204, Chemistry: Electrical and Wave Energy, appropriate subclasses for processes of electrodialysis or electrolysis.

210, Liquid Purification or Separation, appropriate subclasses for processes in general for liquid purification or separation of liquid phases. The line between Class 210 and Class 588 is that, if there is a specific statement in the claim that hazardous or toxic waste is destroyed, separated, or converted into an environmentally safe

substance, the process is placed in Class 588; however, if purified liquid, e.g., water, is obtained as a desired product, place the process in Class 210.
