1. A foam generating device, comprising:
a housing;
a cartridge assembly received by the housing, the cartridge assembly configured to receive a solution and define an agitation flow path of the solution through a plurality of stages of agitation media, thereby increasing a quantity of a gas in the solution to produce an agitated solution; and
a conditioning assembly received by the housing and configured to receive the agitated solution from the cartridge assembly, the conditioning assembly defining an adjustable tortuous flow path comprising a plurality of cylindrical discs configured to sequentially receive the solution, each of the discs defining a plurality of radial ribs on a first side and on a second side opposite the first side, the first and second sides separated by a floor, and a disc passage defined in the floor,
wherein the conditioning assembly is adjustable such that in a first position of the conditioning assembly, the tortuous flow path comprises a first quantity of radial ribs of the plurality of the radial ribs such that the agitated solution travels along each of the first and second sides of the plurality of discs and is obstructed by the first quantity of the plurality of radial ribs during travel thereby defining a first tortuous flow path length,
wherein in a second position of the conditioning assembly, the tortuous flow path comprises a second quantity of the plurality of the radial ribs different from the first quantity such that the solution travels along each of the first and second sides of the plurality of discs and is obstructed by the second quantity of the plurality of ribs during travel thereby defining a second tortuous flow path length different from the first tortuous flow path length, and
wherein the quantity of gas in the solution exiting the first tortuous flow path or the second tortuous flow path is increased relative to the to the quantity of gas in the agitated solution.
