SwieNitro Recovery
Turning Nitrogen Waste into Valuable Fertilizer
Ammonia recovery for circular nitrogen infrastructure
SwieNitro Recovery converts wastewater nitrogen from a costly pollutant into marketable fertilizer products.
SwieNitro Recovery develops modular spiral-wound ammonia recovery systems that enable decentralized nutrient recovery using low-grade waste heat or solar energy. Our platform helps utilities and industrial facilities reduce energy-intensive treatment, lower emissions, and create new revenue from recovered nitrogen products.
Nitrogen imbalance is one of the 14 Grand Challenges in Engineering
Ammonia production is energy and carbon-intensive
Ammonia production via Haber-Bosch process consumes ~12.5 kWh/kg-N and accounts for 1-2% of global energy use and ~1.2% of CO2 emissions.
Excess nitrogen in waste streams poses problems
Discharge through waste streams poses major environmental challenges (e.g., eutrophication, algal blooms, and public health concerns).
Utilities pay to remove nitrogen pollution, and farmers pay to buy nitrogen fertilzier, creating a multi-billion-dollar opportunity for nutrient recovery
Bay-wide loads of Nitrogen over 50,000 kg/day
U.S. Bay Area WWTPs directed to reduce nitrogen discharges by 40-60% for the 10-year plan (2024-2034), and the plant upgrades could reach as high as $11 billion.
Farmers pay money on fertilzier
Farmers pay to buy Haber-Bosch ammonia fertilizer, which accounts for 1-2% of global energy use.
SWIE: A simple, low-cost, and robust modular for ammonia recovery
The SWIE module include three layers with a spacer between the wastewater cloth and the acid cloth. Under the solar or other low-grade waste heats as energy input, the ammonia is evaporated from wastewater cloth and captured in acid cloth.
• Convert ammonia in wastewater into valuable fertilizer products
• Reduce energy demand and emissions vs. conventional removal
• Modular design for retrofit and scalable deployment
