ตัวกรองผลการค้นหา
Fluidization
แปลว่า(Environmental Engineering) The suspension of particles by sufficient upward velocity of the fluid. During fluidization the gravity force is overcome by a combination of buoyancy and fluid friction.
CFCs
แปลว่า(Environmental Engineering) Chlorofluorocarbons, chemicals which result in a depletion of the ozone layer in the upper atmosphere.
Closure
แปลว่า(Environmental Engineering) The act of preparing a landfill for long term inactivity, including placement of a cover over the landfill to prevent infiltration of surface water.
Anaerobic process
แปลว่า(Environmental Engineering) A process which only occurs in the absence of molecular oxygen.
Source reduction
แปลว่า(Environmental Engineering) The elimination or reduction of the waste at the source by modification of the actual process which produces the waste.
System
แปลว่า(Environmental Engineering) An arbitrarily defined area or volume surrounded by a boundary and possessing specific inputs, outputs, and reactions.
Hindered (Zone) settling
แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficient that particles interfere with the settling of other particles. Particles settle together as a body or structure with the water required to traverse the particle interstices.
Anoxic process
แปลว่า(Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.
Ligand
แปลว่า(Environmental Engineering) The ion or molecule which surrounds or complexes with the central atom or ion.
Irreversible reaction
แปลว่า(Environmental Engineering) A reaction in which the reactant(s) proceed to product(s), but the products react at an appreciable rate to reform reactant(s).
Species
แปลว่า(Environmental Engineering) In chemistry, an ion or molecule in solution.
Maximum contaminant level (MCL)
แปลว่า(Environmental Engineering) The maximum allowable concentration of a given constituent in potable water.
