Polymeric iron sulfate is a commonly used phosphorus removal agent, commonly used in the field of water treatment. It can be used to treat sewage, wastewater, or other water bodies containing phosphorus to reduce phosphorus concentration and prevent water bodies from being affected by excessive eutrophication.
The working principle of polymeric iron sulfate is to chemically react with phosphate in water to form insoluble iron phosphorus compounds, which are precipitated to achieve phosphorus removal.
When using polymeric iron sulfate as a phosphorus removal agent, the following aspects usually need to be considered:
Applicability: Ensure understanding of the chemical properties of the water body to determine whether polymeric iron sulfate is suitable for the water body.
Dose control: Determine the appropriate dosage, too little dosage may not achieve the desired phosphorus removal effect, while too much dosage may lead to excessive iron concentration in the wastewater.
PH value: pH value has an impact on the phosphorus removal effect of polymerized iron sulfate. Generally, under neutral or slightly acidic conditions, the phosphorus removal effect of polymerized iron sulfate is better.
Mixing and contact time: To ensure that polymeric iron sulfate can be fully mixed and react with phosphate in water, a certain amount of mixing and contact time is usually required.
Sedimentation and filtration: The treated water usually needs to undergo sedimentation and filtration processes to remove the precipitated iron and phosphorus compounds.
Byproduct treatment: The phosphorus removal process may produce byproducts that need to be properly treated to avoid any impact on the environment.
