A system for processing and reclaiming machine tool coolant wherein filtering apparatus mounted upon a portable frame is transported to the machine tool and includes pumps for cycling coolant from the machine tool coolant reservoir through coarse and fine filters to remove contaminating foreign matter, including bacteria. The apparatus includes an accumulating reservoir receiving and supplying pumped coolant and the pumps are controlled by float-operated switches maintaining a sequence of pump operation to assure efficient pump operation.

A process comprising reclaiming machine tool coolant within a machine tool coolant circulation system wherein the machine tool coolant circulation system includes a reservoir by (a) pumping the coolant from the machine tool reservoir into a first filter, (b) filtering the larger foreign matter particles from the coolant to produce a coarse filtered first filtered coolant, (c) pumping said first filtered coolant through a second filter to produce a finely filtered second filtered coolant, and (d) discharging said second filtered coolant into the machine tool reservoir until the coolant within the reservoir attains an acceptable filtered condition.
