ABSTRACT:
A system and process for managing metalworking fluids is disclosed. The system has a metering device for supplying desired amounts of metalworking fluid components (coolants, lubricants, biocides, etc.) to the metalworking fluid of the system which has been collected from the metalworking area, and filtered. The use of a variable pump (variable in speed, volume or time) is preferred to ensure that adequate, but not excessive amounts, of the necessary components are added to the system. Preferably, the metering device is located between the outlet of the filter and the inlet of a metalworking operation. The system and process reduce consumption of the metalworking fluid, reduce costs, reduce waste generation, and increase filter performance and overall system control.
