A Nanoparticle-based Coagulation Method for Cost-effective Microalgae Harvesting

Colorado School of Mines

Contact CSM About This Technology

Technology Marketing SummaryIn this invention we report a method to harvest microalgae that is both cost-effective and efficient.
DescriptionCurrent methods (centrifugation, filtration, flotation and ultrasound sedimentation) all have draw backs in either cost or interference of downstream processes.   This method uses nanoparticles in a unique manner so the microalgae coagulate and are easily and efficiently harvested.  The nanoparticles and other materials can be massed-produced at low cost, are reusable and require no post-harvesting processes to be removed.   Benefits
  • Cost-effective
  • Efficient
  • Inert to downstream processes
Applications and Industries
  • Energy production
  • Biofuels
