operator-friendly design Specific inlet and outlets hatches for process control (flocculation and infeed/outlet dryness) Sampling point with manual valve for filtrate quality control Sampling point (with manual half-pipe sampling collector) for thickened sludge checks Specific washing ramp rotary handle with specific hatches (for quick access and operator control without stopping the machine). A safety switch stops the water supply when required Specific automatic flushing point for tank cleaning (avoiding manual maintenance, process issues, and clogging) Hatches on the main cover allow quick and easy access to perform drum washing or periodical checks
