Page: 1. Simultaneous aerobic sludge stabilisation
activation plants with simultaneous sludge stabilisation the activation basin rebwp8:Activated sludge method is also the sludge stabilisation reactor. They operate without a primary sedimentation basin as otherwise primary sludge would be produced which have to be stabilised again separately ...

Page: 1. Sludge concentration
preliminary concentration stage acts to minimise the energy demand for heating the water with ATS or mesophilic digestion. A subsequent concentration stage can follow a stabilisation stage

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 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. Separate aerobic sludge stabilisation
age of the sludge is not sufficient for stabilisation, drawn off excess sludge can be aerated in a separate basin (0.5 mg/l O{}2) until it is nonputrefiable. Total stabilisation time = sludge age in activation stage residence time in stabilisation basin ...

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 ...

Page: 3. Aerobic-thermophilic sludge stabilisation
method is suitable for when decontamination is the objective. Good preliminary concentration is particularly important. Sludge which is produced is aerated in a closed tank (air or O{}2). When let out the sludge is conducted via a heat exchanger which preheats the freshly ...

Page: 3. Sludge drying
order to be able to remove even more water than with mechanical dehydration, the remaining sludge water must be evaporated. A lot of energy is needed for this, which is why it is only used in larger plants. The great reduction in volume is advantageous. The combination of drying and burning ...

Page: 3 Hopper-bottom basins
type of sedimentation basin, mechanical sludge clearing is no longer necessary because the bottom is angled so greatly (at least 60°) that the sludge slides towards the bottom of the hopperbottom basin by itself. The waste water is guided towards an inflow structure in the centre ...

Page: 4. Unheated digestion tank
Methanogenic bacteria are also viable at low temperatures rebwp8:Temperature complete digestion rebwp8:Sludge digestion (anaerobic) is also possible at normal waste water temperatures and stabilisation times of 90120 d. Twostorey system (Imhoff tank) These are very rare ...
