Primary Plant Description
The wastewater flows from the preliminary treatment grit chambers to the primary treatment process which removes Settleable and floatable materials from the wastewater. This occurs in the primary clarifiers which provide a quiescent zone for the sludge to settle and be collected into hoppers by a traveling flight and chain system. Primary sludge is pumped out of the clarifier and on to the Solids Handling process.
Baffles were installed in the clarifiers to increase removal efficiencies.

Primary Clarifiers
Grease and other floatable material is skimmed from the surface and collected during the primary clarification process. The grease that is collected from the primary clarifiers is concentrated, then feed into the incinerators.
The wastewater flows on to Secondary Treament for further pollutant removal.
