The polyferric sulfate effect in industry metallurgical wastewater

In the metallurgical process,the treatment of industrial wastewater is very complex, to reach the very obvious treatment by applying poly ferric sulfate, whether it is the middle or final disposal, the auxiliary treatment method of adding medicament.
Below only below only treated industrial wastewater metallurgy commonly described. Including water clarification agent and coagulant aluminum salt, mixed reagent of metal salts: aluminum sulfate, poly ferric sulfate, ferric chloride salts, mainly has:, ferrous sulfate, ferric sulfate
Other: copper sulfate, copper sulfate + lime ozone polymer flocculants of inorganic polymer flocculants are: polyaluminium chloride, polyaluminium ferric chloride, basic aluminum chloride organic polymer flocculants are: polyacrylamide (anionic polyacrylamide, cationic poly acrylamide) referred to as PAM, also known as the three flocculants. For the polymer flocculant, can be used alone, can also be combined use by means of PAC+PAM, effect is more obvious.
Research shows that, for some water, if you adjust pH in the best state adding acid or modified or lime, or for neutralizing acid alkali wastewater, namely in acidic wastewater with lime or NaOH, while in alkaline wastewater with H2SO4 tends to neutral, it can achieve the best results.
The metal salt coagulant, coagulant and flocculant are 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.
