Fraunhofer USA CEI welcomes joint development projects with industrial and government clients.

Types of project include, but are not limited to, membrane design/modification, module prototyping, systems design/ piloting, applications testing, feasibility studies, bench-marking studies etc. We work with a range of companies who are in start up/proof of concept phase to fortune 500 companies to government agencies like the Department of Energy and US Bureau of Reclamation  to help serve their separation needs. 

Completed Projects include: 

  • Fabricated system to test and evaluate the performance of medical devices
  • Evaluated water hardness sensor concept
  • Demonstrate the fouling resistance of a newly developed thin film composite (TFC) membrane for desalination made by a process called electrospray polymerization
  • Demonstrate the removal of suspended solids from an industrial process
  • Demonstrate using membranes to dewater wastewater
  • Demonstrate using membranes to remove metals from acid wastewater 

Current On-Going Projects include: 

  • 3D Printed membranes
  • Electrospray membrane fabrication
  • Novel membrane device fabrication
  • Delivery of membranes for high temperature nanofiltration
