ferrous sulphate
First, the product introduction
Ferrous sulfate is an inorganic compound with the chemical formula FeSO4, that is, the blue-green heptahydrate FeSO4?7H2O. Ferrous sulfate is a white powder, containing crystalline water is light green crystal particles, crystals commonly known as "green alum". Ferrous sulfate relative density 1.898, melting point 64 °C, soluble in water, aqueous solution is light green.
Second, product performance
1. Ferrous sulfate water treatment agent has strong adaptability to various water quality, and has a remarkable effect on micro-pollution, algae, low temperature and low turbidity raw water purification, and is especially good for high turbidity raw water purification.
2. The purified water quality is better than that of inorganic coagulants such as aluminum sulfate, and the cost of water purification is 30-45% lower than that of aluminum sulfate. Flocs form fast and settle fast.
3, excellent water purification effect, good water quality, no chlorine and other harmful substances.
4. There is less salt in the treated water, which is conducive to ion exchange treatment, excellent coagulation performance, dense alum flower, and fast sedimentation rate.
5. De-turbidity, decolorization, degreasing, dehydration, sterilization, deodorization, algae removal, coD, BOD and heavy metal ions in water have significant effects.
Third, the use of the product
Ferrous sulfate products are mainly used in water purifiers, disinfectants, iron catalyst catalysts, compound fertilizer additives, and the processing of ferrous sulfate monohydrate. It is used as a fertilizer, herbicide and pesticide in agriculture, and is mainly used for the treatment of smut disease in wheat.
1, ferrous sulfate as a water purification flocculant: flocculation effect is good, has a good ability to decolorize, but also has the removal of heavy metal ions, degreasing, phosphorus removal, sterilization and other effects, especially for the decolorization of printing and dyeing wastewater and the removal of COD, ferrite co-precipitation of electroplating wastewater, etc. The effect is obvious, and its price is cheap, which is the well-deserved preferred product for wastewater treatment such as printing and dyeing, electroplating and so on.
2. Ferrous sulfate can also be used as food additives, pigments, raw materials for the electronics industry, soil amendments, and industrial catalysts
