Polyferric sulfate is a very important coagulant in water treatment process. People engaged in water treatment related industries should know the precautions about it. But what are the precautions in the process of use? Do you know the precautions in the production of polyferric sulfate?

What should be paid attention to in the production of polyferric sulfate?

Some people may think that what should be paid attention to in the production of poly iron has no effect in the process of use, and it is true in fact, but it is good to know more. To talk about the matters needing attention in production, we should start from several production methods of polymerized ferric sulfate, with raw materials as the difference: first, raw materials are ferrous sulfate, sulfuric acid and catalyst; second, raw materials are ferrous sulfate and waste ferrous sulfate from titanium dioxide factory; third, raw materials are concentrated sulfuric acid and ferrous sulfate.

In summary, the points for attention in the production of poly iron are as follows: adding oxidant solution at one time to speed up the reaction speed, improve the basicity, eliminate the iron precipitate and improve the iron content of the product. Control the reaction temperature. It can prevent the decomposition reaction and precipitate when the temperature is too high, and reduce the iron content of the product. Sufficient reaction time is needed to make the raw materials fully dissolve and react to avoid false appearance.
