Polyhydric Alcohol Domineralhing Plant in an Eastern chemical center, improving product quality
ΓΟΗ example, many formaldehyde producers are im: proving the quality of their product by use of ion ex change. The formaldehyde is passed through an anion exchanger which removes essentially all of the formic acid, thus making it more valuable in uses requiring low acidity.

Or, as steel fabricators have done, replace obnoxious /sulfuric acid pickling with phosphoric acid pickling— jxiadte feasible at low cost by regeneration of the bath with a Permutit ion exchange resin—and actually realize savings with the superior pickling and coating process. Again, as in the case of a textile fibre producer, recover scarce and valuable copper from waste waters—thanks to Permutit's ion exchangers!
