Primary Clarifiers

There 2 primary clarifiers. Each clarifier 40 feet in diameter with a side water depth 7 feet.

The primary clarifiers remove settleable solids, scum, and a portion of the BOD from the wastewater, preparing it for further treatment 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.
