Following flocculation, the floc particles are large and heavy enough to settle within the sedimentation basins. The sedimentation basins are equipped with a series of parallel inclined plates to enhance the settling process.
As an innovative technology, the use of inclined plates substantially reduces the basin surface area requirements, accomplishing equivalent solids removal in a much smaller floor area than in a conventional sedimentation process.
In the sedimentation basin, as the flocculated water travels upward between the plates, the heavy floc particles naturally fall by gravity. Once a floc particle lands on a plate surface, it slides down the plate to the bottom of the basin for removal.
From there, the solids are sent to the residual solids processing facility.
