Claim:
1. A method for treating effluent by providing the effluent as an input to an apparatus comprising a vortex diode with aeration, said vortex diode comprising: i. a chamber provided with at least one inlet as a tangential port, wherein a flow entering from the tangential port sets up a resistance mode of an operation; ii. a vortex stabilizer connected to the chamber, wherein said vortex stabilizer comprises a base with or without threads and an insert which lies within the chamber, the insert being symmetrical around an axis of an axial port having a geometrical shape formable by revolving either a straight connecting line having slope or a curved line between a point on the axis and a point lying on the base opposite to the axial port; and iii. the axial port provided in the chamber for discharging treated effluent water, wherein the vortex stabilizer has a diameter in a range of 10 to 40% of a diameter of the chamber and has a height less than 15% of the diameter of the chamber such that the method enhances reduction of an ammoniacal nitrogen content of the effluent.
