  • What is the Sludge Thickening Process in Water Treatment

    Mar 06, 2018· Sludge contains biosolids that have been removed from liquid sewage. Sludge thickening is the process used in wastewater treatment centers to increase the solids concentration and decrease free water. This step minimizes the load on sludge dewatering and digestion.

  • Sludge Thickening an overview ScienceDirect Topics

    Sludge Thickening. Sludge thickening is a process in which the solids concentration is increased and the total sludge volume is correspondingly decreased, but the sludge still behaves like a liquid instead of a solid. Thickening commonly produces sludge solids concentrations in the 3% to 5% range, whereas the point at which sludge begins to

  • Wastewater treatment Sludge treatment and disposal

    Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume.
