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 ...
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 ...
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.
The standards are technology-based, i.e. they are based on the performance of treatment and control technologies (e.g., Best Available Technology). Effluent Guidelines are not based on risk or impacts of pollutants upon receiving waters. Since the mid-1970s, EPA has promulgated ELGs for 59 industrial categories, with over 450 subcategories.
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.

Anammox is a wastewater treatment technique that removes nitrogen using anaerobic ammonium oxidation (anammox). [1] This process is performed by anammox bacteria which are autotrophic, meaning they do not need organic carbon for their metabolism to function. Instead, the metabolism of anammox bacteria convert ammonium and nitrite into ...
Membrane bioreactors are combinations of membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment. [ 1] The two basic membrane bioreactor configurations are the submerged ...
