Working Fluids (MWFs)
Back in 1990, newspapers in Iowa reported a milky-white, oily substance that someone had covertly dumped in the southeast-side storm sewer. Reports also said the substance did not pose any danger to the water supply near Emerald Avenue SE and 32nd Street Drive.
Authorities had nevertheless cited regulations that required the offender party to pay hefty penalties. Investigators later identified the whitish, innocuous looking culprit as waste cutting fluid alias metal working fluid (MWF) alias coolant.
Now, MWFs are an inseparable part of machining operations such as cutting, milling, and grinding, for they maintain the temperature of the workpiece and the tools while also flushing away the unacceptables born out of machining.
Most cutting fluids are water soluble and, with use, get loaded with chips, fines, swarfs, oils, greases, and microbes. Through all this, they lose their desired properties and have to be disposed. Nothing dubious about this.
