1. An apparatus for filtration and disinfection of sea water/ship's ballast water, which comprises a water intake means (17 & 18) consisting of a ballast water intake source (17) and pump means (18) connected in series through a pressure gauge (3) and check valve(s) to a tangential inlet port of a cavitation chamber of the form of vortex diode (5), optionally through a heat exchanger (4), characterized in that the said vortex diode cavitation chamber (5) essentially being provided on the periphery with single or multiple bleed holes of diameter(s) being in the range of 0.04 to 0.25 times the chamber depth, the output of the said vortex diode cavitation chamber (5) being passed through an axial outlet port to a quality check point (6) and through check valve(s) (7) to a ballast tank (8), the output of the said ballast tank (8) being connected to a discharge pump (9) through check valve(s) to a discharge outlet and the bleed holes output from the said vortex diode cavitation chamber (5) being connected to the said intake source (17).
