How is phosphide sludge, a waste product in phosphating, generated?

I’m a beginner in the phosphating industry; I’m asking the experts to tell me which type of phosphating plants generally produce phosphide sludge Thank you
It is mainly ferric orthophosphate. Different precipitates occur in phosphating solutions. Last year, there was lead phosphide poisoning in the military industry; after a month of trouble, we had to change the formula.
