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.
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 ...
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 ...
Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1]: 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
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 ...
Oxyle wants to help solve the crisis with a new wastewater treatment that removes micropollutants. The Zurich-based startup announced today $3 million in pre-seed funding that it will use to bring ...
Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. [ 1] Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of ...
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.
