Centrifugal, ferrous and non-ferrous centrifugal type comparison: first, Centrifugal, ferrous sulfate, ferrous content is high, generally around 90%, rather than the centrifugal type of ferrous sulfate, ferrous content is generally around 85%, in Under the premise of up to the same effect, centrifugal type with a smaller amount of ferrous sulfate. Second, the centrifugal type of ferrous sulfate look beautiful, are generally not water ferrous sulfate, warehouse and ground pollution. Instead of ferrous sulfate centrifugal type usually water, free water and ground influential warehouse. The third water-drying ferrous sulfate, ferrous sulfate centrifugal type centrifugal type save time than non ferrous sulfate is longer, non-centrifugal type faster oxidation of ferrous sulfate, the appearance is easy to turn yellow. After investigation we ferrous sulfate manufacturer's technical staff showed that the use of ferrous sulfate in the treatment of wastewater containing heavy metal ions when the decomposition of ferrous sulfate in wastewater divalent ferrous ions have a strong redox, can be part of the heavy metals such as divalent copper ions, hexavalent chromium ions are not pipelined ferrous sulfate, reduced to a non-soluble substance and other Fe (OH) 3 precipitate. In addition there is an aqueous solution of ferrous ions and dissolved oxygen oxidized to the ferric ion water purifying dry ferrous sulfate, ferric ion hydrolysis after the formation of polynuclear complexes and heavy metal contaminants in water flocculation and coagulation reaction generates hydroxide precipitation, while ferric ions also undermine wastewater chromophore, a good bleaching effect. In dealing with such waste water ferrous sulfate is a chemical reaction mechanism to achieve the above remover Wastewater process of heavy metals. No running water ferrous sulfate, ferrous sulfate heptahydrate (certified), Xinyu Prime ferrous sulfate provided by the Hubei Environmental Engineering Limited. Environmental Engineering Co., Ltd.
