ตัวกรองผลการค้นหา
Receiving water
แปลว่า(Environmental Engineering) A water which receives wastewater (treated or otherwise) discharges.
Metabolism
แปลว่า(Environmental Engineering) The processes which sustain an organism, including energy production, synthesis of proteins for repair and replication.
Nitrogenous oxygen demand (NOD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any ammonia present in a water.
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.
Limnology
แปลว่า(Environmental Engineering) The study of freshwater ecosystems.
Phototroph
แปลว่า(Environmental Engineering) Organisms which obtain energy from light using photooxidation.
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.
Runoff
แปลว่า(Environmental Engineering) The water that flows overland to lakes or streams during and shortly after a precipitation event.
Secondary treatment
แปลว่า(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.
Phenyl
แปลว่า(Environmental Engineering) A benzene ring named as a constituent group, C6H5-.
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.
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.
