GRAVITY THICKENING OF ACTIVATED SLUDGE

2016-8-9  gravity thickening. Gravity thickening of sludge is defined as a process by which particles, or aggregates of particles of dilute sludge, due to their greater specific gravity, settle through water and concentrate. Besides reducing subsequent chemical and volumetric require-ments in dewatering processes, gravity thickening is also an

Biosolids Technology Fact Sheet - EPA

2018-11-19  Gravity Thickening DESCRIPTION Thickening is the process by which biosolids are condensed to produce a concentrated solids product and a relatively solids-free supernatant. Thickening wastewater solids reduces the volume of residuals, improves operation, and reduces costs for subsequent storage, proce ssing, transfer, end use, or disposal.
