Claim:
1. A method of subsiding, and moving in at least one predetermined direction, foam resulting from an industrial process and accumulating on the surface of a liquid associated with that industrial process, the method comprising: establishing a foam-displacement direction and a foam-displacement path along which foam resulting from the industrial process is to be displaced as the foam accumulates on the surface of the liquid associated with the industrial process; providing a set of fluid-spray sources including at least first and second fluid-spray sources from which a foam-subsiding fluid can be selectively ejected under pressure; arranging the fluid-spray sources serially above the surface of the liquid associated with the industrial process, and orienting each fluid-spray source, such that foam-subsiding fluid ejected from each fluid-spray source is sprayed in a spray pattern that is centered about a spray axis and representable by a spray vector extending along the spray axis and having (i) a non-zero component of spatial extension directed perpendicularly to, and downwardly toward, the liquid associated with the industrial process and (ii) a non-zero component of spatial extension directed parallel to the surface of the liquid associated with the industrial process and in the foam-displacement direction, wherein the serial arrangement of the fluid-spray sources defines the foam displacement path; and ejecting foam-subsiding fluid from the fluid-spray sources such that foam impacted by foam-subsiding fluid ejected from the first fluid-spray source is wetted, partially subsided and displaced in the foam-displacement direction toward the spray being ejected from the second fluid-spray source by which the foam is further wetted, subsided and displaced in the foam displacement direction.
