ABSTRACT:
A process for recovering an industrial coolant fluid from a contaminated mixture and restoring the recovered coolant fluid to a predetermined concentration level and an apparatus for carrying out the process are disclosed. The process includes the following steps: (a) removing relatively large and heavy particulate matter from the contaminated mixture, the mixture containing coolant fluid and contaminating oils and solid particulate matter; (b) depositing the partially cleaned mixture into a first container (30) designed and constructed so that a whirlpool motion is imparted to the fluid passing through it; (c) transferring the mixture from the first container (30) to a liquid/liquid/solid separator (50); (d) recovering the separated coolant fluid from the separator (50); (e) introducing the recovered fluid into an inlet (38) of the first container (30) in a direction enhancing a fluid vortex created by the whirlpool movement of the fluid within the container (30) while permitting free oil to rise to the surface of the fluid vortex; (f) repeating steps (c) through (e) until the recovered coolant fluid has been sufficiently separated from the contaminants in the mixture; (g) then transferring the recovered coolant fluid from the first container (30) to a second container (80); and (h) restoring the recovered coolant fluid held in the second container (80) to a predetermined component concentration level.
