(Environmental Engineering) Influent wastewater entering the plant which has an unusually high organic content and/or high flow rate.
(Environmental Engineering) An organic compound with one or more hydroxyl "-OH" groups.
(Environmental Engineering) A group of organisms that do not require molecular oxygen. These organisms, as well as all known life forms, require oxygen. These organisms obtain their oxygen from inorganic ions such as nitrate or sulfate or from protein.

(Environmental Engineering) An organic compound with a carbonyl at one end of a hydrocarbon group.
(Environmental Engineering) A fossilized organic material present in oil shale and some other sedimentary rocks.
(Environmental Engineering) Organisms which utilize inorganic carbon for synthesis of protoplasm. Ecologists narrow the definition further by requiring that autotrophs obtain their energy from the sun. In microbiologist parlance, this would be a photoautotroph. See photoautotrophic and chemoautotrophic.
(Environmental Engineering) The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning.
