Waters exiting the flocculation basin might enter the sedimentation basin, also referred to as a clarifier or settling basin. This is a big tank with minimal water velocities, allowing for floc to settle to The underside. The sedimentation basin is very best Positioned near the flocculation basin And so the transit in between the two procedures does not permit settlement or floc split up.
