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.

The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms ...
The plant, designed to supply Baku and the Absheron Peninsula with drinking water, was put into operation on 28 October 2015. The capacity of the ultrafiltration (UF) plant is 6.6 cubic meters of water per second (570,000 cubic meters per day). [1] [2] The plant complex was chosen as one of the most important water projects in the world at the ...
This contaminated water can be disposed of, along with the sludge from the sedimentation basin, or it can be recycled by mixing with the raw water entering the plant although this is often considered poor practice since it re-introduces an elevated concentration of bacteria into the raw water. Some water treatment plants employ pressure filters.
A Georgia man was arrested Monday in the 1985 murder of two people at a church, after the original suspect spent two decades in prison.
From 2010 to 2014, he was a lecturer at the University of California, Los Angeles where he taught a course in water treatment plant design. In 2014, he was appointed as adjunct professor at UCLA where he taught courses in the Civil and Environmental Engineering Department and the Institute of Environment and Sustainability.
