Page: 1. Upstream denitrification
Waste water, return sludge and internal recirculation are mixed in the denitrification basin. Both denitrification and nitrification rebwp8:2 Nitrification basins can be configured as cascades. To increase operating flexibility, it can be possible for the last parts of the denitrification basin (in the direction of flow ...

Page: 1. Upstream precipitation
Pdeficit should be avoid in the activation basin (otherwise e.g. bulking sludge rebwp8:Bulking sludge can occur). \\ \\ !UBT484PVorfällung.jpg border=1

Page: 1 Long sand trap
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 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 P incorporation in biomass
P compounds are vitally important for bacteria rebwp8:Bacteria to build their physical body (empirical value BOD5 rebwp8:BOD5 : N : P = 100 : 5 : 1). As the phosphate content in domestic waste water is however higher, only approx. 3040 ...

Page: 1 Rectangular basins
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: 2. Cascade denitrification
Waste water flows through two or more activation basins (each with an upstream or simultaneous denitr. stage) conse­cutively, with the waste water being fed in a divided manner to the denitr. basin (à internal recirculation omitted). High O ...

Page: 2. Simultaneous precipitation
Chemicals are directly added tot he activation basin (or tot he return sludge) simultaneously with the biological degradation P rebwp8:3 Biological P removal is removed (up to > 85%). \\ \\ !UBT485PSimultane Fällung.jpg border=1

Page: 2 Chemical P removal
P is precipitated out as phosphate by adding Fe or Al salts. Disadvantages here are the costs for the precipitant and the salting of the water (more Cl, SO4\ in the outflow). Acidic precipitation salts (such as FeCl{}3) result in consumption of hardness and therefore reduced buffer capacity ...

Page: 2 Round basins
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 ...
