In a metal processing industry, raw metal materials are processed into various types of machine components. Typically, cutting fluids or oil are used in the metalworking process and one can expect to find suspended solids, transition metal ions, and oil in the wastewater.
Typical reductions of different categories of substances are presented below:
• Suspended solids: 90+%
• Transition metal ions: 90+ %
• Oil index: 90+ %.
