Organic nitrogen

แปลว่า(Environmental Engineering) Nitrogen contained as amines in organic compounds such as amino acids and proteins.

Fixed suspended solids

แปลว่า(Environmental Engineering) (FSS) is the matter remaining from the suspended solids analysis which will not burn at 550°C. It represents the non-filterable inorganic residue in a sample.

Chemical oxygen demand (COD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.

Biosynthesis

แปลว่า(Environmental Engineering) Catabolism, the production of new cellular materials from other organic or inorganic chemicals.

Ultimate biochemical oxygen demand (BODu)

แปลว่า(Environmental Engineering) The total amount of oxygen required to oxidize any organic matter present in a water, i.e. after an extended period, such as 20 or 30 days.

Aldehyde

แปลว่า(Environmental Engineering) An organic compound with a carbonyl at one end of a hydrocarbon group.

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.

Thiols

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

Anabolism

แปลว่า(Environmental Engineering) Biosynthesis, the production of new cellular materials from other organic or inorganic chemicals.

Heterotrophic

แปลว่า(Environmental Engineering) A group of organisms which obtain carbon for synthesis from other organic matter or proteins.

Producers

แปลว่า(Environmental Engineering) Autotrophic organisms which produce protoplasm using inorganic carbon and energy from the sun.

Organic compound

แปลว่า(Environmental Engineering) Any compound containing carbon except for the carbonates (carbon dioxide, the carbonates and bicarbonates), the cyanides, and cyanates.
