Synergistic Activities
• University Research Collaboration: Partnered with Missouri University of Science
and Technology (Missouri S&T) under a formal R&D agreement (2015–2017) to ad-
vance ceramic-based water and wastewater treatment systems. Molecular Filtration,
Inc. contributed over $50,000 in pilot-scale equipment, intellectual property, and tech-
nical support to Dr. Muthanna Al-Dahhan’s Multiphase Reactors and Applications
Laboratory (M-REAL), supporting graduate research and technical development.
• Patent-Driven Innovation: Lead inventor on multiple U.S. and international patent
applications focused on catalytic ceramic contactors, membrane-free separation sys-
tems, and oilfield water reuse technologies. These include novel approaches to sulfur
removal, metal precipitation, and azeotropic separation for sustainable industrial water
treatment.
• Technology Commercialization: Founded Molecular Filtration, Inc. to bridge ad-
vanced chemical engineering research with real-world applications in oilfield, mining,
and industrial wastewater treatment. Initiated design and engineering of scalable ce-
ramic contactor units. Pilot and production-scale deployment is planned as part of
upcoming R&D supported by this NSF proposal.
• STEM Advocacy and Mentorship: Actively support student research and technical
training through equipment donations, real-world field data access, and consultation
with academic labs. Contributions acknowledged in graduate-level research at Mis-
souri S&T in membrane and contactor system development.
• International Collaboration and Impact: Engaged with stakeholders in the U.S. and
Middle East to identify opportunities for pilot programs and collaborative deployment
of ceramic contactor systems, contingent on NSF funding. These efforts aim to sup-
port regional water reuse, resource recovery, and environmental stewardship using
catalytic ceramic technologies.
