  "term": "Aeration",
  "field": "Environment",
  "definition": "1. The act of mixing a liquid with air (oxygen).\n\n2. A process which promotes biological degradation of organic matter in water. The process may be passive (as when waste is exposed to air), or active (as when a mixing or bubbling device introduces the air).\n\n3. (air-A-shun) The process of adding air to water. Air can be added to water by either passing air through water or passing water through air.\n\n4. A process that promotes biological degradation of organic matter in water. The process may be passive (as when waste is exposed to air) or active (as when a mixing or bubbling device introduces the air).\n\n5. Process that promotes biological degradation of organic matter in water. The process may be passive (as when waste is exposed to air) or active (as when a mixing or bubbling device introduces the air).\n\n6. The process of bringing air into contact with a liquid (typically water), usually by bubbling air through the liquid, spraying the liquid into the air, allowing the liquid to cascade down a waterfall, or by mechanical agitation. Aeration serves to (1) strip dissolved gases from solution, and/or (2) oxygenate the liquid. The rate at which a gas transfers into solution can be described by Fick's first law.\n\n7. Providing contact with air or pure oxygen to increase dissolved oxygen (DO) in wastewater.",
