Shock load |
(Environmental Engineering) Influent wastewater entering the plant which has an unusually high organic content and/or high flow rate. |
Site remediation |
(Environmental Engineering) The process of cleaning up a hazardous waste disposal site that has either been abandoned or that those responsible either refuse to cleanup or are financially unable to cleanup. |
Source reduction |
(Environmental Engineering) The elimination or reduction of the waste at the source by modification of the actual process which produces the waste. |
Substrate level phosphorylation |
(Environmental Engineering) The synthesis of the energy storage compound adenosine triphosphate (ATP) from adenosine diphosphate (ADP) using organic substrates without molecular oxygen. |
Surface water |
(Environmental Engineering) Water which is contained in lakes, rivers, and oceans. |
Suspended growth reactor |
(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor. |
Synergism is the act of working together. |
(Environmental Engineering) Two chemicals which are synergistic have a greater effect together than the sum of their individual effects. The effect can be either positive or negative. |
Thermocline |
(Environmental Engineering) The depth at which an inflection point occurs in a lake temperature profile. |
Thiols |
(Environmental Engineering) Organic compounds which contain the "-SH" functional group. Also called mercaptans. |
Total dissolved solids |
(Environmental Engineering) (TDS) is the amount of dissolved matter in the water. |
