Among the water and wastewater services of a city, wastewater treatment is usually the most energy intense process. [2]Wastewater treatment plants are designed with the purpose of treating the influent sewage to a set quality before discharging it back into a water body, without real concern for the energy consumption of the treating units of a plant.
Pulsed-power water treatment is the process of using pulsed, electro-magnetic fields into cooling water to control scaling, biological growth, and corrosion. The process does not require the use of chemicals and helps eliminate environmental and health issues associated with the use and life-cycle management of chemicals used to treat water. [ 1 ]
The Washington Suburban Sanitary Commission (WSSC Water) is a bi-county political subdivision of the State of Maryland [2] that provides safe drinking water and wastewater treatment for Montgomery and Prince George's Counties in Maryland except for a few cities in both counties that continue to operate their own water facilities.
In the 50 years the Maryland Energy Administration has existed, being tasked with ensuring a future of green energy has required the state to examine how even underserved communities can benefit.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
Mirant was merged into GenOn Energy in 2010, [4] and GenOn merged into NRG in 2012. [ 5 ] In 1991, the 900-foot (270 m)-long cooling water discharge channel from the power plant, which empties into the Potomac River, became the Dickerson Whitewater Course , a canoe and kayak training facility for the 1992 Olympic Games .
Advancements in water treatment technology have affected all areas of industrial water treatment. Although mechanical filtration, such as reverse osmosis , is widely employed to filter contaminants, other technologies including the use of ozone generators, wastewater evaporation, electrodeionization and bioremediation are also able to address ...
Once this water is inside the boiler or steam generator, the process of adding the latent heat of vaporization begins. The boiler transfers energy to the water by the chemical reaction of burning some type of fuel. The water enters the boiler through a section in the convection pass called the economizer. From the economizer, it passes to the ...
