A new method of wastewater treatment using electric discharge in the water cavitation field formed by a large number of micro bubbles generated by high-speed water flow is proposed in this paper. Indigo carmine solution, which is a type of dye, with a concentration of 9 mg/liter was used as the specimen solution for demonstration of water treatment. The total volume of solution and the average speed of solution in the cavitation field were 20 liters and about 7.4 m/s, respectively. An absorbance decrease rate of 96% was obtained in 50 min of treatment time at the electrode distance of 2 mm and discharge power of 16 W. It was also found that the efficiency of decolorization was improved by changing the electrode location. © 2013 Wiley Periodicals, Inc.

This paper describes the development of ballast water treatment systems using interaction of bubbles, shock waves and discharges. In this development, we have cavitation flows during nozzle and diffuser part (reactor) and discharge in this cavitation area. The aim of this investigation is to satisfy the IMO standard for ballast water treatment by using our special cavitation discharge water treatment system, and to modify the geometry of reactor part in the circuit by using simple measurement method of the bubble density and diameter. In this paper, it is concluded that (1) the disintegration rate of plankton (more than 50 μm) by using cavitation discharge is satisfied in IMO standard (D-2), (2) by simple measurement method, the result of bubble density distribution in the reactor almost agrees with the position of electro node for discharge optimized with efficiency in the previous experiment. © 2012 The Japan Society of Mechanical Engineers.
