<p>PCT No. PCT/CA91/00269 Sec. 371 Date Jan. 29, 1993 Sec. 102(e) Date Jan. 29, 1993 PCT Filed Jul. 31, 1991 PCT Pub. No. WO92/02926 PCT Pub. Date Feb. 20, 1992.Water is treated with sound waves produced by means of a submerged plasma sparking device (16) to mitigate detrimental effects of aquatic organisms in the water. For example, the incrustation of zebra mussels may be reduced by killing the zebra mussels or creating an environment hostile to them. The plasma sparking device may have a main storage circuit (14) which includes liquid dielectric capacitors or cryogenically cooled field coils for storage. Moreover, the electrodes (50) of the plasma sparking device may be of aluminum or an aluminum alloy.</p> |
