Comparative Costs of Wastewater Treatment Technologies

TechnologyUSD/g NH₃Cost per m³ (USD)Remarks
Biological nitrification-denitrification0.002 – 0.017 – 35Low OPEX but needs large footprint and aeration.
Air stripping (with pH adjustment)0.005 – 0.0217.5 – 70Requires heat and caustic dosing; scalable.
Steam stripping0.01 – 0.0335 – 105Energy-intensive but enables ammonia recovery.
Ion exchange0.01 – 0.0535 – 175High cost at high loadings unless ammonia is recovered.
Chemical precipitation (struvite)0.03 – 0.10105 – 350Not ideal alone for high loads; depends on phosphorus content.
Membrane separation0.05 – 0.20175 – 700Advanced option, costly unless for niche or polishing use.
Electrochemical / advanced oxidation0.10 – 0.50350 – 1,750Generally uneconomical for high loads unless integrated system.
