These facilities were planned and constructed in the late 1990's through the early 2000's to contain and treat wet-weather wastewater flows which originated in the legacy combined sewer areas of the Detroit metro area. [13] The City of Detroit was originally developed and as water and sewer services grew within the existing municipal boundary ...
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]
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 ...
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.
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 ...
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 ...
So far the Detroit Water Project has collected $170,000 for over 900 Detroit families. Bell says the organization hopes to expand to even more cities and help make water a human right in the ...
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.
