Nitrogenous oxygen demand (NOD)

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

Flocculant settling

แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficiently high that particle agglomeration occurs. This results in a reduction in the number of particles and an increase in average particle mass. As agglomeration occurs higher settling velocities result.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

Limnology

แปลว่า(Environmental Engineering) The study of freshwater ecosystems.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

Phototroph

แปลว่า(Environmental Engineering) Organisms which obtain energy from light using photooxidation.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

Biofilm

แปลว่า(Environmental Engineering) A film of microorganisms attached to a surface, such as that on a trickling filter, rotating biological contactor, or rocks in natural streams.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

Runoff

แปลว่า(Environmental Engineering) The water that flows overland to lakes or streams during and shortly after a precipitation event.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

 ศัพท์ช่างภาษาอังกฤษ – ไทย

Phenyl

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

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

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.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

Saltwater intrusion

แปลว่า(Environmental Engineering) The gradual replacement of freshwater by saltwater in coastal areas where excessive pumping of groundwater occurs.
 ศัพท์ช่างภาษาอังกฤษ – ไทย

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.
