The object of research is colloidal soluble forms of metasilicic (H2SiO3) acid and insoluble forms of
orthosilicic acid (H4SiO4). The subject of research is the study of changes in the physical parameters of
the disperse system consisting of a colloidal form of silica, in the field of ultrasonic standing waves. The
operation mode selection is proved effect on finely dispersed system containing soluble forms of silicas,
ultrasonic oscillations in the standing wave mode for 10 minutes with an intensity of 1•104 W/m2. On the
basis of thermogravimetric data, conductivity, measurement findings of a violation of thermodynamic
equilibrium we made a conclusion on the optical density of the solutions under the influence of ultrasonic
vibrations in a dispersed system consisting of metasilicic acid. That leads to orthosilicic acid which helps
to cleanse the water from the colloidal particles of the acid and has a positive effect on the technological
properties of natural waters. The method is environmentally friendly and economically viable. This area
of physical and chemical effects is important for the development of technical solutions in matters of
purification of natural water used in enterprises of heat and electricity, as well as in in domestic sphere.
