A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept latterly toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is latterly offset from the longitudinal axis. The interior end of the inducer body has a concave curvature. The swept flow passage and the curved interior end induce a vortex flow in a fluid flowing through the flow passage as it exits the flow passage and into a flow passage of a conduit the that extends at an angle relative to the longitudinal axis of the inducer body.

A system includes an elongated cylindrical body having a first end extending to a second end; an outer surface and an inner surface; a thickness extending from the inner surface to the outer surface; and a plurality of openings extending from the inner surface to the outer surface. The system further includes a fluid injection apparatus disposed within the elongated cylindrical body, the fluid injection apparatus is configured to pass fluid through the openings.

A method for treating effluent provides the effluent as an input to an apparatus having a vortex diode with aeration. The apparatus induces a cavitation assisted with aeration for the high rates of ammoniacal nitrogen in an orifice and the vortex diode with or without inserts/stabilizers to generate radicals, which reduce ammoniacal nitrogen of wastewater effectively during effluent treatments.

A vortex ring generation device includes a casing having a discharge port, an extrusion mechanism, and a component supply port. The extrusion mechanism extrudes air in an air passage inside the casing such that the air is discharged, in a vortex ring shape, from the discharge port. The component supply port surrounds the air passage. A total circumferential length of the component supply port is ½ or more of a total circumferential length of the discharge port. The extrusion mechanism includes a vibration plate and a drive unit that vibrates the vibration plate. The air passage includes a first passage, and a throttle passage continuous with a downstream end of the first passage. A component chamber is provided inside the casing. The component chamber contains a discharge component to be supplied to the component supply port. The component supply port is located downstream of the throttle passage.
