Product Description

The fluxing bath is being polluted by acid residues and above all by dissolved iron. Consequently it makes the quality of the galvanizing process worse; moreover iron being entered by a polluted fluxing flow into the galvanizing bath binds itself with zinc and precipitates to the bottom, thus increasing dross.

A continuous treatment of the fluxing bath will help you get rid of this problem and cut the zinc consumption dramatically.
The continuous depuration is based upon two combined reactions an acid-base reaction and an oxide reduction which correct fluxing acidity and simultaneously cause the iron to precipitate.

The mud collected at the bottom is regularly being tapped and filtered.

ANNUO has come up with efficient solutions to continuously abate iron in the flux by adding suitable reagents in the tank, while a separate filter press extracts the oxidized iron on line. A good design of the filter press allows to extract iron without intercepting the indispensable Ammonium and Zinc Chlorides used in flux solutions. Managing the iron abatement system also allows to keep ammonium and zinc chloride contents under control and suitable balanced.
Flux regeneration and filter press systems in the ANNUO plant are dependable, easy to use and to maintain, so much so that even inexperienced operators will be able to handle them.
