1. A system for producing a liquid with gas bubbles, the system comprising:
a liquid inlet to receive a liquid stream,
a gas inlet to receive a gas stream,
an eductor configured to mix the liquid stream and the gas stream to a form of a liquid-gas mixture, and
a mixing column comprising:
an input configured to receive the liquid-gas mixture from the eductor,
an output, and
a stack of filling layers positioned between the input and the output, configured to reduce a size of gas bubbles within the liquid-gas mixture as it flows from the input to the output, the stack of filling layers comprising a plurality of porous layers separated alternately by:
plate layers made of a first impermeable material, each plate layer having a shape of a plate distanced by a clearance from an internal wall of the mixing column to allow the liquid-gas mixture to flow from one porous layer to its neighboring porous layer via the clearance, and
ring layers made of a second impermeable material, each ring layer having a form of a ring that has a central flow-through aperture to allow the liquid-gas mixture to flow from one porous layer to its neighboring porous layer via the aperture.
