Polymeric iron sulfate (PFS) is commonly used in the field of water treatment, with phosphorus removal being one of its applications. The phosphorus removal process is usually achieved by forming sediment with phosphate in wastewater. To calculate the phosphorus removal amount of polymeric iron sulfate, factors such as the phosphorus concentration in the wastewater, the volume of the wastewater, and the iron content of polymeric iron sulfate need to be considered.
Determine the phosphorus concentration in wastewater: Measure the concentration of total phosphorus or organic phosphorus in wastewater, usually in milligrams per liter (mg/L).
Determine the volume of wastewater: Estimate or measure the total volume of wastewater, usually in cubic meters (m ³） In units.
Check the iron content of polymeric iron sulfate: Find the iron content of the polymeric iron sulfate product you are using. Usually expressed as a percentage.
Calculate the amount of phosphorus removal agent using the formula:
Phosphorus removal agent dosage (kg)=(phosphorus concentration in wastewater) × Volume of wastewater/(iron content of polymeric iron sulfate) × 1000)
Here, the units of wastewater phosphorus concentration and wastewater volume must match. For example, if the phosphorus concentration is mg/L, then the wastewater volume is liters (L). The final result is usually measured in kilograms (kg).
This formula is a simple calculation method that may need to be adjusted according to specific situations in practical applications. In addition, relevant processing techniques and usage instructions must be followed.
