Chemical oxygen demand (COD)

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

Oxidative phosphorylation

แปลว่า(Environmental Engineering) The synthesis of the energy storage compound adenosine triphosphate (ATP) from adenosine diphosphate (ADP) using a chemical substrate and molecular oxygen.

Dissolved oxygen (DO)

แปลว่า(Environmental Engineering) The amount of molecular oxygen dissolved in water.

deoxidised copper

แปลว่าทองแดงที่ขจัดอ๊อกซิเจ็นด้วยการเติม deoxidiser เสร็จสิ้นแล้ว

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.

Carbonaceous biochemical oxygen demand (CBOD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any carbon containing matter present in a water.

Box Annealing

แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

Nitrogenous oxygen demand (NOD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any ammonia present in a water.

Toxicity

แปลว่า(Environmental Engineering) A U.S. EPA hazardous waste characteristic defined with a rigorous test procedure, the TCLP (for Toxicity Characteristic Leaching Procedure). In the procedure, a waste is extracted for 24 hours with an acetic acid solution. The acid extract is then analyzed for the presence of any of the contaminants listed in the procedure.

Biochemical oxygen demand (BOD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.

Basic Oxygen Process

แปลว่า(english) (BOP) A process in which molten steel is produced in a furnace by blowing oxygen into molten iron, scrap and flux materials. The furnace is known as Basic Oxygen Furnace (BOF).

Deoxygenation

แปลว่า(Environmental Engineering) The consumption of oxygen by the different aquatic organisms as they oxidized materials in the aquatic environment.
