Metal Finishing or Plating Rinse Water Wastewater System Example

Diagram of Metal Finishing/Plating Rinse Water Wastewater system

Rinse water from plating/metal finishing operations can be re-used and disposed more efficiently using a well designed wastewater system. This example system contains:

  • Rinse Water from Plating Operations Creates Wastewater
  • pH Adjust to Precipitate Metals
  • Ultrafiltration to Remove Emulsified Oils and Precipitated Metals
  • Carbon Media Filter
  • Reverse Osmosis
  • Treated Water Back to Facility for Reuse with Reject Going to POTW or EVALED® Vacuum Evaporator for Further Volume Reduction
  • For Heavily Chelated or Precious Metal Rinse Water and EVALED® Vacuum Evaporator where Distillate can be Reused for Rinse Water and the Concentrate is Reused in the Process Bath
