Abstract

The invention concerns a method for maintaining metastable liquids contained in tanks, both for curative action on layers of sediments already formed and for preventive use for eliminating cause and effects. The invention is characterised in that the metastable product contained in a tank is sucked at a predetermined level of the volume of said product liquid phase, using a suction tube (1) connected to a pump (6) suction (01), and immediately re-injected under pressure into said volume of product contained in said tank using the same pump and injection nozzles (7) connected to the pump discharge (02) via an injection tube (2) arranged, preferably concentric, in said suction tube (1).
