Lesson 11: Sludge Thickening Objective - Mountain Empire
Centrifuges are commonly used for thickening waste activated sludge (WAS). Primary sludge is normally not fed to a centrifuge since it may contain abrasive material. In addition to being effective in thickening, centrifuges have the advantage of less space requirement, less odor potential and housekeeping requirement.

Understanding Decanter Centrifuge: A Complete Guide
Sludge thickening using a decanter centrifuge before a digestion treatment process will reduce the size of the digester, and can be used before sludge storage and liquid land applications. Depending on the utilization of the sludge product (landfilled, land applied or dried) the drier the product the more cost effective it will be for storage, transportation and disposal.
