Page: 1 Long sand trap (REBEL WP8: Biotechnology)
Long sand traps are constructed as elongated, open channels in two parts in small plants (in three or more parts in larger plants). Baffle plates at the sand trap outflow are used to maintain the desired flow speed when inflow varies. The sand ...

Page: 1 Rectangular basins (REBEL WP8: Biotechnology)
waste water flows slowly (0.25 cm/s) and uniformly through the basin, sediment­able material separates out, float­ing material is retained by a baffle in front of the basin out­flow. The sedimented slud­ge is conveyed into the slud­ge sump ...

Page: 1 Screens (REBEL WP8: Biotechnology)
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: 2 Biological purification (REBEL WP8: Biotechnology)
early as the 19th century, waste water specialists learned about natural selfpurification processes from nature. In biological purification, dissolved and fine suspended material, as well as colloids (which do not sediment out by themselves), are converted into sedimentable material rebwp8 ...

Page: 2 Nitrification (REBEL WP8: Biotechnology)
During nitrification, oxidation of the ammonium into nitrate takes place by various autotrophic microorganisms (nitrifiers) and is carried out in the activation basin. The nitrifying bacteria use CO{}2 for building cells and reduced organic N compounds as an energy source. The maximally ...

Page: 2 Round basins (REBEL WP8: Biotechnology)
case the waste water is guided to the centre of the basin and flows outwards uniformly in all directions to the basin edge. Outflow channels run around the outer part of the basin. A moving scraper bridge pushes the sludge towards a sludge sump in the centre of the basin ...

Page: 2 Round sand trap (REBEL WP8: Biotechnology)
round sand trap, the waste water is introduced at the periphery, as a result of which a cyclic flow is produced and the deposited sand is displaced towards a funnel in the centre of the basin (teacup effect), where it can also be washed and is conveyed to a dehydration apparatus with a compressed air ...
