ABSTRACT:
The present invention is a process for purifying a fluid, particularly an industrial coolant fluid, contained within a contaminated mixture which includes mechanically emulsified as well as free or floating oil and various solid matter including metal fines. The process includes several steps for separating and recovering the coolant fluid from the mixture generally by fluid displacement and centrifugal separation. Recovered coolant fluid is regenerated with freshly made coolant fluid and any stored, recovered coolant fluid not immediately reused is recycled through a portion of the system to prevent any degradation of the stored fluid.
