ABSTRACT:
A unique bubble production system and method for sampling and cleaning la regions of "dirty" or polluted bodies of water, or for otherwise sampling them for other biological activity. This is achieved by the use of millions to trillions of tiny chemical coated particles which are usually dispersed in air by suitable means to effect predetermined patterns of the particles and resultant bubble region as they descend in the water. The particular character of the particles and their selected dispersal mode assure the homogeneous generation of large concentrations of millions to trillions of bubbles throughout a predetermined volume of the water body so as to generate a planned and controlled bubble spectra for a selected applicational purpose. A bubble spectrum is a plot of the number of bubbles per volume as a function of bubble diameter.
