The present invention relates to a system for processing a lipophilic fluid, more particularly to a system for processing a lipophilic fluid utilized in a fabric treating process, even more particularly to a system for processing a lipophilic fluid such that contaminants such as water, surfactants, water, body/food oils, fatty acids, and dyes can be removed from the lipophilic fluid. In other words, the present invention relates to the "cleaning up" of or purification of a lipophilic fluid such that it can be re-used in a lipophilic fluid system.
