A method of and apparatus for treating liquids flowing in a thin film around a source of wave energy to directly expose the liquid to the wave energy, preferably generated in whole or part by an electrical arc between carbon electrodes. In addition to the wave energy generated by the electrical arc, energy generated by cavitation of the flowing liquid may be used in treating the liquid.
