A tornado is a violently rotating column of air in contact with the surface and a cumuliform cloud base. Tornado formation is caused by the stretching and aggregating/merging of environmental and/or storm-induced vorticity that tightens into an intense vortex. There are various ways this may come about and thus various forms and sub-forms of ...
Sewage treatment plant (a type of wastewater treatment plant) in La Crosse, Wisconsin. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
Any tornado that occurs over water is classified as a waterspout, and when one moves over land, it is designated as a tornado. A cargo ship sails near the path of a waterspout near the beach in ...
Not all tornadoes are easily seen. A tornado funnel can be transparent until reaching an area with loose dirt and debris. [2] Also, some tornadoes have been seen against sunlit areas, but rain or nearby low-hanging clouds has obscured other tornadoes. Occasionally, tornadoes have developed so suddenly that little, if any, advance warning was ...
Approved Amendment #2 to the PY 2020 Residential Public Infrastructure Grant to extend the grant end date for the Cinnamon Lake wastewater treatment plant due to continued supply chain issues.
Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
These tornadoes may form at different times or exist simultaneously but are separate from one another. A phenomenon similar to multiple vortices is the satellite tornado. Unlike the multiple-vortex tornado, where smaller vortices form inside the main tornado, a satellite tornado develops outside the main tornado's circulation.
