Ferrous sulfate has very good effect in daily life, industrial production, agricultural production and water treatment. In daily life, it is mostly used as flower fertilizer, industrial production as raw material, agricultural production as fertilizer and pesticide, and ferrous sulfate has more effect on water treatment. Today, we will talk about the phosphorus removal and decolorization effect of ferrous sulfate in water treatment.

Ferrous sulfate has a very good effect of phosphorus removal and decolorization in water treatment. There is more phosphorus in urban life, but the chroma of printing and dyeing wastewater is high. Therefore, ferrous sulfate is widely used in water treatment in these two places. Ferrous sulfate also has a good flocculation effect, which can greatly remove turbidity and decontamination in sewage treatment, and it is cheap. It is one of the common water purification chemicals.

When ferrous sulfate is used for decolorization treatment, ferrous ions in ferrous sulfate will react with polynuclear compounds in dye, that is, color substances in water to produce water-insoluble substances, which will be flocculated and precipitated through the flocculation effect of ferrous sulfate, so as to achieve the effect of sewage decolorization.

The phosphorus removal effect of ferrous sulfate is that ferrous ion in ferrous sulfate reacts with phosphate or metaphosphate in sewage to form insoluble substance, which can achieve the effect of phosphorus removal.

Ferrous sulfate needs a correct method in dephosphorization and decolorization. Such as the pH value of sewage, the nature of sewage, the concentration of sewage and so on, only reasonable methods can achieve the ideal effect.
