This supply and recycling means includes an elevator

outlet of the separation means, that is to say at the end of the grid 7. This elevator is driven by an electric motor 15.

  
Said elevator transports the elements 6 to a chute
16 in which he discharges them. This chute is sized and positioned in such a way that it ensures transport

10 mechanically. Devices 5 and 12 have comparable effects and can be used together or separately-

  
At the same time, it is introduced into the basin, continuously or not, and a discrete quantity of ele is circulated therein.

  
 <EMI ID = 31.1>

  
bacterial. By discrete amount is meant an amount formed of separate elements. As these elements can be very numerous, the contact surface between the waste water and these elements is very large. In addition to the process of purification by activated sludge, there is also a process of purification by bacterial beds in contact with the waste water. With each of the elements 6.
