| 1. A method for the physical and biological treatment of an organic effluent whereby said effluent is decomposed by microorganisms
in at least one biological treatment zone, characterized in that:
a) a fraction of the biomass derived from said biological treatment is recovered,
b) a compression reservoir is filled with this biomass fraction,
c) this compression reservoir is isolated,
d) this compression reservoir is subjected to a very high pressure (with or without the presence of gas) so to destroy or
damage the microorganisms in said biomass fraction,
e) this compression reservoir is allowed to return to atmospheric pressure, and
f) said biomass fraction thus treated is reinjected into said biological treatment zone, or into one or more other biological
treatment zones.
