OVIVO® Thickener

The Ovivo® thickener mechanism uses the fundamental principal of gravity separation of solids from liquid to produce a clarified overflow water and sludge. The sludge or minerals enter the thickener though the column or a side influent pipe and then into the feedwell.

Thickening is defined as removal of water from sludge to achieve a reduction in moisture content of slurries. The resulting material is still fluid. Thickening is used at most wastewater treatment plants, as an economic measure, to reduce the volume of sludge or for greater efficiency in subsequent processes.

Sludge Dewatering: The operators store sludge in the gravity thickener tanks until they are ready dewater the sludge. The sludge settled out in the conical bottom of the thickeners and the supernatant is drained off and discharged back to Lake Norman. Currently, the operators control the supernatant removal manually.
