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.
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.
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 ...
The startup is in the process of raising its Series B amid climate-driven droughts. Heck, much of the West is abnormally dry or worse , even after record-setting storms that’ve hammered ...
In California, for example, the four billion gallons of wastewater generated daily from the state’s homes and businesses, storm drain and roof-connected runoff, makes its way through more than ...
The engineer's cost estimate for the project's first phase was about $44.7 million. ... The wastewater treatment facility has seven full-time employees and serves more than 18,000 homes and ...
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 original Blue Plains facility opened in 1937 as a primary treatment facility. [2] It discharged under 100 mgd, serving a population of 650,000. Population increases in the 1950s led to the construction of secondary treatment units in 1959, with an expanded discharge capacity of 240 mgd. In the 1970s a major expansion commenced that led to ...
