| Palygorskite and sepiolite clays also are used because of their resistance to flocculation under high salinity conditions. |
| The facility incorporates a chromate removal station, which recovers iron, aluminum and chromium through flocculation. |
| Options for harvesting include centrifugation or chemical flocculation, which pushes all the microalgae together, but there are high costs associated with these processes too. |
| They are based on the precipitation, or flocculation, that takes place when antibody and specially prepared antigens are mixed together. |
| The dredged mud-water mixture was cleaned in a flocculation treatment barge and an active carbon filtration system. |
| In this process particles in the water, including the floc created by flocculation, are allowed to settle out of the water naturally by gravity's pull. |
