Anammox bacteria can be found in wastewater treatment plants, lakes, suboxic zones, and coastal sediments. [3] Anammox bacteria are temperature-dependent, requiring temperatures between 30˚C to 40˚C [4] to grow. Anammox bacteria growth is also impacted by pH, growing best at pH ranges of 6.5 to 8.3. [5] Anammox bacteria are made up of an ...
This page consists of a list of wastewater treatment technologies : Activated sludge model. Activated sludge systems. Adsorption/Bio-oxidation process. Advanced oxidation process. Aerated lagoon. Aerobic granular reactor. Aerobic granular sludge technology. Aerobic granulation.
Upflow anaerobic sludge blanket ( UASB) technology, normally referred to as UASB reactor, is a form of anaerobic digester that is used for wastewater treatment . The UASB reactor is a methanogenic (methane-producing) digester that evolved from the anaerobic clarigester. A similar but variant technology to UASB is the expanded granular sludge ...
Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C., is the largest advanced wastewater treatment plant in the world. [1] The facility is operated by the District of Columbia Water and Sewer Authority (DC Water). The plant opened in 1937 as a primary treatment facility, and advanced treatment capacity was added in the 1970s and ...
Wastewater treatment plants in California face a number of challenges, the Water Education Foundation notes, including aging infrastructure; contamination from improperly disposed pharmaceuticals ...
A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes ...
The Nereda technology is an invention of the Delft University of Technology and Engineering consultancy Royal HaskoningDHV. The Nereda derives from the Greek word “Neraida”. Nereda was a water nymph and one of the daughters of Nereus, the wise and benevolent Greek god of the sea. In Greek mythology Nereda is linked with the terms “pure ...
The largest wastewater treatment plants can be defined in several ways. The largest in term of capacity, both during dry and wet-weathers, is the Jean-R.-Marcotte Wastewater Treatment Plant in Montreal. With full secondary treatment of effluents it would be the Deer Island Waste Water Treatment Plant of Boston.
