Latest Patents

Madhan's latest patents include an "Apparatus for filtration and disinfection of sea water/ship's ballast water and a method of same." This invention provides an apparatus and method for filtration and disinfection of ship's ballast water, such as sea water, based on hydrodynamic cavitation. The apparatus comprises a vortex diode with a tangential entry port and an axial outlet port with single or multiple bleeding holes. The disinfected water may be re-circulated through the system for additional disinfection or released from the tank into the surrounding waterways. The disinfection of seawater/ship's ballast water is achieved through filtration and hydrodynamic cavitation, and the method does not involve the use of any chemicals or any chemical reaction. The invented apparatus and method are simple, eco-friendly, and can be fitted onto existing intake and discharge systems of any ship with minor modifications. It poses no risk to the health of the ship's crew unlike chemical methods and requires no special skill or additional manpower for its operation. The apparatus and method are capable of effectively sterilizing hazardous organisms contained in ballast water stored in a ballast tank. Another significant invention is the "Controlled thruster driven profiler for coastal waters." This device serves as a controllable variable speed thruster-driven oceanographic profiler for coastal waters, measuring the vertical structure of chosen properties of the oceanic water column.
