Properties

Ferrous sulfate: alias: ferrous sulfate, ferrous sulfate heptahydrate, green alum, drying ferrous sulfate. It can be used as reducing agent in electroplating plant, flocculant in industrial wastewater, precipitant in printing and dyeing plant, raw material in Tiehong plant, raw material in pesticide plant, raw material in chemical fertilizer plant, fertilization in ferrous sulfate flowers, etc. It is widely used for flocculation, clarification and decolorization of printing and dyeing, papermaking, domestic sewage and industrial wastewater. Ferrous sulfate can also be used to treat chromium containing wastewater and cadmium containing wastewater Equal high alkalinity and high chroma wastewater treatment can reduce a large amount of investment in neutralization acid.
