Abstract

TECHNICAL ABSTRACT
With the expanding use of desalination and wastewater remediation to meet the nations fundamental
water requirements, the critical economic need for reducing energy requirements and enhancing
operational functionality can be addressed by a supported one atomic layer thick membrane that
incorporates the chemical structures to avoid fouling and scaling. The development of novel cyclic
organic synthons capable of being used as building blocks for the self-assembly of porous, Langmuir-
Film (LF) derived nanomembranes has lead to the development of large, supported membranes. The LF
derived nanomembranes provide for exquisite solute selectivity and theoretically provide the minimal
energy barrier to solvent passage. Manufacturing technology is needed to move the porous
nanomembranes from the bench top to industrial scale production.
A novel design of a small scale, one atomic thick layer batch-continuous membrane manufacturing
device that uses the inherent properties of a porous nanomembrane for deposition will be designed,
bread-boarded and tested. Standard testing conditions will be developed to demonstrate that automated
batch-continuous nanomembrane preparation is possible. This will lead to development of full scale
nanomembrane and membrane production in later phases.
PHASE I
A validated test method for demonstrating successful single Langmuir LF formation will be developed
using current. laboratory scale (~6.5cm2) LF formation technology. Different geometries of LF zone
barriers will be designed, prototyped and tested using our large (232cm2)monolayer film preparation
device (and the validated test method) to demonstrate, parallel, simultaneous LF and nanomembrane
formation by the formation of many, (6.5cm2) LF in the large device followed by crosslinking of the LF
to yield nanomembranes. This will lead to the design of a full-scale automated, parallel LF and
nanomembrane formation device in Phase II where each nanomembrane will be 232cm2.
COMMERCIAL APPLICATIONS AND OTHER BENEFITS
This one atomic layer thick membrane promises to provide high purity water in desalination, wastewater
remediation and water purification applications while providing total cost reductions on the order of
50% and reducing energy needed by 66% for desalination and 99% for purifications, During a time of
increased water scarcity and rising costs, this technology provides enhanced water security and reduced
costs to municipalities, agriculture and a wide range of industries water security.
KEY WORDS: nanomembrane water purification desalination remediation
SUMMARY FOR MEMBERS OF CONGRESS:
Novel manufacturing methods are being developed for the preparation of nanomembranes to provide
low cost, high purity water from sources as diverse as seawater, remediation and produced water from
fracking operations
