Effluent Guidelines (also referred to as Effluent Limitation Guidelines (ELGs)) are U.S. national standards for wastewater discharges to surface waters and publicly owned treatment works (POTW) (also called municipal sewage treatment plants). The United States Environmental Protection Agency (EPA) issues Effluent Guideline regulations for ...
Poole–Frenkel effect. In solid-state physics, the Poole–Frenkel effect (also known as Frenkel–Poole emission[1]) is a model describing the mechanism of trap-assisted electron transport in an electrical insulator. It is named after Yakov Frenkel, who published on it in 1938, [2] extending the theory previously developed by H. H. Poole.
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
An effluent limitation is a United States Clean Water Act standard of performance reflecting a specified level of discharge reduction achievable by the best available technology or related standards for various sources of water pollution. [1] [2] These sources include all industries, businesses, municipal sewage treatment plants and storm sewer ...
Effluent is defined by the United States Environmental Protection Agency (EPA) as "wastewater–treated or untreated–that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters". [1] The Compact Oxford English Dictionary defines effluent as "liquid waste or sewage discharged ...
Insulator assembly with housing and high voltage bus removed for maintenance and inspection. Insulators are typically used to hold up the electrode fields between the grounded collection plates. An electrostatic precipitator (ESP) is a filterless device that removes fine particles, such as dust and smoke, from a flowing gas using the force of ...
Continuous emission monitoring systems (CEMS) are used as a tool to monitor the effluent gas streams resulting from combustion in industrial processes. CEMS can measure flue gas for oxygen, carbon monoxide and carbon dioxide to provide information for combustion control in industrial settings. [1][2] They are also used as a means to comply with ...
