CIE Technologies - OXIPUR: Units with chromatographic acid retardation resins for treatment and reuse of anodizing or acid pickling baths by removal of dissolved metal salts.

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 tanks, continuously removing Aluminum as it dissolved: into the process bath as a result of anodizing.

The heart of the OXIPUR unit, the resin column has the ability to adsorb Sulfuric Acid while rejecting the Aluminum salt to waste. The acid can readily be eluated from the resin by simply washing with water.

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
Reduction in H2SO4 consumption
Reduction of lime consumption to neutralize
Dramatic reduction in sludge production
Increase productivity by eliminating bath dumps/reformulation

OXIPUR for Aluminum Anodizing is a preclude 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 a pickling bath continuously removing Fe2+/Fe3+ as it dissolves.

The heart of the OXIPUR unit, the resin column has the ability to adsorb Sulfuric/Hydrofluoric Acids while rejecting the iron salts 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
