Thrust 2 creates modular, electrified, hybrid, and distributed separation technologies to enable circular use and delivery of nitrogen-based fertilizer while optimizing phosphorus-based fertilizer circularity​. 

​

Thrust 2 objectives are:

  • Focus on upfront separation of liquid (e.g., WWTP inlet and CAFOs)​

  • Focus on pre-purification of streams to implement in T3​

  • Focus on post-separation from sludge (solids) and purification of streams from T3​

  • Focus on multisource resource recovery​

  • Focus on evaluation of fertilizer formulations delivered from T2 in the soil chemistry/ plant growth​

  • Focus on protocols to evaluate durability of materials for T2 technologies​

Testbeds

Testing CASFER Technologies in the Field

The CASFER testbeds are mobile units, or systems assembled in trailers or skid-mobile units. The testbeds integrate the technologies for the different thrusts, separations, catalysts, reactors, sensors, and control algorithms.
