.~ Utilizing electrical or wave energy (directly applied to liquid or material being treated)
DEFINITION
Classification: 210/748
Utilizing electrical or wave energy (directly applied to liquid or material being treated):
(under subclass 600) Process in which the liquid is directly subjected to an electric field or current or to a regular pulsating source of energy (e.g., irradiation, ultrasonic vibration, etc.).
(1) Note. The process of electrolysis of liquid to generate
a treating agent for a process of this class will be classified here but electrolysis to directly separate a constituent is classified in Class 205. For example, electrolysis of a liquid to produce chlorine which kills bacteria in the liquid would be classified here but removing mercury salts by plating out mercury would be classified in Class 204.
(2) Note. The wave energy must be applied to the liquid and vibrating a filter to clean it is not classifiable here but in subclass 785.

204, Chemistry: Electrical and Wave Energy, especially
450+, for electrophoresis or electro-osmosis, and subclasses 554+ for electrical or simultaneous electrical and magnetic separation or purification of a liquid or magnetic treatment of a liquid (other than separation). See section III of the Class 204 definition and section III, C, of the Class 210 definition for an elaboration of the class line between Class 204 (which encompasses Class 205) and Class 210.

742+, for electrolytic treatment of water, sewage, or other waste water. See section III of the Class 204 definition and section III, C, of the Class 210 definition for an elaboration of the class line between Class 204 (which encompasses Class 205) and Class 210.
