Class Information
Number: 134/10
Name: Cleaning and liquid contact with solids > Processes > Including regeneration, purification, recovery or separation of agent used
Description: Processes in which the treating agent used is subjected to a treatment after use to (1) regenerate the same, (2) purify the same in any way, (3) recover the same, or (4) separate the same from contaminants derived from any source (usually the work treated whether the agent is to be reused or not, and even though the ingredients separated from the work are recovered for use). The removal of the work from the treating agent is not considered as any of such operations.
