A biofilter is a bed of media on which microorganisms attach and grow to form a biological layer called biofilm. Biofiltration is thus usually referred to as a fixed–film process. Generally, the biofilm is formed by a community of different microorganisms ( bacteria, fungi, yeast, etc.), macro-organisms ( protozoa, worms, insect's larvae, etc ...
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 ...
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.
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 ...
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 ...
Overview. The Detroit Water and Sewerage Department is a sprawling network covering 1,079 square-miles, [1] [3] servicing more than 40 percent of the U.S. state of Michigan 's population, [1] and employing nearly 2,000 people. [4] The DWSD is one of the most extensive and largest water and sewage systems in the United States. [1]
City officials on Monday kicked off the start of construction of Detroit’s first air dome sports complex. The $14 million dome, funded by the American Rescue Plan Act, is expected to open in mid ...
Trickling filter. A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime ( biofilm) to grow, covering the bed of media.
