  • GRAVITY THICKENING OF ACTIVATED SLUDGE

    One process that concentrates or thickens sludge is known as 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-

    Gravity Sludge Thickener Rock Water Equipment

    Gravity Sludge Thickeners. The RockWater gravity thickeners are designed to create an improved design application involving sludge thickening. The solids are thickened by gravity, then collected at the bottom of the basin and raked to a collection sump for removal by from the thickener pumps. The effluent water exits over the weir plates and out

    Sludge Thickening an overview ScienceDirect Topics

    Gravity thickening is the most common method used to thicken primary sludge and combined primary and secondary sludge. The presence of secondary solids, particularly WAS, typically results in poor gravity thickener performance in terms of solids capture rate and thickened solids concentrations.

    Sludge Thickening Sewage Treatment Reverse Osmosis

    A gravity thickener is similar to a conventional sedimentation tank in design, but has a more steep floor slope. Tanks range from 6 20 m dia & side water depth (SWD) may vary from 3 4 m. Floor slope is varies from 1:4 to 1:6 depending upon the type of sludge, time required for thickening & storage volume to absorb peak solids load.

    What is the Sludge Thickening Process in Water Treatment
