| These include the membrane bioreactor process, the ballasted floc reactor, and the integrated fixed-film activated sludge process. |
| The efficiency of floc particles settling in horizontal liquid flow depends on the area available for settling. |
| When depectinization is complete, a floc is typically formed by the aggregation of partially degraded pectin-protein aggregates. |
| Then the system injects ultrafine sand that binds to floc and drags it to the bottom of a tube-lined tank. |
| In a ballasted floc reactor, the settling rate of suspended solids is increased by using sand and a polymer to help coagulate the suspended solids and form larger masses called flocs. |
| An original patented floor facilitates the coalescence of air bubbles and floc. The latter is drained off by overflowing into troughs. |
