As part of a general plant upgrade, a centrifuge sludge thickening system was installed to separate liquid from the sludge more effectively, creating a thickened sludge with 6–8% dry solids content. This enabled much more efficient transportation—an average of only one tanker per week is now needed—cutting transport costs significantly.
We offer a complete range of decanter centrifuges for wastewater treatment, sludge thickening and dewatering. From robust i-DW units to state-of-the-art ALDEC G3 VecFlow sludge centrifuge systems. Regardless of your demands or challenges, we have the right machine for you.
Sludge thickening is the concentration of sludge from large volumes of wastewater. This type of separation is not an application for filters or other static media separation technology. A decanter centrifuge is a heavy-duty mechanical separator using high centrifugal force. It is efficient for sludge thickening at an industrial scale.
In general, solid bowl centrifuges have the most widespread use, due to high through- put capacity and applications for sludge thickening or dewatering. Imperforate basket centrifuges are also capable of thickening or dewatering, but have lower throughput capacity. Disc-nozzle centrifuges have limited municipal sludge thickening applications.
• Gravity belt thickeners • Centrifuge thickeners • Rotary drum/screw thickeners • Membrane thickeners • Disc thickeners • Volute thickeners The advantages and disadvantages of thickener types should be considered when selecting equipment. Table 1 gives an overview of the most common mechanical thickening devices

&EFA United States Environmental Protection Agency Office of Water Washington, D.C. EPA 832-F-00-053 September 2000 Biosolids Technology Fact Sheet Centrifuge Thickening and Dewatering DESCRIPTION Centrifugal thickening and dewatering is a high speed process that uses the force from rapid rotation of a cylindrical bowl to separate wastewater solids from liquid (U.S. EPA, 1987).
Centrifugal thickening and dewatering of sewage sludge and biosolids is a process that uses the power of centrifugal force to separate wastewater solids from liquid. Thickening before digestion or dewatering reduces the tankage needed for digestion and storage by removing water. Dewatering removes more water and produces a drier material
