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. The steeper slope reduces the raking problems by ...

GRAVITY THICKENING OF ACTIVATED SLUDGE

Gravity thickening is a process which increases the concentration of solids by gravitational forces. There are basically two types of gravity thickening processes: batch settling and continuous settling. Settling velocities are primarily examined in the process of batch thickening. Columns of various depths and diameters are employed but only lumns of 1.5 - 7 ft. in height have proved ...

Biosolids Technology Fact Sheet Gravity Thickening

Gravity thickeners are usually operated at collector tip speeds between 0.08-0.1 m/s (15 and 20 ft/min). This gentle action is intended to break down any matrix (floes) that might form, while minimizing agitation and resuspension of the solids.
