Why should I use Diffusion Dialysis with
Sulfuric Acid Anodizing process?
Diffusion Dialysis is excellent for
the recycling of sulfuric acid anodize solutions. Diffusion Dialysis
provides improved anodize quality, reduced burning, reduced additive
consumption, consistent anodized color and consistent anodic thicknesses,
with cooler and less energy demanding baths, while eliminating production
down-time associated with the dumping and remaking of the anodize bath.
The passive, continuous Diffusion Dialysis
process enables the anodizer to efficiently remove and control the dissolved
aluminum content in the bath while recovering and returning a high
percentage of the sulfuric acid back into the process bath. The Diffusion
Dialysis process also removes and controls other contaminant build-up in the
anodize bath, such as: copper, iron, lead, magnesium, manganese, phosphate,
silicon and zinc, while producing a minimum of rejected waste by-product for
subsequent treatment and disposal.
