Simplify Chelate Breaking for Surface Finishing Wastewater | PRAB

Ultrafiltration provides a simplified, effective and superior solution for removing soluble heavy metals from this wastewater produced by many processes including electroplating, electroless nickel plating, printed circuit board manufacturing, metal forming operations, battery recycling, and mining operations.

The concentration and chemical form of the soluble heavy metals in a particular wastewater stream varies, depending on the industry and the mix of operations at a processing site. For example: In the plating industry, specialty chemical suppliers have developed alloy technologies to maximize the high corrosion resistance of the metal.

Ultrafiltration – Advanced Membrane Technology

Complexors used in today’s surface finishing industry make the wastewater extremely difficult to treat through conventional methods. But, unlike conventional clarifier techniques, Tubular Ultrafiltration (UF) is a very effective method of removing virtually all of the precipitated metal hydroxide/sulfides/carbonates from the wastewater stream. The resulting high-quality permeate can be fed directly to reverse osmosis equipment for reuse, reclaimed ‘as is’ or discharged to the POTW.

Membrane technology provides numerous advantages to the process of surface finishing wastewater treatment including:

  • Eliminating the need for clarifiers or lamella separators
  • Not requiring coagulants for processing
  • Reducing the volume of sludge generated
  • Lowering labor costs
  • Lowering chemical costs
  • Producing a more consistent effluent

Wastewater treatment can appear to be a daunting task, especially when heavy metals are part of the equation. Partnering with a proven expert in wastewater solutions can improve your profitability as you address an important and essential aspect of modern manufacturing.
