Abstract
A sono-molecular-conversion device and method for treating waste water including (a) feeding the waste water containing organic matter through a first sono-molecular conversion device including a plurality of ultrasound transducers; (b) applying ultrasonic energy to the waste water containing the organic matter by the sono-molecular conversion device to ultrasonically collapse microsized bubbles with transient cavitation in said waste water containing organic matter to effect mineralization of the organic matter into ammonia therein by sono-molecular-conversion; (c) feeding the waste water containing the ammonia through a second sono-molecular conversion device including a plurality of ultrasound transducers; and (d) applying ultrasonic energy to the waste water containing the ammonia by the sono-molecular conversion device to ultrasonically collapse microsized bubbles with transient cavitation in said waste water containing the ammonia to effect nitrification of the ammonia into nitrates and nitrites therein by sono-molecular-conversion.
