Clean Membranes

Ultrafiltration Membrane Technology

Clean Membranes is developing a new hydrophilic polymer, PAN-g-PEO (PgP) for use in ultrafiltration membranes that resist fouling and operate for long periods of time without requiring the use of cleaning chemicals. These PgP-based membranes are being deployed to address a range of pressing industrial water treatment needs, especially those associated with oily wastewater.

F-Wave

Fully Integrated PV Roofing Shingles

F-Wave is developing solar roofing tiles that harvest both photovoltaic and thermal energy to achieve overall efficiencies of up to 40%—double the efficiency of traditional glass solar panels.

F-Wave's solar tiles are designed for easy installation, without the need for specialized labor and tools, and are cost-competitive with traditional re-roofing and solar panel installations.
