| Palygorskite and sepiolite clays also are used because of their resistance to flocculation under high salinity conditions. |
| They are based on the precipitation, or flocculation, that takes place when antibody and specially prepared antigens are mixed together. |
| The flocculation tank has wooden paddle-type mixers that slowly rotate on a horizontal motor-driven shaft. |
| The dredged mud-water mixture was cleaned in a flocculation treatment barge and an active carbon filtration system. |
| The presence of fats and oils in the seeds prevents flocculation, and the beer cannot keep its froth. |
| Direct filtration process consists of chemical coagulation, rapid mixing and flocculation followed by rapid sand filtration. |
