Abstract: A sono-molecular-conversion device and method for effecting nitrification of ammonia in water, the method including feeding the water containing ammonia through a sono-molecular conversion device including a plurality of ultrasound transducers; and applying ultrasonic energy to the water containing ammonia by the sono-molecular conversion device to ultrasonically collapse microsized bubbles with transient cavitation in the water containing ammonia to effect nitrification of ammonia therein by sono-molecular-conversion.

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

Abstract: A method for reducing ammonia concentration in an aqueous medium caused by the presence of fish gill/urine discharge, fish faeces and uneaten organic fish-feed particulate matter in recirculating aquaculture tanks. Fish in fish tank water are remotely located or partially isolated from the fish tank water utilized by the sono-molecular-conversion apparatus. Transient cavitation-created, collapsing microsized bubbles generated in the fishless portion of the fish tank water completes ammonia nitrification, mineralization and denitrification therein.

Abstract: A side entry tub includes a stationary section and a movable section with a mechanism of pivoting the movable section away from the stationary section to form an opening for entry and back to the stationary section to form an enclosure for bathing. During pivoting, the movable portion is separated from the stationary section to avoid damage and excessive wear on sealing gaskets.
