Water industry. Flocculation and settling stage for purifying drinking water at a waterworks. These circular basins use flow control technology to promote flocculation (where small particles clump together and float to the surface) and settling (where sediment and other fine particles settle out of solution). The purified water is then passed on to the next stage of the process. These clarifier units use Cyclofloc technology. Photographed at a waterworks operated by SMAT, the metropolitan water company of Turin, Italy.
