The polymeric ferric sulfate treatment reach best use in metallurgical industry

Common wastewater treatment agents in metallurgical industry include: ferric chloride, ferrous sulfate, ferric sulfate(Poly ferric sulfate), there are other: copper sulfate, copper sulfate + lime ozone polymer flocculants, organic flocculants are: polyacrylamide (anionic polyacrylamide, cationic polyacrylamide) referred to as PAM, also known as the three flocculants. Inorganic polymer flocculants are: polyaluminium chloride, polyaluminium ferric chloride, basic aluminum chloride as flocculant, can be used alone, can also be combined use by means of PAC+PAM, effect is more obvious.
Metal salt coagulant, coagulant and flocculant used in non-ferrous metal waste water treatment, metallurgy industry high turbidity sewage treatment, waste water treatment, such as ore sintering plant dust removal wastewater treatment, the coking dust removal wastewater treatment, oxygen top blown converter dedusting wastewater treatment, BF gas washing water treatment projects.
In the metallurgical process,the treatment of industrial wastewater is very complex, but the very obvious effect will reaches by polyferric sulfate, whether it is the middle or final disposal, usually use adding medicament as auxiliary treatment method .
Through a lot of experiments, for some water, if the treat is by adding acid or being modified or lime to adjust pH in the best state in the beginning, or for neutralizing acid alkali wastewater, namely in acidic wastewater with lime or NaOH, while in alkaline wastewater with H2SO4 tends to neutral, then polyferric sulfate coagulation treatment can achieve the best results.
