Sludge Treatment Thickening

Flotation thickening is used most efficiently for waste sludges from suspended growth biological treatment processes such as the activated sludge process or the suspended growth nitrification process.Other sludge such as primary sludge , trickling filter humus, aerobically digested sludge, and sludges containing metal salts from chemical.

  • Sludge Thichening Sewage Treatment Reverse

    Wastewater treatment plants commonly use thickening devices to increase the solids concentration at the end of a particular process step within the activated sludge process.Thickening of sludge increases its solids content and reduces the volume of free water thereby minimizing the unit load on downstream processes such as digestion and dewatering.The most commonly used thickening processes.
