Phosphorus overloading is one of the major causes of eutrophication, algae bloom, and ecological degradation in natural water bodies. With tightening discharge regulations, the use of phosphorus removal agents has become essential for industries and municipalities to meet environmental standards.
Phosphorus removal agents eliminate phosphate (PO₄³⁻) from wastewater through chemical precipitation, adsorption, or coagulation synergy:
-Chemical Precipitation
Aluminum salts, iron salts, and calcium-based agents react with phosphate to form insoluble compounds such as aluminum phosphate or ferric phosphate, which are then removed by sedimentation.
-Adsorption Fixation
Some composite agents use modified minerals or adsorbents to trap and hold phosphorus, ideal for low-concentration scenarios.
-Coagulation Collaboration
Used in combination with PAC or PAM, these agents enhance settling speed and improve effluent clarity.
| Type | Composition | Application | Features |
|---|---|---|---|
| Polymerized Iron Salts | PFS, PAFC | Municipal, dyeing, papermaking | Cost-effective and fast |
| Aluminum Salts | PAC, aluminum sulfate | Medium/low phosphate | Fast precipitation |
| Lime | Calcium hydroxide | High-phosphorus wastewater, pH control | Large dosage, sludge volume |
| Composite Agents | Inorganic-organic mix | Livestock, slaughter, catering | Synergistic effect, high efficiency |
Phosphorus concentration
Different agents are suited for different concentration levels.
Water composition
COD, ammonia, and oils may affect agent selection and dosing.
Cost-efficiency
Evaluate unit cost, dosage, and sludge treatment expenses.
Compatibility
Ensure compatibility with coagulants, pH regulators, etc.
