Climatology |
(Environmental Engineering) The study of the climate, how the earth's atmosphere performs over long periods of time. |
Closure |
(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. |
Coagulation |
(Environmental Engineering) Particle destabilization to enhance agglomeration. |
Colloids |
(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. |
Complexation |
(Environmental Engineering) The ionic bonding of one or more central ions or molecules by one or more surrounding ions or molecules. |
Composting |
(Environmental Engineering) The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning. |
Compound |
(Environmental Engineering) A substance composed of two or more elements. |
Compression settling |
(Environmental Engineering) Settling which occurs in the lower reaches of clarifiers where particle concentrations are highest. Particles can settle only by compressing the mass of particles below. |
Consumers |
(Environmental Engineering) Organisms which consume protoplasm produced from photosynthesis or consume organisms from higher levels which indirectly consume protoplasm from photosynthesis. |
Conversion |
(Environmental Engineering) The fraction of a species entering a system which is converted to product. |
