A review of the Material Safety Data Sheets (MSDS) for the chemicals used in, and prior to, the conversion coating process indicates that a wide range of elements can be expected to be present in the wastewaters and sludges resulting from wastewater treatment. For example, some of the specific chemical constituents found in motor vehicle manufacturers’ F019 sludge, include nickel, fluoride, zinc, barium, copper, chromium, tin, formaldehyde, lead, mercury, and xylenes.
What hazardous materials are found in F019 wastewater sludge from motor vehicle manufacturers?
