This foam-generating device is easily transportable, free from fluid or power supply constraints, and able to supply a foam such as viscous foam with a high (low liquid fraction), time-invariant (low liquid fraction). The gas is withdrawn compressed from a cylinder, and a fixed fraction of its flow is used to drive a pneumatic pump which draws in the foaming liquid. The foam is formed in a mixer containing free-moving solids shortly before the ejection end of the device. The mixer has highly mobile balls in a cage of much larger dimensions; it is suitable for producing foam with a high overrun. Application: decontamination and depollution of large surfaces, buildings or indoor or outdoor structures.

The present invention relates to a system (300), method and generator (301) for producing solvated nanoclusters of a guest substance. The method comprises providing a container (302) containing a plurality of surfaces (304) distributed therein; introducing a solvent (103) within which the solvated nanoclusters are to be generated into the container such that the solvent comes in contact with the surfaces; and distributing a fluid guest substance within the solvent, wherein the plurality of surfaces comprises random packings or structured packings or both, wherein the packings are made of or coated with (i) permanent-magnetic material or (ii) dielectric material that has a quasi-permanent electric charge or dipole polarisation.

A water processing system is provided for processing or conditioning water to be distributed to a downstream function or system. The system includes a water processor with a conditioning element disposed inside a housing between an inlet and outlet of the housing. The conditioning element includes a series of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plates may have different configurations of apertures. Optionally, a mixer injector introduces a gas, in the form of gas bubbles, into the water flow upstream of the water processor. The injector introduces additional gas volume in the form of relatively large bubbles, which are subsequently split into smaller bubbles (including nano-bubbles) in the water processor.

An air-water current purifying device allows the size of the bubbles from the mixture to be reduced includes an inlet for the air-water mixture; a first filter occupying the cross-section of the device, with a plurality of holes; a first expansion chamber after the first filter; a second filter with the same characteristics and arrangement as the first filter and located after the first expansion chamber; a second expansion chamber after the second filter; a third filter after the second expansion chamber, with the same features and arrangement as the first and second filters; a third expansion chamber after the third filter; a pressure-regulating valve arranged at the outlet of the device; and a regulating flywheel that allows the valve to be closed and opened.
