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.
