Abstract

An apparatus for treating an aqueous medium containing microorganisms comprises an intake for receiving the aqueous medium containing microorganisms. A pressure differential inducer is associated to the intake so as to receive the aqueous medium containing microorganisms with a desired level of gas saturation. The pressure differential inducer is actuatable to expose the aqueous medium containing microorganisms with a desired level of gas saturation to accelerations so as to cause cell wall rupture of the microorganisms. An outlet is associated with the pressure differential inducer for outletting the treated aqueous medium containing ruptured microorganism cells and contents. The treated aqueous medium containing ruptured cell wall of the microorganisms is disposed of and/or recycled.
