Page: 1 Ammonification (N mineralisation)
N is generally separated from organic N compounds in the form of NH{}3, certain microorganisms can also separate NH{}4{} from the amino acids contained in proteins (deamination) or release it by urea hydrolysis. H{}2{}NC(O ...

Page: 1 Mechanical purification
mechanical component of waste water purification is used to remove solids and already starts in the sewer network rebwp8:1 Sewerage . In the plant itself, screens rebwp8:1 Screens and sieves rebwp8:2 Sieves first separate out coarse dirt ...

Page: 1 Screens
Bulky objects such as pieces of wood, textiles, shoes, cans and also finer (mostly twodimensional) waste such as fibres and the like get into the sewer network rebwp8:1 Sewerage in particular via street drains and manholes and must be retained at the inflow of the sewage plant ...

Page: 3 Denitrification
Aerobic rebwp8:Oxygen content nitrification rebwp8:2 Nitrification is followed by denitrification in an anoxic rebwp8:Oxygen content basin (no dissolved O{}2, nitrate acts as the O{}2 source). Here, NO{}3{}\ is reduced by heterotrophic Cdegrading bacteria ...

Page: Bar screens
classical screen in waste water purification is the bar screen. A grid of flat bars (bar spacing 430 mm), which is angled at approx. 60°, retains the screened material. The latter is lifted off with a mechanically operated rake and thrown onto a conveying ...

Page: Basket screens
basket screen, which is inserted at an angle in the inflow channel, consists of flat bars which are bent in a circular shape (mesh sizes 520 mm). The clearing cycle is triggered by the difference in water level upstream and downstream of the screen in this case too ...

Page: Combined system
Contaminated and rainwater is collected in a sewer system. When the weather is dry, all the waste water goes to the sewage plant, when it rains, some of the waste water goes to the sewage plant, but some goes directly into the receiving water course. \\ \\ !UBT408MischsystemKanal.jpg border ...

Page: Quantity of waste water
amount of waste water produced over time varies depending on water consumption from industry and households, precipitation (in particular rain), ... . Variations can be daily, weekly and seasonal and depend a great deal on the size of the catchment area. Whereas for example in small ...

Page: Separate system
case there are two separate sewer systems the contaminated water collector which leads to the sewage plant and the rainwater collector which conducts rainwater (from roofs and storm drains) directly into the receiving water course. \\ \\ !UBT406TrennsystemKanal.jpg border=1! This means that no dirty ...
