Wastewater Treatment
The influent to the Wastewater Treatment Facility begins by entering the influent channel at the plant and passes through a gate then into our screen where we remove most debris and solids. The wastewater flows into a wet well where the raw pumps lift the water up and direct it to our Grit Collection system. The wastewater stream is then directed to our oxidation ditches for secondary bio treatment. The ditches provide an extended air secondary treatment for the biosolids. From the ditches the wastewater flows to our clarifiers for settling out the heavier biosolids and separating the clear water. From the clarifiers the clear water goes to our Chlorine contact tank or to the filters. Also from the clarifiers we have a return line and a wasting line. The return line goes to the splitter box in front of the oxidation ditches. This flow helps maintain the bug types and population numbers needed to reduce the solids from the influent stream. The waste line goes to our digesters. The digesters are aerobic tanks that further break down the solids. We pull soup off these tanks, which further increases the solids and separates the clear water. Digesters are filled equally to maintain consistency of air feed to the tanks. From the digesters, sludge is moved to sludge storage. From the Chlorine contact tank it flows into the old chlorine tank where more chlorine can be added as well as SO2 and O2 before it is released to the stream. The Wet well at the front of the plant has two storm pumps used to pump to the equalization tank during high flows. We add air to remove most of the grit and we also remove the floatables before it over flows into the chlorine contact tank and it flows out the same outfall 001 as the fully treated effluent. All effluent sampling incorporates the combined flow to determine treatment effluent quality.
