  • Sludge Thickening an overview ScienceDirect Topics

    Sludge is introduced at a central feed well and the supernatant overflows a peripheral weir. The sludge is thickened by the action of a specially designed rake which also moves the thickened sludge to a central hopper, of included angle 60°, for intermittent discharge under hydrostatic head (Albertson, 1992).

  • What is the Sludge Thickening Process in Water

    2018-3-6 · Gravity thickening involves using specially designed circular tanks that concentrate thin sludges to a more-dense sludge product. The limitation of this form of clarification water treatment is that it works mostly for the excess watery sludge derived from an activated-sludge process. Thickening tanks have slow-moving vertical paddles.

  • Gravity Thickening SpringerLink

    Sludges are thickened primarily to decrease the capital and operating costs of subsequent sludge processing steps by substantially reducing the volume. Thickening from 1 to 2% solids concentration, for example, halves the sludge volume. Further concentration to 5% solids, reduces the volume to one-fifth of its original volume.

  • Biosolids Technology Fact Sheet Gravity Thickening

    Gravity thickening reduces the downstream requirements for further sludge processing, and thus it is often used prior to anaerobic digestion or lime stabilization. Historically, thickening was not employed prior to aerobic digestion because it was difficult to supply enough oxygen to the digestion process when the total solids content was

  • Gravity Thickening SpringerLink

    Thickening is defined as removal of water from sludge to achieve a reduction in moisture content of slurries. The resulting material is still fluid. Thickening is used at most wastewater treatment plants, as an economic measure, to reduce the volume of sludge or for greater efficiency in subsequent processes.

  • Sludge Thickening Degremont®

    Extremely dilute sludge delivered by the water line (usually 99 to 99.8% water)is concentrated to produce sludge containing 90 to 96% water. This sludge is still fluid and, therefore, can be pumped out. Thickening constitutes an additional investment cost and a source of possible nuisances.
