The wastewater treatment facility is an extended aeration return activated sludge plant.
As the wastewater is brought to the plant, the wastewater travels through our influent head works system. The larger debris is removed with a coarse bar screen mechanism and the smaller debris is removed with a grit classifier. In the grit classifier the water is spun to make the solids side of the tank and settle out for pumping to disposal, and the water flows to the next process. As the water flows into the aeration basins, return activated sludge is introduced into the flow of wastewater to start the biological treatment process. Return activated sludge is introduced at a specific flow from the clarifier to adequately treat the incoming volume of domestic waste. In the aeration tanks, diffused air is also introduced to provide the biology with an oxygen rich environment to allow the biology to consume waste and reproduce more biological organisms.
After this process is complete, the water flows to the secondary clarifier where the biology settles to the bottom and the treated water flows out of the clarifier back to the river.
The solids that accumulate here are the same ones that are reintroduced to the aeration basins to keep the treatment process going on a continuous basis. While returning sludge to the aeration basins, a calculated percentage of that flow is routed to our drum press and removed from the process and disposed of at the drying bed site.
The Wastewater Treatment Plant is located at 6600 94 St.
