| There are two (2) secondary clarifiers. Each clarifier is forty eight (48) feet in diameter with a side water depth of ten (10) feet. | |
| The secondary clarifiers remove suspended solids and scum present in the effluent from the rotating biological contactor units. The removal of the settleable solids is accomplished by allowing the wastewater to move through the clarifiers at such a reduced velocity that the larger particles settle out. The floatable solids (scum) that rise to the surface are removed by skimmers that scrape this material to the scum box. |
