Abstract: An apparatus and method of measuring, monitoring, recording and verifying the uptake and discharge of ballast water on marine vessels to ensure that they comply with the ballast water discharge standards set by international bodies, the apparatus includes an arrangement of small sampling pipes, valves, sampling pump, flow meter, Ballast Water Monitor, Ballast Water Sensors Module and Controller. The method comprises measuring the concentration of the bacteria and pathogens in the sampled ballast water during ballasting and de-ballasting by the Ballast Water Monitor and compared against the regulatory standards and historical data of similar ship data and ballast water data. The method also identifies and isolates specific ballast water tank that holds non-compliant ballast water so that when compliant water is available, the non-complaint ballast water shall be flushed out from the identified specific ballast water tank with the compliant water.

Abstract: A method of deriving parameters for an emulsifier for producing specific water-in-fuel emulsions consistent with emulsions produced by a reference emulsifier is disclosed herein. In a described embodiment, the emulsifier and reference emulsifier includes a desired mixing chamber and reference mixing chamber respectively for mixing fuel and water. The method comprises, at steps 602 to 604, deriving a diameter of the desired mixing chamber for the emulsifier based on a diameter of the reference mixing chamber of the reference emulsifier, the derived dimension of the desired mixing chamber being one which creates a turbulent type flow at the mixing chamber. At step 605, the method includes calculating dimensionless water particle size from the derived dimension and at step 606, deriving nozzle dimension of the emulsifier for a plurality of water nozzles for injecting the water into the oil at the mixing chamber from the calculated dimensionless water particle size.
