Various methods of sludge thickening are discussed including the use of settling basins or tanks, tube settlers and lamella settlers, stirrers, centrifuges, and settling aids. Also presented is a brief discussion of dewatering and the processes to accomplish this, such as lagooning, drying beds, vacuum filters, centrifuges, filter press, freezing and thawing.
