The flocculated water enters a settling tank where the particles settle to the bottom and a circular scraper rakes them into a sump in the center of the basin. From the sump, the material goes into hydrocyclones, which separate the sand from the solids or sludge. The sand recycles to the injection tank and the solids flow by gravity to lagoons.
