UV treatment is rapid and, in terms of primary energy use, approximately 20,000 times more efficient than boiling. [citation needed] UV disinfection is most effective for treating high-clarity, purified reverse osmosis distilled water. Suspended particles are a problem because microorganisms buried within particles are shielded from the UV ...
The Ashbridges Bay Wastewater Treatment Plant is the city of Toronto's main sewage treatment facility, and the second largest such plant in Canada after Montreal's Jean-R. Marcotte facility. [1] One of four plants that service the city of Toronto, it treats the wastewater produced by some 1.4 million of the city's residents and has a rated ...
Ultraviolet light (UV) is very effective at inactivating cysts, in low turbidity water. UV light's disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids. The main disadvantage to the use of UV radiation is that, like ozone treatment, it leaves no ...
The UV facility treats water delivered by two of the city's aqueduct systems, the Catskill Aqueduct and the Delaware Aqueduct, via the Kensico Reservoir. [3] (The city's third supply system, the New Croton Aqueduct, has a separate treatment plant. [4]) The plant has 56 energy-efficient UV reactors, and cost the city $1.6 billion.
In real-world applications of wastewater treatment, however, this term usually refers more specifically to a subset of such chemical processes that employ ozone (O 3), hydrogen peroxide (H 2 O 2) and UV light [2] or a combination of the few processes. [3]
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.
