Oxipur

Plants with acid retardation resins, for the treatment and reuse of Anodic Oxidation or Acid Pickling bathes by the removal of aluminum salts dissolved.

OXIPUR for Aluminum Anodizing

Application:   

Anodizing bathes containing:

  • H2SO4 ≥ 200 g/l
  • Al 12-15 g/l

An OXIPUR unit is a small, device that connects directly to an anodising tank, continuously removing Aluminum as it dissolved.
The heart of the OXIPUR unit, the resin column has the ability to absorb Sulfuric Acid while rejecting a solution of weakly acidic to waste. The acid can readily be recovered from the resin with a simple water wash.
OXIPUR unit has the flexibility to be connected to one tank or several tanks.

The efficiency of the OXIPUR acid recovery system is up to 98%

Benefits:

  • Most efficient process available
  • Maintain low Al concentration
  • Improve finish quality
  • Reduce electrical consumption
  • Recovery up to 98% of H2SO4
  • Saves lime for depuration
  • Dramatic reduction of depuration sludges
  • Avoid any shutdown of the line

OXIPUR for Aluminum Anodizing is propaedeutic to ZLD (Zero Liquid Discharge) technology

  • OXIPUR for Metal Pickling

Application:    Stainless Steel Pickling Bathes containing:

  • H2SO4             ≥ 120 g/l
  • HF ≥ 40 g/l
  • Fe2+/Fe3+ 50 g/l

An OXIPUR unit is a small, device that connects directly to an anodising tank, continuously removing Fe2+/Fe3+ as it dissolved.
