| Microsand particles and polymer are added to the floc in the same tank. |
| Because of the difficulties of moving the floc, emptying the tanks could take up to six months. |
| The formation of a white floc or the appearance of a pink colour are indicative of the presence of moisture or deterioration of the reagent. |
| The incoming water flocculates in the lower section of the tank and passes upwards through the floc blanket. |
| When depectinization is complete, a floc is typically formed by the aggregation of partially degraded pectin-protein aggregates. |
| These include the membrane bioreactor process, the ballasted floc reactor, and the integrated fixed-film activated sludge process. |
