  • Thickening | Sludge Processing

    Thickening. Thickening processes are those which concentrate the sludge by removing part of the free water, i.e. the water not associated with the sludge particles or flocs. In doing so, the finished product retains the liquid, free-flowing characteristics of the feed sludge, so that it can still be conveyed by pumping.

    Over 80% of plants in China use a combination of thickening, conditioning and dewatering [7]. Gravity thickening is a process in which solids are left to settle in a tank under the influence of gravity. It is widely used in China [7,51] and tends to be the least energy-intensive method of thickening sludge [51].
