Nitrification

แปลว่า(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.

Limnology

แปลว่า(Environmental Engineering) The study of freshwater ecosystems.

Phenyl

แปลว่า(Environmental Engineering) A benzene ring named as a constituent group, C6H5-.

Discrete settling

แปลว่า(Environmental Engineering) Settling in which individual particles settle independently, neither agglomerating or interfering with the settling of the other particles present. This occurs in waters with a low concentration of particles.

Autotrophs

แปลว่า(Environmental Engineering) A group of organisms capable of obtaining carbon for synthesis from inorganic carbon sources such as carbon dioxide and its dissolved species (the carbonates). This group includes plants and algae.

System

แปลว่า(Environmental Engineering) An arbitrarily defined area or volume surrounded by a boundary and possessing specific inputs, outputs, and reactions.

Ligand

แปลว่า(Environmental Engineering) The ion or molecule which surrounds or complexes with the central atom or ion.

Maximum contaminant level (MCL)

แปลว่า(Environmental Engineering) The maximum allowable concentration of a given constituent in potable water.

Thiols

แปลว่า(Environmental Engineering) Organic compounds which contain the "-SH" functional group. Also called mercaptans.

Compound

แปลว่า(Environmental Engineering) A substance composed of two or more elements.

HAPs
