  Sludge conditioning, thickening and dewatering …

  2021215 · High centrifugal forces generated from up to 1500 G gravity acceleration separate solid particles from the sludge, generating a liquid-rich stream and a solids-rich stream at the exit of the CFDC. A single pass of phosphoric-acid sludge through the CFDC yielded 95 % liquid recovery and 90 % recovery of REEs-containing solids from 20 to 34 …

  Solid – Liquid Separation – Thickening - ScienceDirect

  201611 · The thickener operation can be a batch or continuous process, with either co-current or counter-current flow of underflow and overflow slurries. The filtering operation may also be batch or continuous. For rapid solid–liquid separations, centrifugal forces are used and equipment similar to those described under classification are employed.

  Lesson 23: Sludge Dewatering and Thickening

  2021625 · thickener designs usually include circular tanks, 3-4 m (10-13 ft) deep and up to 25 m (82 ft) in diameter. The dimensions are based on prediction of settling due to gravity alone. To assist solids transport, gravity thickener bottoms are constructed with a floor slope between 1:6 and 1:3. Rectangular units have been used as gravity thickeners.

  Static thickener - Degremont®

  Classic mechanized thickener diameters range from 7 to 30 m. Concrete structure floors have a slope of approximately 15%; however this figure may be exceeded when heavy hydrophobic sludge is involved. A centrally driven, twin diametric arm scraper is used.Appropriate drive torques are applied:60-80 m.daN · m –2 for dense mineral sludge …

  Biosolids, Sewage Sludge, Sludge Thickener - Langley Separation and Process

  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 ...
