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” and “immaculate”, a reference to the water quality produced by the new technology.
Wastewater treatment. 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. It is also possible to reuse it.
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 ...
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater ...
The AOP procedure is particularly useful for cleaning biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents, and volatile organic compounds in wastewater. [5] Additionally, AOPs can be used to treat effluent of secondary treated wastewater which is then called tertiary treatment. [6]
Moving bed biofilm reactor. Moving bed biofilm reactor ( MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at Norwegian University of Science and Technology in the late 1980s. [ 1] The process takes place in an aeration tank with plastic carriers that a biofilm can grow on.
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.
Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...
