Fact Sheet: Centrifuge Thickening and Dewatering US EPA

2021-8-18  Centrifugal thickening and dewatering of sewage sludge is a high speed process that uses the force from rapid rotation of a cylindrical bowl to separate wastewater solids from liquid to produce a non-liquid material referred to as “cake.”

2019-3-29  Sludge thickening normally refers to the process of reducing the free water content of sludges; whereas, dewatering refers to the reduction of floc-bound and capillary water content of sludges. See Tables 17-1 and 17-2 for typical performance expectations for various thickening and dewatering processes, respectively.

Thickening Sludge Processing

Thickening processes concentrate the sludge by removing part of the free water, i.e. the water not associated with the sludge particles or flocs. The finished product retains the liquid, free-flowing characteristics of the feed, and can therefore be pumped

What is the Sludge Thickening Process in Water Treatment

2018-3-6  Sludge thickening is important because it is the process used in wastewater treatment centers to increase the solids concentration and decrease the free water. This step minimizes the load on the downstream processes, such as sludge dewatering and digestion.

Alfa Laval Sludge treatment, dewatering and thickening

2021-8-21  On-site sludge thickening and sludge dewatering is a fundamental part of all current wastewater treatment processes to reduce sludge volume, waste disposal cost and meet sustainability requirements. It is also highly relevant for sludge to be used as digester feed for biogas production, thermal processes and composting.

🚧 Dewatering Sludge Processing

Dewatering processes mechanically remove a significant proportion of the sludge water content to produce a "cake" product, with a dry solids concentration of 15-45%. At this concentration the concentrated product can only be transported by conveyor belt.

Sludge Thickening an overview ScienceDirect Topics

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].
