WASH-WATER WEIR [2 records]

Record 1 1982-03-11

English

Subject field(s)
  • Transport of Water (Water Supply)
  • Water Treatment (Water Supply)
OBS

The air scour must not be started when the water in the filter is at the level of the wash-water weir, nor must backwash be used at the same time as air scour, since in both cases large quantities of anthracite would be carried off to the drain.

French

Domaine(s)
  • Adduction d'eau (Alimentation en eau)
  • Traitement des eaux
OBS

Il est [...] impossible, soit de commencer le soufflage quand l'eau, dans le filtre, est au niveau du déversoir de lavage, soit d'utiliser un contre-courant d'eau en même temps que l'air car, dans les deux cas, on constaterait un entraînement massif d'anthracite à l'égout.
