ABSTRACT:
An apparatus for activating silicic acid contained in water, in which a helical antenna which generates an oscillating magnetic/electric field by use of a high-frequency power source and has a length 1, 1/2 or 1/4 times as long as the wavelength of the high-frequency wave is disposed in the direction of the central axis of a cylindrical tank; a water inlet pipe provided with a water injection pipe member for introducing water into the tank is disposed at the top or in the upper part of the side wall of the tank; a water drain pipe is disposed at the bottom or in the lower part of the tank; and the angle .theta. formed by the axis of the injection pipe and the straight line connecting a point where the axis of the injection pipe and the circumference of the tank intersect and the axis of the cylinder of the tank satisfies the equation: 0.degree.<.theta..ltoreq.90.degree., so that water supplied into the tank forms a whirling flow that crosses the magnetic field at a right angle. Silicic acid or silicate ion contained in water can be activated in an highly effective manner by using the simple apparatus according to the invention.
