Wastewater treatment systems

Systems and methods for wastewater treatment. A nitrate source may be dosed to a collection tank, such as a wet well, for downstream control of hydrogen sulfide levels in the wastewater. A source of a strong oxidizer may also be dosed to the wet well. The oxidizer, such as chlorite, may temporarily...

description Systems and methods for wastewater treatment. A nitrate source may be dosed to a collection tank, such as a wet well, for downstream control of hydrogen sulfide levels in the wastewater. A source of a strong oxidizer may also be dosed to the wet well. The oxidizer, such as chlorite, may temporarily interrupt denitrification processes in the wet well to prevent floatation of undesirable constituents therein. The oxidizer dosage may be generally consistent with the nitrate dosage. An ORP sensor may facilitate regulation of dosing. The nitrate and the oxidizer may be present in a single mixture to be dosed to the wet well.
