摘要： The development of sludge in phosphating baths is prevented by continuously diverting a partial volume of the baths into a separate device comprising three open chambers: an oxidation chamber where the solution is treated with an O.sub.2 -containing gas to oxidize the iron (II) of the solution of iron (III), which precipitates as phosphate; a conditioning chamber in which the iron (iii) phosphate precipitate formed in the oxidation chamber is agglomerated into a readily sedimented form; and a sedimentation chamber in which the sediment formed in the conditioning chamber is separated from the remaining liquid phosphating solution. This solution is then replenished with phosphate layer-forming components, and the replenished solution is subsequently recycled to the phosphating bath.
