Abstract (en)
[origin: FR2773725A1] The system of generation and circulation of a foam is designed to function at pressures lower than or equal to atmospheric. The foam can be prepared for cleaning or decontamination purposes. A process for the generation of a foam from liquid and gaseous phases in which the phases are aspirated through a porous packing material. The foam can be circulated to a primary extremity of the installation and thence to a secondary extremity. The depression is created, by means of a vacuum pump, beyond the second extremity. Independent claims are also included for the foam generation unit and the installation for circulation of the generated foam.
