(Environmental Engineering) Influent wastewater entering the plant which has an unusually high organic content and/or high flow rate.
(Environmental Engineering) A municipal or domestic wastewater treatment facility.
(Environmental Engineering) Consumed or used water from a municipality or industry that contains dissolved and/or suspended matter.
(Environmental Engineering) or Publicly Owned Treatment Works Any municipally owned wastewater treatment facility.
(Environmental Engineering) The removal of any dissolved or suspended contaminants beyond secondary treatment, often this is the removal of the nutrients nitrogen and/or phosphorus.
(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.
(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.
(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.
(Environmental Engineering) A water which receives wastewater (treated or otherwise) discharges.
(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.
