Subject field(s)
  • Satellite Telecommunications
  • Spacecraft
CONT

The main units of the AIC are : the focal plane assembly(FPA), equipped with a back-thinned illuminated CCD matrix and a front-end amplifier, provides the optical signal detection. A thermoelectric peltier cooler under the detector sets the operating point at-25°C ± 100 mK, the detection box(BD) which supplies the FPA with the necessary electrical signals to operate the CCD. It generates the clock waveforms from the VEU signals and filters the supplied voltage from the DSU, the video electronics unit(VEU) which processes the analog signal coming from the FPA, digitizes it on 12 bits before passing it on in serial processing to the science data processing subsystem(SDPSS). It also provides the DBs with the primary clock signal. The power conditioning of the VEU is located in the same unit, the detection supply unit(DSU) delivers relevant stabilized voltages to the 5 DUs and power to thermo-coolers from the main supply feeder of the instrument.

Subject field(s)
  • Pipes and Fittings
  • Wastewater Treatment
CONT

The sludge which settles in the settling one is returned to the aeration zones through rising recirculating ducts. These ducts house diffuser which supply the air required to set up the recirculating motive power. Recirculation flow can reach 5 to 6 times the through flow. The recirculating air is supplied through a circuit separate from the main system. The amount of sludge recirculated can therefore be regulated very easily.

French

Domaine(s)
  • Tuyauterie et raccords
  • Traitement des eaux usées
CONT

Le retour vers la zone d'aération des boues décantées dans les clarifications est assuré au moyen de gaines de recirculation ascendantes. Dans ces gaines, sont disposés des diffuseurs fournissant l'air nécessaire pour engendrer la pression motrice de recyclage. Le débit de recirculation peut atteindre jusqu'à 500 ou 600 % du débit traversier. Un circuit séparé du réseau principal fournit ce débit d'air de recyclage. La quantité de boues recirculées est donc réglable très aisément.
