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]
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.
The Detroit Police Department has to adopt new rules curbing its reliance on facial recognition technology after the city reached a settlement this week with Robert Williams, a Black man who was ...
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 ...
Baswood BioViper(TM) Wastewater Pretreatment System at the Dr Pepper Snapple Group Houston bottling plant (Photo: Business Wire) With digestion rates of 75 to 90 percent, the Baswood system ...
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 ...
