Ferrous sulfate is generally used as the raw material for the production of polymeric ferric sulfate. In the production process, the addition of ferrous sulfate, reaction temperature and reaction pressure are directly related to the subsequent polymeric ferric sulfate products.

Ferrous sulfate heptahydrate is commonly used in the production of poly ferric sulphate, so great attention should be paid to the temperature control. Because when ferrous sulfate heptahydrate exceeds the critical temperature, crystal water will evaporate, resulting in ferrous sulfate hydrolysis. After hydrolysis, it is not ferrous sulfate, which will cause pollution. Therefore, the production of polymeric ferric sulfate needs to control the temperature strictly.

The reaction pressure also has a great influence on the production of PFS.The production process is carried out in the closed reaction tank. Heating and pressurization will cause the pressure in the reaction tank to rise continuously. Too high pressure will have a great impact on the polymerization of PFS, so it is unable to get better PFS products.

The production process of PFS is generally complex, so the product quality of PFS is also the result of many factors in production, which can not be determined unilaterally.
